The implementation starts from FastFlowLM `main`, supports only the validated Phi-4 Mini Instruct Q8_0 GGUF, and uses corelib's explicit lossy Q8_0-to-group-64 requantization APIs. + +The model is read directly from GGUF. FastFlowLM will not generate or ship an ONNX initializer manifest, an ONNX model, or converted weight files. The Phi-4 architecture and tensor-name contract live in a model-specific C++ adapter, while shape, dtype, offset, and model metadata come from the GGUF file. + +This PR produces an AIE4-enabled developer build of the normal `flm.exe`. It does not package the AIE4 runtime in MSI, WiX, or Inno Setup. + +## Fixed inputs + +### Model + +- FLM tag: `phi4-mini-it-aie4:4b` +- GGUF repository: `unsloth/Phi-4-mini-instruct-GGUF` +- GGUF revision: `78eb92a46fc37e6b524df991ed9aca9bc6aa7b80` +- GGUF file: `Phi-4-mini-instruct.Q8_0.gguf` +- Supported quantization: GGML `Q8_0` only + +### Tokenizer and configuration + +- Repository: `microsoft/Phi-4-mini-instruct` +- Revision: `cfbefacb99257ffa30c83adab238a50856ac3083` +- Files: `tokenizer.json`, `tokenizer_config.json`, and `config.json` + +The tokenizer files come from a second repository because the selected Unsloth repository does not publish the files FastFlowLM's existing tokenizer frontend consumes.

An AIE4-enabled `flm.exe` runs the model through corelib from the CLI and REST APIs. +3. The existing Phi-4 NPU2/Q4NX model continues to use its existing backend. +4. A build without AIE4 support, or an AIE4 build with no corelib DLL, still starts and runs non-AIE4 models. +5. The implementation validates the model and tokenizer contracts before creating device state. +6. No silent CPU or NPU2 fallback is possible for the AIE4 tag. +7.

