Merge Risk: 🟡 Moderate · up to The PR adds standalone embedding routing and runtime behavior, but valid embedding checkpoints may be rejected by the family configuration path, and the new runtime headers may cause build or linkage failures.

Full details: Docstring CoverageExplanation Docstring coverage is 30.21% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 235 functions across 38 files. (4 skipped: 4 unsupported.) Full details: Description checkExplanation The description covers the required sections and validation evidence, but it describes a different implementation. It states that the existing qwen family owns embedding support, while this pull request adds a standalone qwen3_embedding family with separate Python, C++, and E2E components. Resolution Rewrite the description to match the current changeset. Describe the standalone qwen3_embedding family, its plugin, checkpoint mapper, engine builder, runtime pipeline, and E2E coverage. Update the validation and risk statements to reflect the actual files, objectives, and remaining qualification gaps. Comment |

The implementation looks pretty good. However, one suggestion is that we should make the Qwen3-Embedding into its own family, so that we don't dynamically switch the runtime strategy in the same plugin. Doing so increases coupling and causes long-term system instability. Just ask your agent to refactor this out to its own family. An internal CI has passed. Once the refactor is done, we can merge it in. |

Refactor complete. Qwen3-Embedding now owns separate Python, C++ runtime, and E2E family trees, while the existing Qwen plugin remains generation-only. Family selection is checkpoint-scoped through the Sentence Transformers pooling metadata, so there is no dynamic runtime-strategy switching in the Qwen plugin anymore. The local ownership, isolation, catalog, static architecture, and embedding contract checks pass; current-head CI is running now. |

The refactor is complete and the current-head Community CPU Required gate is now green, including the full source-only C++ and Python unit job. The PR remains draft because the pre-refactor internal result does not cover this standalone-family revision. Could you retrigger internal CI for the refactored branch when convenient? |

Two copies of acceptance math can diverge, and a threshold change in one path will not apply to the other.Extract one helper that both call, so the contract and the comparator report identical metrics.
Two behavioral differences also exist between the copies and look unintended:
- This file adds the zero-norm guard on Lines 55-60. The comparator has no equivalent guard.
- This file uses the string literals
"error","passed", and"failed". The comparator usesStageStatusmembers. UseStageStatushere so a future enum value change cannot desynchronize the reported status.🤖 Prompt for AI Agents

- Line 36: Update the configuration handling around _qwen3_embedding_contract so
config.raw remains JSON-serializable, replacing the Qwen3EmbeddingContract
object with primitive serialized fields or storing it outside config.raw.
Preserve the contract’s runtime behavior while ensuring
make_runtime_config_json(None) can serialize the copied configuration.
In `@src/runtime/models/qwen3_embedding/plugin_helpers.cpp`:
- Around line 395-406: Harden write_kernel_so_to_temp by sanitizing global_name
to allow only expected filename characters, rejecting path separators, traversal
components, and other unexpected input before constructing the /tmp path. Check
the output stream after opening and writing, and fail explicitly instead of
returning tmp_path when the file cannot be created or the write is incomplete,
so load_tvm_ffi_module_func never loads an invalid artifact.

- Line 562: Update the docstring for the HF embedding reference function to
describe last-token pooling followed by L2 normalization, matching the
implementation that selects the last unmasked position around the existing
pooling logic.

Rebased the standalone Qwen3-Embedding family onto current main and resolved the aggregate family, performance, and validation catalog conflicts by preserving both the newly merged mainline entries and this family. Local model/catalog validation, impact validation, Ruff, focused source-only tests, and the website inventory pass. The PR is conflict-free, and current-head public CI is running.

Addressed the full review batch: runtime config now excludes private build metadata, the embedding contract remains JSON-safe, BF16 weights retain FP32 storage until the TensorRT cast, RoPE tables are vectorized, temporary kernel artifacts are unique and checked, and the default pooling path has regression coverage. I also pruned the unused family-private C++ helper surface. ModelConfig remains family-local intentionally to preserve model isolation. Focused validation: builder tests 8 passed / 2 skipped, embedding contract tests 13 passed / 1 skipped, Ruff clean, and diff check clean. |

Addressed the normalization dtype boundary described above in a75c154. Added source-only strongly typed graph tests for BF16/FP16/FP32 across the three helpers. Before the fix, all three BF16 cases failed on mixed BF16/FP32 elementwise operands; the six FP16/FP32 cases passed. After the fix:
These tests exercise dtype propagation through the real helper functions using a typed test network; they do not build a TensorRT engine. The exact requested GPU E2E has not been rerun: this test environment has no TensorRT runtime configured. The branch also still conflicts with current main and needs migration of its builder, bundle and native factory to the post-cutover family/Task interfaces. I am not treating this as GPU-qualified or requesting a rerun on the conflicting branch. One ownership question before the migration: current |

