Intern-Decision-4B is a multimodal structured decision model fine-tuned from Qwen3.5-4B. It accepts a shared state, a schema of named questions, and optional images, and returns an answer distribution for every question in one model forward pass.

How inference works

1. Preserve the question and option order, and map each question's options to single-token symbols A, B, …, Z, a, …, z, 0, …, 9.
2. Render the original system prompt, state, decision schema, and a complete assistant JSON skeleton with one <decision> placeholder per field. Preserve the checkpoint's chat template and empty thinking block.
3. Run one causal Hugging Face forward pass. For the masked-next-token decision objective, read logits at the position immediately before each placeholder.
4. Take a softmax over only that field's allowed candidate-symbol logits, then apply the checkpoint's probability calibration.
5. Map symbols back to the original option values and return typed JSON answers.

This API performs structured candidate scoring. It does not call generate() or sample free-form text. A request can contain multiple fields; no gold answers are inserted into the prompt. The inference compiler uses only state, questions, and optional images.