An absent backend field retains the current NPU2 behavior. An unknown value is an error. + +There is no automatic hardware or format detection and no fallback. This makes a request for the AIE4 tag observable and testable: it either runs through corelib or fails. + +### Component boundaries + +#### Phi-4 frontend + +`modeling_phi4.cpp` remains responsible for: + +- backend selection; +- tokenizer setup and chat-template application; +- sampling; +- request capacity checks; +- translating the existing `AutoModel` interface to the selected causal-LM engine. + +It does not parse GGUF or call individual corelib operators. + +#### Corelib API and runtime + +A small dynamic adapter resolves only the C ABI symbols used by this backend: + +- version, dependency self-test, device-context query, errors, and cleanup; +- object lifecycle; +- stream creation and synchronization; +- tensor creation, windows, reads, and writes; +- matmul padding, Q8_0 requantized weight creation, and dispatch; +- SSMLP padding, Q8_0 requantized weight creation, and dispatch; +- RMSNorm weight creation, padding, and dispatch; +- flat-MHA padding and dispatch. + +The adapter owns no model policy. It converts failed statuses into exceptions that retain the corelib status, call name, and thread-local detail message. RAII wrappers release every returned object. + +Corelib is not loaded during process startup. It is loaded when an AIE4 model is selected. Runtime lookup order is: + +1. the absolute DLL named by `FLM_AIE4_CORELIB_PATH`; +2. `/aie4/ryzenai_corelib.dll`. + +The loader does not search the current working directory. After loading, it resolves the version functions first, requires ABI `0.3.0`, resolves the remaining symbols, runs the dependency self-test, and verifies an AIE4 device context exists. + +#### GGUF package + +`Phi4GgufPackage` owns a read-only mapping of the single GGUF file and exposes validated, non-owning tensor views whose lifetime cannot exceed the mapping. It parses only the GGUF v3 facilities used by the pinned model: + +- little-endian header; +- metadata scalar, string, and array encodings; +- tensor names, dimensions, GGML types, and relative offsets; +- model alignment and tensor-data start. + +The parser performs checked arithmetic for every count, offset, alignment, and byte-length calculation. A truncated directory, duplicate tensor name, unsupported value type that cannot be skipped safely, out-of-range tensor, overlapping invalid range, or malformed string is a load error. + +The model-facing API is intentionally narrow: + +```cpp +TensorView RequireQ8(name, expected_shape); +FloatTensorView RequireF32(name, expected_shape); +ProjectionViews AttentionQkv(layer); +ProjectionViews GateUp(layer); +GgufPhi4Metadata Metadata(); +``` + +The adapter hardcodes Phi-4 Mini's expected tensor names and architecture. QKV and gate/up tensors are fused in this GGUF; the adapter splits each into row-aligned byte-range views without dequantizing or copying it. Q8_0 rows consist of complete 34-byte blocks for 32 weights, so every allowed split must fall on a complete-row boundary. + +#### Phi-4 AIE4 engine + +The execution engine selectively carries forward the hardware-validated structure from PR #706: + +- one corelib stream; +- padded tensors sized from corelib's helper APIs; +- fixed-size K/V caches; +- prefill and one-token decode; +- explicit synchronization at producer/consumer boundaries; +- host-side lazy embedding lookup; +- Phi-4 partial rotary tables; +- corelib matmul, fused SSMLP, standalone RMSNorm, and flat MHA dispatch; +- a maximum sequence length of 4096 and maximum usable decode window of 4095. + +The source path changes completely: no ONNX initializers and no manifest are accepted. + +For each quantized projection, the engine passes a raw Q8_0 block view to `ryzenai_corelib_*_weights_create_gguf_requantized` with group size 64. Weight objects are created serially. The corelib API documents an open, unattributed all-zero-output incident correlated with concurrent requantized creates; avoiding concurrency is the measured safe configuration and is required for this first implementation. + +GGUF stores norms as F32. The adapter converts only the required norm vectors and epsilon to BF16 at model load. Embedding rows are decoded lazily for requested token IDs instead of materializing the full 200064-by-3072 embedding. RoPE tables are derived once from the GGUF's Phi-3/Phi-4 rope metadata and uploaded as FP32. + +## Model contract validation + +Validation occurs before device weight creation wherever possible. The package must match all of these constraints: + +- the expected Phi-3/Phi-4 GGUF architecture identifier; +- 32 decoder layers; +- hidden size 3072; +- intermediate size 8192; +- 24 attention heads; +- 8 key/value heads; +- head size 128; +- vocabulary size 200064; +- partial rotary dimension 96; +- RMS epsilon `1e-5`; +- maximum sequence length 4096; +- `phi3.rope.dimension_count` equal to 96; +- finite, positive `phi3.rope.freq_base` and `phi3.rope.scaling.attn_factor`; +- `phi3.rope.scaling.original_context_length` equal to 4096; +- `rope_factors_short.weight`, when present, is F32 with exactly 48 elements; +- the long-rope branch is rejected because this backend supports only the original 4096-token window; +- every required projection present with the exact expected logical shape; +- every projection, tied embedding, and LM head source is Q8_0; +- every required norm present in the supported floating type; +- `output.weight` is absent and `token_embd.weight` is used for both embedding and LM head, as in the pinned model; +- tokenizer vocabulary size agrees with GGUF; +- EOS IDs include 200020 and 199999; +- BOS behavior agrees; +- the chat template contains the required Phi-4 user, end, and assistant markers. + +The error names the model field or tensor, its actual value, and the expected value. The loader does not repair, reinterpret, or silently accept a mismatch. + +## Pull and catalog design + +The existing catalog format assumes one base repository per model. Retain the existing string-only `files` array and add an optional `file_sources` object keyed by those file names. Each override contains `url` and `revision`; files without an override continue to use the model's base URL unchanged. `model_info.json` remains the source of expected remote size and content hash for `pull` and `check`. No existing catalog entry needs migration. + +For each file, pull: + +1. constructs a URL from that file's fixed repository and revision; +2. downloads or resumes into a temporary path; +3. validates expected size and SHA-256; +4. atomically renames the completed file into the model directory. + +A model is available only when all required files validate. `flm check` uses the same per-file records. No generated overlay is copied into the model directory. + +The final directory is: + +```text +models/phi4-mini-it-aie4/ +├── Phi-4-mini-instruct.Q8_0.gguf +├── tokenizer.json +├── tokenizer_config.json +└── config.json +``` + +## Build and runtime configuration + +The feature is disabled by default. An AIE4 developer build enables: + +```text +FLM_ENABLE_CORELIB_AIE4=ON +RYZENAI_CORELIB_INCLUDE_DIR= +``` + +The build consumes the public header from the pinned corelib commit but does not link its import library. Calls go through the dynamically resolved function table. The normal `flm.exe` is produced and supports `pull`, `run`, and `serve`. + +This PR does not copy runtime DLLs. The developer supplies `ryzenai_corelib.dll` and its DynamicDispatch, XRT, and RyzenMM dependency closure. `FLM_AIE4_CORELIB_PATH` or the executable-relative `aie4` directory identifies corelib itself; its dependent DLL directory must be available to the Windows loader. + +A default build has no corelib compile or runtime requirement. An AIE4-enabled build with a missing runtime still starts and can run ordinary models; selecting `phi4-mini-it-aie4:4b` reports the missing runtime. + +## Request lifecycle and error policy + +A process-wide AIE4 access manager serializes AIE4 generation. One model instance handles one active generation at a time, matching the stream and mutable KV-cache ownership model. + +Failures before any operation is submitted are recoverable model/request errors. Failures after submission, or during synchronization, leave device completion uncertain. The model instance is then marked poisoned, its conversational state is cleared, and subsequent requests are refused until the model is unloaded and recreated. FastFlowLM does not continue on potentially inconsistent KV state. + +A cancellation is checked before prefill and between decode steps. It never destroys a stream while work is outstanding; submitted work is synchronized before the request releases model state. + +Capacity checks happen before submission. They account for the rendered prompt and requested generation budget and enforce the AIE4 decode limit of 4095. Unbounded/sentinel generation requests are capped rather than allowed to reach an unsupported attention window. + +## Expected file changes + +### Existing files + +```text +src/CMakeLists.txt +src/CMakePresets.json +src/common/AutoModel/automodel.cpp +src/common/AutoModel/modeling_phi4.cpp +src/include/AutoModel/automodel.hpp +src/include/AutoModel/modeling_phi4.hpp +src/pull/model_downloader.cpp +src/pull/model_downloader.hpp +src/model_list.json +src/model_info.json +src/runner/runner.cpp +src/server/rest_handler.cpp +src/server/server.cpp +src/src/main.cpp +``` + +Only files proven necessary during implementation should be changed.