Current head: b69fda2. Merged upstream 613bbf0 while preserving published history. The qualification-config conflict is resolved by retaining both the feature exclusion and upstream MoGe exclusion; no acceptance criteria were weakened. GitHub now reports the branch mergeable. Validation on the exact committed source tree: Focused embedding/support tests: 36 passed, 1 TensorRT-dependent skip. The four non-GPU E2E helper tests also passed, including the upstream three-prefill-chunk regression. New-head Community CI is running. The previous head's GPU/internal success remains historical evidence; this merge has no new GPU result yet. The performance exclusion now avoids conflating correctness evidence with release-performance qualification. |

Background
Add Qwen3-Embedding-0.6B checkpoint support with its sentence-transformers last-token pooling and L2-normalization contract. This updates the original PR to current main: the existing Qwen family owns both generation and embedding, avoiding two families claiming the same
qwen3model type.Exit Criteria
Build a cacheless embedding bundle for the pinned 0.6B checkpoint and expose the public
text_to_embeddingSDK task.Preserve BF16 activation-dtype normalization, query/document semantics, and current Qwen generation behavior.
Pass current-head public CPU checks and the declared target-GPU BF16 E2E. The declared BF16 embedding E2E now passes on Community GPU; broader performance qualification remains separate. This PR is ready for review.
Implementation
Merged upstream
393ab02f18e579101663c154fb78e77030d6be97, preserving the existing branch history. Current head:ff9ddac5555af9ab3abce62315a87f674bba40bc. Follow-up enables the BF16 embedding case in Community GPU selection and builds its public SDK consumer from the native CMake tree, rather than expecting an executable in the isolated runtime library directory.The implementation is owned by
families/qwen/: lightweight discovery selects embedding for Qwen3 sentence-transformers snapshots, then the builder verifies the precise 0.6B dimensions, Pooling/Normalize sidecars, and supported request options. FP16/BF16, single-device, one-text requests are supported; quantization, parallelism, dynamic KV, and FP32 builds are rejected before weight loading. The safetensors mapper omits the generation head.The bundle uses the existing
qwenfamily andembeddingtask, withengine.plan,runtime.json, and tokenizer sections. The native factory loads a cacheless pipeline that implementsIModeland registersITextToEmbedding; it appends EOS when missing, rejects inputs beyond engine capacity, pools the last token, and normalizes the vector. Query role applies the default retrieval instruction; Document/Default pass text unchanged. No shared API or ABI changes.The pinned family E2E builds the bundle, runs a public-SDK consumer, and compares it with Transformers using the original cosine >= 0.99, L2 <= 0.1 and norm-error <= 0.001 gates. The release catalog explicitly records missing performance qualification.

The selected embedding E2E builds the TensorRT bundle, invokes the public SDK consumer, and checks 1024-dimensional output against the BF16 Transformers reference with cosine >= 0.99, L2 <= 0.1, and norm error <= 0.001. The log records TensorRT 11.1.0 / NVIDIA container release 26.07. Family CPU checks also passed (45 Python, 4 C++); cleanup succeeded. Aggregate pytest output is 8 passed / 8 skipped, but the runner separately verified all five requested E2Es executed without skips.This closes the declared single-case BF16 GPU parity gap; it is not broad embedding-quality, FP16, performance, or release qualification. No measured cosine/L2 values are claimed because the published log records pass/fail rather than vector metrics. Performance and broader input/configuration coverage remain unverified, and the release catalog remains unqualified. No Internal CI premerge result or maintainer approval is claimed. Earlier GPU attempts that skipped embedding or failed during infrastructure setup are historical and are not used as model evidence.
Contributor Self-Review
Compared the original contract/graph/runtime with the migrated paths, retained normalization tests, verified single family ownership, and checked the public SDK's model-registration requirement.
Notes For Future Readers
Start with
embedding.py,support.py, and the runtime factory/pipeline, then the CPU contracts and E2E. Generation continues through its existing path. The family choice follows current single-owner discovery; maintainers can review it here without a second unconditional Qwen3 descriptor. Seefamilies/qwen/tests/EMBEDDING.mdfor build and SDK usage. The historical standalone plugin, central test registry and legacy bundle routes are not retained.Risk level
The migration changes builder/runtime integration while retaining the checkpoint graph and pooling contract. The declared BF16 GPU E2E has passed; broader performance qualification and repository-required integration approval remain outstanding.
