## Summary

Intern-Decision-4B is a multimodal structured decision model fine‑tuned from Qwen3.5‑4B. It takes a shared state, a schema of named questions and optional images, and returns an answer distribution for each question in a single forward pass. The model maps options to single‑token symbols, reads logits before each placeholder, applies a softmax over allowed symbols and uses the checkpoint’s probability calibration. The default temperature is 1.992418, fitted on 1,728 calibration cases and 1,693 validation cases.

The released code provides a DecisionEngine class for Python 3.12+, loading the model on CUDA and handling image resizing. Requests may contain up to 16 questions, 62 options per question, and eight images, with a token limit of 8,192. Latency numbers are measured on a single RTX 4090 but not disclosed. The model’s license follows the original Qwen terms, and the weights are available via Hugging Face under the internlm/Intern-Decision‑4B repository.

## Key points

- Intern-Decision-4B is fine‑tuned from Qwen3.5‑4B and supports text and image inputs
- Accepts up to 16 questions, 62 options each, and eight images per request, with an 8,192 token limit
- Default temperature 1.992418 was fitted on 1,728 calibration cases and 1,693 validation cases

## Why it matters

The model enables developers to embed structured decision‑making directly into applications, cutting latency by avoiding free‑form generation and providing calibrated probability outputs for business workflows.