This PR locates only `ryzenai_corelib.dll`; dependent DLL discovery remains the Windows loader's responsibility. -- The sibling `../ryzenai-corelib` working tree is currently on another branch, while `origin/main` points to the required commit. Verification and build commands must address commit `3c35aebdefa3f0c2255668bab1be5648ece320f8` explicitly and must not overwrite sibling work. -- Exact remote file sizes and SHA-256 values are immutable implementation data obtainable from the pinned URLs. Task 5 computes and independently verifies them before catalog edits; no unverified value may be committed. -- Real-AIE4 performance values are not known until Task 7 runs. The documentation commit is blocked until the acceptance script has emitted actual values and provenance. - ---- - -## Repository Findings and Reuse Boundaries - -- Current `src/common/AutoModel/modeling_phi4.cpp` always calls `_shared_load_model`, constructs `Q4NX`, and creates `phi4_npu`; backend selection must be added there, not in `get_auto_model`. -- Current `_shared_load_model` in `src/common/AutoModel/automodel.cpp` combines generic model/tokenizer state with NPU2 `npu_xclbin_manager` creation. Split those responsibilities so the AIE4 route never constructs the legacy backend. -- Current downloads write directly to the final path and use base-repository URLs. The per-file source and atomic-resume behavior therefore require coordinated changes in `model_downloader.*` and `download_model.*`. -- Current server request queuing already serializes most NPU endpoints, but `/v1/completions` is omitted and exception paths manually release the lock. Extend the existing mechanism rather than adding a second queue. -- `origin/pr/706` supplies useful shapes for the dynamic loader, move-only handles, shape plan, fake corelib, frontend routing, and engine sequencing. Its source contract is ONNX/manifest-based, its symbol list predates ABI 0.3.0, its environment variable is different, and its post-submit policy terminates the process; none of those parts are reusable unchanged. -- The pinned corelib header supplies tensor windows, matmul/SSMLP Q8_0 requantized creation, RMSNorm scale creation/dispatch, and flat-MHA. The implementation must resolve exactly those public functions and no testing-only symbols. - -## Locked Interfaces - -Use these names and signatures throughout the tasks so independently implemented pieces join without renaming: - -```cpp -namespace flm::corelib { - -struct CorelibVersion { - std::uint32_t major; - std::uint32_t minor; - std::uint32_t patch; -}; - -class CorelibError final : public std::runtime_error { -public: - CorelibError(ryzenai_corelib_status status, - std::string call, - std::string detail, - std::string status_text); - ryzenai_corelib_status status() const noexcept; - const std::string& call() const noexcept; - const std::string& detail() const noexcept; -}; - -struct CorelibFunctions { - decltype(&::ryzenai_corelib_get_version) get_version; - decltype(&::ryzenai_corelib_status_to_string) status_to_string; - decltype(&::ryzenai_corelib_get_last_error_message) get_last_error_message; - decltype(&::ryzenai_corelib_selftest_dependencies) selftest_dependencies; - decltype(&::ryzenai_corelib_has_device_context) has_device_context; - decltype(&::ryzenai_corelib_object_release) object_release; - decltype(&::ryzenai_corelib_create_stream) create_stream; - decltype(&::ryzenai_corelib_stream_synchronize) stream_synchronize; - decltype(&::ryzenai_corelib_create_device_tensor) create_device_tensor; - decltype(&::ryzenai_corelib_create_tensor_window) create_tensor_window; - decltype(&::ryzenai_corelib_tensor_write) tensor_write; - decltype(&::ryzenai_corelib_tensor_read) tensor_read; - decltype(&::ryzenai_corelib_tensor_get_byte_size) tensor_get_byte_size; - decltype(&::ryzenai_corelib_tensor_get_data_type) tensor_get_data_type; - decltype(&::ryzenai_corelib_matmul_bf16_pad_shape) matmul_pad_shape; - decltype(&::ryzenai_corelib_matmul_bf16_weights_create_gguf_requantized) - matmul_weights_create_gguf_requantized; - decltype(&::ryzenai_corelib_matmul_bf16) matmul; - decltype(&::ryzenai_corelib_ssmlp_bf16_pad_rows) ssmlp_pad_rows; - decltype(&::ryzenai_corelib_ssmlp_bf16_weights_create_gguf_requantized) - ssmlp_weights_create_gguf_requantized; - decltype(&::ryzenai_corelib_ssmlp_bf16) ssmlp; - decltype(&::ryzenai_corelib_rmsnorm_bf16_weights_create_scale) - rmsnorm_weights_create_scale; - decltype(&::ryzenai_corelib_rmsnorm_bf16_pad_rows) rmsnorm_pad_rows; - decltype(&::ryzenai_corelib_rmsnorm_bf16) rmsnorm; - decltype(&::ryzenai_corelib_flat_mha_bf16_pad_rows) flat_mha_pad_rows; - decltype(&::ryzenai_corelib_flat_mha_bf16) flat_mha; - decltype(&::ryzenai_corelib_cleanup) cleanup; -}; - -class CorelibApi final { -public: - using Resolver = std::function; - static std::shared_ptr Load(const std::filesystem::path& dll); - static std::shared_ptr ResolveForTest(Resolver resolver); - static std::filesystem::path ResolveLibraryPath( - const std::filesystem::path& executable_dir); - const CorelibFunctions& functions() const noexcept; - CorelibVersion runtime_version() const noexcept; - void Check(ryzenai_corelib_status status, std::string_view call) const; - void RegisterObject() const noexcept; - void Release(void* object) const noexcept; - std::size_t live_object_count() const noexcept; -}; - -class CorelibRuntime final { -public: - static std::shared_ptr GetOrCreate( - const std::filesystem::path& executable_dir); - static std::shared_ptr CreateForTest( - std::shared_ptr api); - static void ShutdownProcess(); - std::unique_lock AcquireExecution(); - const std::shared_ptr& api() const noexcept; -}; - -} // namespace flm::corelib -``` - -`UniqueObject` is move-only and calls `CorelibApi::Release` exactly once.

