Files
| File | Purpose |
|---|---|
model.onnx | INT8 dynamic quantization, deployed artifact |
model_fp32.onnx + .data | fp32 export, provenance only (not deployed) |
tokenizer.json, tokenizer_config.json | HF tokenizer |
fixture.json | Go parity-test fixture (mirrors internal/router/cluster/testdata/fixture_qwen3.json) |
Export details
- Pooling baked into the graph: attention-mask-aware last-token pooling;
output is
sentence_embedding[batch, 1024]. No L2 norm in the graph (the router's hugot pipeline applies it). - Opset 18, exported with the torch dynamo exporter.
- Quantization: INT8 dynamic, per-channel, with
down_proj(3072x1024) ando_proj(2048x1024) MatMuls kept fp32 (outlier-sensitive activations). - Parity (cosine vs sentence-transformers reference, no instruction prefix): fp32 worst 0.99985, INT8 worst 0.98311. Go-vs-Python worst 0.9808.
Versioning
The router Dockerfile pins HF_QWEN_REVISION to a commit SHA of this repo.
Revisions are immutable; pushing a new export here never changes deployed
images until the pin is bumped deliberately.
