- Who it helps
- Developers who need local routing, retrieval filtering or bounded classification.
- Availability
- The 0.4B v0.2 model card lists MIT terms and files in ONNX, a portable model format. Documented dependencies include ONNX Runtime 1.23 or newer, tokenizers and NumPy. Hosting and integration remain the developer’s responsibility.
What the model produces
Use the card’s defined question and input fields. Outputs are decision probabilities. The card documents a 2,048-token limit that keeps the beginning, which matters when evidence appears late in a document.
Check the quality targets as well as memory use
The publisher reports sub-gigabyte memory in selected CPU measurements, alongside missed quality targets on some evaluations. A long candidate list still takes time to rerank. The creator index identifies related versions; they should not be treated as interchangeable checkpoints.
What you can do
- Read the evaluation shortfalls and test a fixed set containing both clear cases and ambiguous examples before choosing a threshold. Open reference ↗
Where the evidence stops
No inference was run. Scores need task-specific calibration, and the model is not an independently verified security boundary.