Every allocation uses the maximum helper-returned extent, never a hand-rounded M. - -```powershell -cmake --build src/build/phi4-corelib-tests --config Release --target test_phi4_shape_plan -ctest --test-dir src/build/phi4-corelib-tests -C Release -R "^test_phi4_shape_plan$" --output-on-failure -``` - -Expected: all shape-plan tests pass and every fake helper observation uses group 64. - -- [ ] **Step 5: Extend the fake corelib and write failing engine-load tests** - -The fake must implement tensors with shape/dtype/storage, tensor windows retaining parent storage, Q8_0 weight creation records, RMSNorm weight records, stream dispatch records, injected pre-submit/post-submit/synchronize failures, and an in-flight flag. Define: - -```cpp -TestEngineCreatesOneStreamAndPersistentHelperSizedTensors(); -TestEngineCreates129Matmul32SsmlpAndOneRmsNormWeight(); -TestEveryProjectionUsesQ8RequantizedGroup64Threads0(); -TestWeightCreationIsSerialAndNeverExceedsOneInFlightCreate(); -TestQkvAndGateUpPointersMatchExactMappedSubranges(); -TestNormsAndEpsilonReachCorelibAsBf16(); -TestEmbeddingMappingOutlivesAllLazyRowReads(); -TestNoDeviceObjectExistsWhenPackageValidationFails(); -``` - -Require all 162 weight creates to happen in deterministic layer order; this makes accidental parallelization visible and protects the documented all-zero-output mitigation. - -- [ ] **Step 6: Implement engine construction and serial weight creation** - -Create initial RMSNorm weights from `blk.0.attn_norm.weight`. For each layer create Q/K/V/O matmul weights and one SSMLP weight whose `norm0` is `blk.i.ffn_norm.weight` and whose `norm1` is `blk.(i+1).attn_norm.weight`, except layer 31 uses `output_norm.weight`. Create the LM-head matmul from `token_embd.weight`. Every GGUF component type is Q8_0 and every descriptor group is 64. - -Allocate once: hidden/residual/skip, Q, K, attention output, one-row LM input, logits, FP32 cosine/sine tables, and 32 K plus 32 V caches `[8,4096,128]`. Upload RoPE once. Do not materialize the embedding table. - -- [ ] **Step 7: Write failing prefill/decode/sequencing tests** - -Define and invoke: - -```cpp -TestPrefillDecodesEmbeddingRowsAndAdvancesPosition(); -TestDecodeUsesOneRowAndAdvancesPosition(); -TestVProjectionWritesWindowAtPositionTimes128(); -TestEachLayerOrdersQKVThenMhaThenOThenSsmlpOnOneStream(); -TestBuffersAreZeroPaddedBeforeSubmissionForEachRowBucket(); -TestForwardSynchronizesBeforeHostReadAndLmHeadRead(); -TestKVCachesRemainFixedAt8By4096By128(); -TestPrompt4096IsAcceptedOnlyWithoutARequestedDecodeToken(); -TestTotalDecodeWindowStopsAt4095(); -TestClearContextResetsLogicalPositionWithoutRecreatingWeights(); -TestCheckpointRestoreChangesOnlyLogicalPosition(); -TestPreSubmitFailureIsRecoverable(); -TestPostSubmitFailureSynchronizesThenPoisonsAndClearsState(); -TestSynchronizeFailurePoisonsAndClearsState(); -TestPoisonedInstanceRejectsEveryLaterEntryPoint(); -TestCancellationBoundaryLeavesNoOutstandingFakeWork(); -``` - -The fake call log must prove there is no CPU/NPU2 call and no lossless `*_create_gguf` call. The V-window assertion uses shape `[8,4096-position,128]` and element offset `position * 128`. - -- [ ] **Step 8: Implement the minimal execution state machine** - -At the beginning of each model step, reject a poisoned engine and validate IDs/capacity. Decode only requested embedding rows to FP32, write and zero helper-required input/residual extents, dispatch RMSNorm in place, then for each layer dispatch Q, K, V-to-window, flat-MHA, O, and SSMLP on the same stream. Swap residual/skip handles only after queueing SSMLP. Synchronize before reading the final hidden row, write it to the one-row LM input, dispatch LM head, synchronize, and read logits as BF16 into the existing `buffer` expected by `Sampler`. - -Track whether any submit succeeded. On a pre-submit failure, leave `poisoned_ == false`. On any later exception, best-effort synchronize, set `poisoned_ = true`, clear logical position/checkpoint, and throw an error that includes the failed corelib call. `clear_context()` must not clear `poisoned_`; only destroying/recreating the model does. - -- [ ] **Step 9: Run GREEN and leak/order checks** - -```powershell -cmake --build src/build/phi4-corelib-tests --config Release --target ` - test_phi4_host test_phi4_shape_plan test_phi4_engine -ctest --test-dir src/build/phi4-corelib-tests -C Release ` - -R "^test_phi4_(host|shape_plan|engine)$" --output-on-failure -``` - -Expected: all tests pass; fake live-object count returns to zero after engine destruction; maximum simultaneous requantized creates is one; no submitted work remains when a request/cancellation test returns. - -- [ ] **Step 10: Refactor repeated create/dispatch/error wrappers and rerun Step 9** - -Keep model policy in `phi4_corelib_aie4.cpp`; keep GGUF parsing out of the engine and corelib calls out of the GGUF package/host helpers. - -- [ ] **Step 11: Commit review gate** - -```powershell -git add src/include/models/phi4/phi4_corelib_shape_plan.hpp ` - src/include/models/phi4/phi4_corelib_host.hpp ` - src/include/models/phi4/phi4_corelib_aie4.hpp ` - src/common/corelib/phi4_corelib_shape_plan.cpp ` - src/common/corelib/phi4_corelib_host.cpp ` - src/common/corelib/phi4_corelib_aie4.cpp ` - src/common/corelib/corelib_sources.cmake ` - src/test/phi4_corelib_aie4 -git commit -m "feat: add corelib-backed Phi-4 AIE4 engine" -``` - -Expected: engine/fake tests pass; no CLI/catalog route selects it yet. - -### Task 4: Explicit Phi-4 Frontend Routing and Request Lifecycle - -**Files:** -- Modify: `src/include/AutoModel/automodel.hpp` -- Modify: `src/common/AutoModel/automodel.cpp` -- Modify: `src/include/AutoModel/modeling_phi4.hpp` -- Modify: `src/common/AutoModel/modeling_phi4.cpp` -- Modify: `src/runner/runner.cpp` -- Modify: `src/server/rest_handler.cpp` -- Modify: `src/server/server.hpp` -- Modify: `src/server/server.cpp` -- Create: `src/test/phi4_corelib_aie4/test_phi4_frontend.cpp` -- Modify: `src/test/phi4_corelib_aie4/CMakeLists.txt` - -**Interfaces:** -- Consumes the package/runtime/engine from Tasks 1–3. -- Produces `ModelRequestError`, `lm_uniform_input_t::requested_max_new_tokens`, and `AutoModel::uses_corelib_aie4()` from **Locked Interfaces**. -- `Phi4::load_model` recognizes exactly `corelib_aie4_gguf`; no backend field remains NPU2. - -- [ ] **Step 1: Write failing routing and initialization tests** - -Inject an engine factory under `FLM_CORELIB_TESTING` and define: - -```cpp -TestAbsentBackendStillBuildsQ4nxPhi4Npu(); -TestCorelibAie4GgufBuildsOnlyTheCorelibEngine(); -TestUnknownAndNonStringBackendAreErrors(); -TestFeatureOffRejectsAie4TagWithoutIncludingCorelibHeaders(); -TestInvalidPackageFailsBeforeRuntimeAndDeviceCreation(); -TestMissingCorelibFailsOnlyWhenAie4ModelLoads(); -TestOrdinaryModelLoadsAfterAnAie4RuntimeLoadFailure(); -TestPreemptionIsRejectedForTheAie4Route(); -``` - -Split `_shared_load_model` so the test can assert the AIE4 branch initializes config/tokenizer/sampler state without constructing `npu_xclbin_manager`; leave `_shared_load_model` behavior unchanged for every legacy caller. - -- [ ] **Step 2: Implement explicit routing and tokenizer contract checks** - -`Phi4::load_model` must: - -1. resolve the backend string; -2. for AIE4, reject preemption and context outside `1..4096`; -3. parse `config.json`, `tokenizer.json`, and `tokenizer_config.json` and open the single GGUF; -4. call `ValidatePhi4Contract` before `CorelibRuntime::GetOrCreate` or any engine/device creation; -5. initialize the existing `Tokenizer`, chat template, sampler, and EOS list `{200020, 199999}` after proving `tokenizer.json` maps `<|end|>`/`<|endoftext|>` to those IDs, GGUF declares EOS 200020, `config.json` declares EOS 199999, and `tokenizer_config.json` disables automatic BOS; -6. lazily acquire runtime and construct `phi4_corelib_aie4`; -7. set `uses_corelib_aie4_` only after all construction succeeds. - -Use `Phi-4-mini-instruct.Q8_0.gguf` as the only accepted model filename.

