Deterministic scoring and the server-side Transformers benchmark are not browser qualification. Validate the exact converted model in the target browser and device environments.

MLC availability

No validated MLC artifact is included in this publication.

Grounded inference contract

Inference requires retrieved source context. A bare question without retrieved source context is outside the trained and evaluated contract.

• Prompt contract identity: d0dcb1de0b9d601267a3cbf39420b1f0a2c5749d80b96669a2e9fcf19a280bfb
• Chat formatting: The model's native chat template is used with thinking disabled (enable_thinking=False).

System prompt (exact):

Answer only from the supplied context. Be concise. If the answer is absent from the context, respond exactly: I can't answer that from the provided context.

User template (exact):

Context:
<context>

Question:
<question>

Refusal string (exact):

I can't answer that from the provided context.

Intended use

This checkpoint is intended for research comparing training methods on the same Kanha website-derived dataset and for controlled evaluation of website question answering.

Limitations

The checkpoint can produce incorrect, incomplete, or stale answers. It may memorize training content. Review outputs, test representative failure cases, and qualify the exact runtime before any user-facing use.
