Model overview
**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. 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 ` ` 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`.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