A poisoned refusal is 500 with `session_cleared == true` and names that unload/reload is required. - -- [ ] **Step 4: Implement AIE4-specific insert/generate behavior** - -Pass `requested_max_new_tokens` into `lm_uniform_input_t` from CLI `generate_limit`, `/api/generate:max_tokens`, `/api/chat:options.num_predict`, `/v1/chat/completions:max_tokens|max_completion_tokens`, and `/v1/completions:max_tokens`. Normalize absent or non-positive sentinel limits to an unbounded request, then cap generation to `4095 - rendered_prompt_tokens`; do not pass the legacy default 4096 through as an explicit AIE4 budget. - -Check cancellation immediately before prefill and before every `forward` call. Since each engine call synchronizes before returning, a cancellation observed between calls has no outstanding work. Preserve existing tokenization, chat-template rendering, sampling settings, and output streams. - -- [ ] **Step 5: Make server serialization exception-safe and complete** - -Keep the existing process-wide NPU queue. Add `/v1/completions` to `requires_npu_access`, replace duplicated release calls with a move-only completion guard owned by each dequeued request, and prove exactly one release on success, JSON parse failure, model error, cancellation, and unknown exception. Do not create a second AIE4-only queue. - -Map `ModelRequestError::http_code()` to HTTP 400 or 500 for non-streaming responses. For OpenAI streaming after headers/data started, emit one structured error event followed by `[DONE]`; before streaming starts, return the normal JSON error response. Include `session_cleared` in the error body. - -- [ ] **Step 6: Run frontend and compile-gate tests** - -```powershell -cmake --build src/build/phi4-corelib-tests --config Release --target ` - test_phi4_frontend phi4_frontend_compile_off phi4_frontend_compile_on -ctest --test-dir src/build/phi4-corelib-tests -C Release ` - -R "^test_phi4_frontend$" --output-on-failure -cmake --build --preset windows-default -cmake --build --preset windows-aie4 -``` - -Expected: routing/lifecycle tests pass; feature-off production TUs compile without `RYZENAI_CORELIB_INCLUDE_DIR`; both full builds succeed; legacy `phi4-mini-it:4b` still routes to Q4NX/NPU2. - -- [ ] **Step 7: Refactor shared request-finalization logic and rerun Step 6** - -Centralize only typed-error JSON construction and exactly-once queue release; retain each endpoint's existing response schema and stream formatter.

An absent backend field retains the current NPU2 behavior. An unknown value is an error. - -There is no automatic hardware or format detection and no fallback.

It converts failed statuses into exceptions that retain the corelib status, call name, and thread-local detail message. RAII wrappers release every returned object. - -Corelib is not loaded during process startup. It is loaded when an AIE4 model is selected. Runtime lookup order is: - -1. the absolute DLL named by `FLM_AIE4_CORELIB_PATH`; -2. `/aie4/ryzenai_corelib.dll`. - -The loader does not search the current working directory. After loading, it resolves the version functions first, requires ABI `0.3.0`, resolves the remaining symbols, runs the dependency self-test, and verifies an AIE4 device context exists. - -#### GGUF package - -`Phi4GgufPackage` owns a read-only mapping of the single GGUF file and exposes validated, non-owning tensor views whose lifetime cannot exceed the mapping. It parses only the GGUF v3 facilities used by the pinned model: - -- little-endian header; -- metadata scalar, string, and array encodings; -- tensor names, dimensions, GGML types, and relative offsets; -- model alignment and tensor-data start. - -The parser performs checked arithmetic for every count, offset, alignment, and byte-length calculation. A truncated directory, duplicate tensor name, unsupported value type that cannot be skipped safely, out-of-range tensor, overlapping invalid range, or malformed string is a load error. - -The model-facing API is intentionally narrow: - -```cpp -TensorView RequireQ8(name, expected_shape); -FloatTensorView RequireF32(name, expected_shape); -ProjectionViews AttentionQkv(layer); -ProjectionViews GateUp(layer); -GgufPhi4Metadata Metadata(); -``` - -The adapter hardcodes Phi-4 Mini's expected tensor names and architecture. QKV and gate/up tensors are fused in this GGUF; the adapter splits each into row-aligned byte-range views without dequantizing or copying it. Q8_0 rows consist of complete 34-byte blocks for 32 weights, so every allowed split must fall on a complete-row boundary. - -#### Phi-4 AIE4 engine - -The execution engine selectively carries forward the hardware-validated structure from PR #706: - -- one corelib stream; -- padded tensors sized from corelib's helper APIs; -- fixed-size K/V caches; -- prefill and one-token decode; -- explicit synchronization at producer/consumer boundaries; -- host-side lazy embedding lookup; -- Phi-4 partial rotary tables; -- corelib matmul, fused SSMLP, standalone RMSNorm, and flat MHA dispatch; -- a maximum sequence length of 4096 and maximum usable decode window of 4095. - -The source path changes completely: no ONNX initializers and no manifest are accepted. - -For each quantized projection, the engine passes a raw Q8_0 block view to `ryzenai_corelib_*_weights_create_gguf_requantized` with group size 64. Weight objects are created serially. The corelib API documents an open, unattributed all-zero-output incident correlated with concurrent requantized creates; avoiding concurrency is the measured safe configuration and is required for this first implementation. - -GGUF stores norms as F32. The adapter converts only the required norm vectors and epsilon to BF16 at model load. Embedding rows are decoded lazily for requested token IDs instead of materializing the full 200064-by-3072 embedding. RoPE tables are derived once from the GGUF's Phi-3/Phi-4 rope metadata and uploaded as FP32. - -## Model contract validation - -Validation occurs before device weight creation wherever possible. The package must match all of these constraints: - -- the expected Phi-3/Phi-4 GGUF architecture identifier; -- 32 decoder layers; -- hidden size 3072; -- intermediate size 8192; -- 24 attention heads; -- 8 key/value heads; -- head size 128; -- vocabulary size 200064; -- partial rotary dimension 96; -- RMS epsilon `1e-5`; -- maximum sequence length 4096; -- `phi3.rope.dimension_count` equal to 96; -- finite, positive `phi3.rope.freq_base` and `phi3.rope.scaling.attn_factor`; -- `phi3.rope.scaling.original_context_length` equal to 4096; -- `rope_factors_short.weight`, when present, is F32 with exactly 48 elements; -- the long-rope branch is rejected because this backend supports only the original 4096-token window; -- every required projection present with the exact expected logical shape; -- every projection, tied embedding, and LM head source is Q8_0; -- every required norm present in the supported floating type; -- `output.weight` is absent and `token_embd.weight` is used for both embedding and LM head, as in the pinned model; -- tokenizer vocabulary size agrees with GGUF; -- `tokenizer.json` maps `<|end|>` to 200020 and `<|endoftext|>` to 199999; -- GGUF identifies 200020 as its EOS token and `config.json` identifies 199999, so the frontend stop set is their explicit union `{200020, 199999}`; -- `tokenizer_config.json` has `add_bos_token == false` and the frontend does not prepend `config.json`'s BOS token; -- the chat template contains the required Phi-4 user, end, and assistant markers. - -The error names the model field or tensor, its actual value, and the expected value. The loader does not repair, reinterpret, or silently accept a mismatch. - -## Pull and catalog design - -The existing catalog format assumes one base repository per model. Retain the existing string-only `files` array and add an optional `file_sources` object keyed by those file names. Each override contains `url` and `revision`; files without an override continue to use the model's base URL unchanged. `model_info.json` remains the source of expected remote size and content hash for `pull` and `check`. No existing catalog entry needs migration. - -For each file, pull: - -1. constructs a URL from that file's fixed repository and revision; -2. downloads or resumes into a temporary path; -3. validates expected size and SHA-256; -4. atomically renames the completed file into the model directory. - -A model is available only when all required files validate. `flm check` uses the same per-file records. No generated overlay is copied into the model directory. - -The final directory is: - -```text -models/phi4-mini-it-aie4/ -├── Phi-4-mini-instruct.Q8_0.gguf -├── tokenizer.json -├── tokenizer_config.json -└── config.json -``` - -## Build and runtime configuration - -The feature is disabled by default. An AIE4 developer build enables: - -```text -FLM_ENABLE_CORELIB_AIE4=ON -RYZENAI_CORELIB_INCLUDE_DIR= -``` - -The build consumes the public header from the pinned corelib commit but does not link its import library. Calls go through the dynamically resolved function table. The normal `flm.exe` is produced and supports `pull`, `run`, and `serve`. - -This PR does not copy runtime DLLs. The developer supplies `ryzenai_corelib.dll` and its DynamicDispatch, XRT, and RyzenMM dependency closure. `FLM_AIE4_CORELIB_PATH` or the executable-relative `aie4` directory identifies corelib itself; its dependent DLL directory must be available to the Windows loader. - -A default build has no corelib compile or runtime requirement. An AIE4-enabled build with a missing runtime still starts and can run ordinary models; selecting `phi4-mini-it-aie4:4b` reports the missing runtime. - -## Request lifecycle and error policy - -A process-wide AIE4 access manager serializes AIE4 generation. One model instance handles one active generation at a time, matching the stream and mutable KV-cache ownership model. - -Failures before any operation is submitted are recoverable model/request errors. Failures after submission, or during synchronization, leave device completion uncertain. The model instance is then marked poisoned, its conversational state is cleared, and subsequent requests are refused until the model is unloaded and recreated. FastFlowLM does not continue on potentially inconsistent KV state. - -A cancellation is checked before prefill and between decode steps. It never destroys a stream while work is outstanding; submitted work is synchronized before the request releases model state. - -Capacity checks happen before submission. They account for the rendered prompt and requested generation budget and enforce the AIE4 decode limit of 4095. Unbounded/sentinel generation requests are capped rather than allowed to reach an unsupported attention window. - -## Expected file changes - -### Existing files - -```text -src/CMakeLists.txt -src/CMakePresets.json -src/common/AutoModel/automodel.cpp -src/common/AutoModel/modeling_phi4.cpp -src/include/AutoModel/automodel.hpp -src/include/AutoModel/modeling_phi4.hpp -src/pull/model_downloader.cpp -src/pull/model_downloader.hpp -src/model_list.json -src/model_info.json -src/runner/runner.cpp -src/server/rest_handler.cpp -src/server/server.cpp -src/src/main.cpp -``` - -Only files proven necessary during implementation should be changed.

Performance is descriptive; no threshold is claimed. Two numbers are deliberately not presented as throughput. The record's load_duration is 1.5 us, which is the Ollama-compatible field on an already warm server rather than a model load, so load was measured separately over three fresh processes. The ten fresh-process CLI cycles report 3.70-20.26 tok/s because each pays the one-time kernel and ELF setup inside its own eight-token window. The model card separates the two context limits that were previously conflated. The 4096 ceiling is a correctness boundary: it is Phi-4-mini's rope.scaling.original_context_length, LongRoPE selects factors by sequence length, and only the short branch is derived here. The further step down to 4095 is this frontend's own conservatism so an admitted request can always finish, and is not imposed by corelib. Also records the one unexplained reply that degenerated into a markdown image URL, and corrects the emitter comment: the unbounded ConvertTo-Json allocation reproduces on PowerShell 7.0.0 as well, so a newer engine is not a fix.

This backend gives you 4095. That is a real functional regression and it has two separate causes, which are worth keeping apart. + +**The 4096 ceiling is a correctness boundary, not a buffer size.** 4096 is exactly Phi-4-mini's `rope.scaling.original_context_length`. LongRoPE selects its factors by *sequence length*, not per position: at or below the original length the short factors apply, above it the long ones do. This implementation derives only the short branch, so 4096 is the point past which the rope tables would silently be wrong. It is enforced rather than assumed — loading fails with `invalid Phi-4 RoPE metadata` unless the GGUF reports `rope.scaling.original_context_length` of exactly 4096. Raising this ceiling means deriving the long factors, not enlarging an array. + +**The extra −1 is this frontend's own conservatism.** `kMaxDecodeWindow` is 4095, one below the attention window, so that any request the server admits is guaranteed to have room to finish rather than failing partway. It costs exactly one token and it is not imposed by corelib. + +### No fallback + +Backend selection is explicit: it comes from `execution_backend` in the model catalog and is never inferred from hardware, filename, or quantization level. If corelib is missing, unloadable, or the wrong version, this tag **fails to load with a diagnostic** — it will not quietly fall back to CPU or to the NPU2/Q4NX backend. A build without AIE4 support, and an AIE4 build with no DLL present, both still start and run every other model, including `phi4-mini-it:4b`. + --- \ No newline at end of file diff --git a/src/test/phi4_corelib_aie4/run_real_aie4_acceptance.ps1 b/src/test/phi4_corelib_aie4/run_real_aie4_acceptance.ps1 index 848a75db6..5cc4c4da8 100644 --- a/src/test/phi4_corelib_aie4/run_real_aie4_acceptance.ps1 +++ b/src/test/phi4_corelib_aie4/run_real_aie4_acceptance.ps1 @@ -4,7 +4,10 @@ param( [string]$CorelibDll = 'C:/Users/chiz/work/ryzenai-corelib/install/bin/ryzenai_corelib.dll', [string]$Output = 'src/build-aie4/phi4-gguf-aie4-acceptance.json', [int]$Port = 52625, - [string]$Python = 'python' + [string]$Python = 'python', + # Diagnostics only: skips the 16-minute CLI matrix so the REST phase can be + # iterated on quickly.

The startup SHA-256 check over the 4 GB GGUF is ~28 s, 62% of the wait, and happens before the engine is constructed. Weight requantization is 15 s. Everything else is under a quarter of a second. The integrity check is also ~8x slower than the work needs: Get-FileHash over the same file on the same machine takes 3.67 s against ~28 s for calculate_file_sha256, which uses a portable pure-C++ SHA-256 with no hardware acceleration.

From 372a03907dabc8cb277c5bd99701c1e59e0bf062 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E2=80=9CChi?= Date: Sat, 12 Sep 2026 02:18:01 -0700 Subject: [PATCH 36/48] perf: stop re-hashing the model at startup, and give the packer a thread hint Two independent costs in the ~45 s startup, measured not assumed. The larger one is the startup integrity check: is_model_downloaded re-hashed every pinned file on every launch, ~28 s of SHA-256 over the 4 GB GGUF, 62% of the wait. That is a pull-time concern; the parameter to skip it already existed and simply was not passed. The run and serve paths now ask for status only. `flm pull` and `flm check` are unchanged and still verify in full, so a corrupt file is still caught -- at the next explicit check rather than at every launch. The smaller one is the packer. corelib treats a threads hint of 0 as ONE, deliberately, and this requantizing path is compute-bound and scales with it. The hint is per-create and the creates stay serialized. corelib's header records that loading a model with 8 CONCURRENT creates on this entry point failed 2 of 10 with all-zero output -- token id 0 at every step -- against 0 of 10 serialized and 0 of 10 for the ONNX path, with attribution open and the leading hypothesis an incomplete host-to-device sync. That is the faster configuration and it is deliberately not taken.

Mirror the layout common/models/phi4 already uses: include/models/phi4/flm/ phi4_npu.hpp, phi4_npu_sequence.hpp include/models/phi4/corelib/ phi4_corelib_*.hpp A grep for models//corelib/ now finds everything the corelib path pulls in. Moves only — no content change beyond the include paths in builtin_backends.cpp, automodel.hpp, the corelib sources and the tests, plus the layout section and links in common/models/README.md. Nothing globs or lists include/models, so no CMake change was needed.

The frontend (new families only) + +If the family already exists, you are done with C++ — `AutoModel::_shared_load_backend` +resolves the id, checks the traits, builds your backend and points `lm_engine` at +its engine. No frontend change. + +For a new family, add `modeling_.{hpp,cpp}` under `AutoModel/` and wire it +into [`all_models.hpp`](../../include/AutoModel/all_models.hpp) — the enum, the +`modelFamilyMap` entry, and the `switch` case. Keep it backend-agnostic: +[`modeling_phi4.cpp`](../AutoModel/modeling_phi4.cpp) has no `#if +FLM_ENABLE_CORELIB_AIE4` anywhere. It loads the backend, sets up the tokenizer +(honouring `backend_->forced_eos_ids()`), applies the sampler, and delegates the +decode loop to `_shared_generate`. + +Also register the FLM-side engine if the family has one: +`RegisterFlmNpu<_npu>(registry, "")`. + +--- + +## 6. The catalog + +Two files, and both must agree. + +**[`model_list.json`](../../model_list.json)** — the entry.

The downloader refuses anything it cannot match +([`model_downloader.cpp:46`](../../pull/model_downloader.cpp#L46)). + +--- + +## 7. Tests + +Three tiers, and the first two do not need an NPU: + +- **Pure logic** — the GGUF and host layers.

The stub repeats the real backend's + pre-device work verbatim, which keeps the "nothing is opened before validation" + and "no device is created for a bad package" assertions meaningful. +- **Registry and selection** — [`test/model_backend/`](../../test/model_backend/), + Linux-buildable: registration, duplicate ids, resolution precedence, and the + error text for an unregistered or disallowed id. + +Add a `test/_corelib_aie4/` directory following the Phi-4 one. Note the +trick it uses at configure time: it synthesizes a version-bumped copy of +`ryzenai/corelib.h` and asserts the adapter **fails** to compile against it, which +is how the 0.3.0 pin is actually enforced. + +--- + +## 8. Verify + +```powershell +flm pull : +flm run : --backend corelib_aie4_gguf +flm run : --backend bogus # must exit 1, listing the real ids +``` + +Check, in order: + +1. `show_profile` prints `Backend: corelib_aie4_gguf` and a `Backend detail:` line + with the loaded corelib path. +2.

Pass it down instead. load_model reads it once and hands the parse to both _shared_load_backend and setup_tokenizer, so the directory layout stays the frontend's knowledge: a backend is a pluggable lower layer and should be given what it needs rather than knowing which file to open. That also drops a filesystem dependency from the backend, and it scales -- a second backend needing the same file would otherwise have copied the read a third time. Cross-validation is unaffected. ValidatePhi4Contract draws its independence from comparing two different sources, the GGUF metadata against the shipped config, not from which layer called open. The test stub mirrors the real backend by construction, so it takes the parse from the context too. Also stop the test harness exiting on the first failure. RunTest called exit(1), so a suite with four broken tests reported one and each fix merely uncovered the next -- which is how three of these stayed hidden. It now counts failures, reports them all, and forces a nonzero exit from atexit because every main here ends with an unconditional PASS.

The one that matters is the decode cap: the loop tested it in the `while` condition, so running out of window left `reason` at its EOT_DETECTED default and the caller was told the model had chosen to stop. That is what becomes `done_reason` over the API, so a truncated reply was indistinguishable from a complete one. The cap is now an explicit break that records MAX_LENGTH_REACHED, and the two early returns -- EOS, and already at the cap on entry -- assign the reason they had computed but were dropping. A poisoned model also described itself two ways: the request that broke it got "unload/reload is required", every later one got "the model must be reloaded" from the shared guard. Same condition, same words now, keeping the backend id the guard usefully added. The cancellation test asserted a poll count, which only held for the old loop shape: it cancelled after a fixed number of predicate calls, so a loop that consults the predicate once per iteration instead of twice "failed" it while behaving correctly. It now cancels once a decode step has actually run and still requires that no further forward is dispatched, which is the property worth holding and does not depend on polling cadence.

The creates are independent -- each reads its own mapped range of the GGUF and produces its own object -- so they now run across a pool of 8 rather than in sequence. The per-create thread hint goes back to corelib's default of one. The parallelism is real threads we own, which also means it is not subject to whatever thread limits the surrounding environment imposes on the packer; a session that had the packer pinned to one thread was paying 30 s where the same binary took 3 s elsewhere. Order of completion is no longer defined, so the tests that indexed the create log positionally now look creates up by the mapped address they packed from. That is the stronger assertion anyway: the lookup requires exactly one match, so it proves each weight was packed from its own range exactly once, which positional indexing never did. The fake corelib held its state mutex for the whole of every entry point, so creates serialised inside it however many threads called in -- the concurrency could not be observed and would not have been exercised. It now steps outside the lock for a short packing window, which is what a real create does, and the engine test requires the observed peak to be above one and within the budget.

Three entry points are added to the API table for it: weights_copy_data and the two ..._weights_create_from_file. All 161 blobs go in one file with a JSON index beside it, written last and renamed into place so a data file without a matching index is never used. Both directions walk the same slot order, so an index entry always refers to the weight it was written from; the creates complete out of order but are assigned by slot, not by completion. The cache is keyed on the GGUF's size and write time, the corelib version, the group size and the weight count. Not on the GGUF's content: hashing 4 GB costs more than the packing the cache exists to avoid, which would defeat it. That trade is safe to make here because corelib independently rejects a slice whose length is not exactly what the descriptor packs to, so a stale-but-plausible cache cannot quietly become the wrong weights. A miss, a stale key, an unreadable index or a failed bind all fall back to packing; a partial bind releases everything rather than leaving half a model. FLM_AIE4_WEIGHT_CACHE redirects the cache or, set to 0, disables it. The engine tests disable it: a cache written by one test would otherwise make every later one load instead of pack, and the packing assertions would quietly stop testing anything. Whether this is faster than packing is a measurement, not yet a claim -- corelib's own guidance is that caching only pays for a large blob. The load profile reports which path ran and what writing the cache cost.

Two gigabytes stayed on disk in between, and stayed indefinitely if that write never happened -- a failed pack, a read-only directory, a machine that never loads the model again. It is now deleted at the point it is known to be useless, before repacking, together with the temporaries an interrupted write leaves behind. The load profile says how much was reclaimed. Failing to delete is not a reason to fail a load, so this is best effort like the rest of the cache.

Neither said the one thing a caller needs, which is the NPU generation. A family has at most one engine per generation, so the generation is the only axis of choice there ever was. So the backend id is now the platform id: `aie2p` and `aie4`, the same strings `model_list.json` already uses for `supported_platforms`, and the same string `build_npu_platform()` returns. `resolve_backend_id` no longer translates between two vocabularies. The tree follows the names: `common/corelib/` and `include/corelib/` become `aie4/`, `models/phi4/flm/` becomes `phi4/aie2p/`, `models/phi4/corelib/phi4_corelib_*` becomes `phi4/aie4/phi4_aie4_*`, and the test suite `phi4_corelib_aie4/` becomes `phi4_aie4/`. Class `phi4_corelib_aie4` is `phi4_aie4`, and `CorelibProcessGuard` is `Aie4ProcessGuard`. The build option `FLM_ENABLE_CORELIB_AIE4` becomes `FLM_ENABLE_AIE4` for the same reason: it selects a generation, not a library. It is also now the only thing that selects one, so its name should say so. `acquire_npu_device()` becomes `open_npu_device()`, which is what it does. No behaviour changes. The files under `aie4/` that wrap corelib's C API keep their `corelib_` names, because there the vendor library is the subject.
