InternLM open-sources Intern-Decision 4B/0.8B: structured decisions in one forward pass
jacek2023 · reddit · 2026-09-26
internlm released Intern-Decision-4B and 0.8B, open multimodal structured decision models fine-tuned from Qwen3.5. They take a shared state, a schema of named questions and optional images, and return an answer distribution for every question in a single forward pass.
Options are mapped to single-token symbols (A, B, …), the prompt includes a full JSON skeleton with per-field placeholders, and logits are read immediately before each placeholder, softmaxed over only that field's candidates, calibrated, and mapped back to typed JSON. No generate() or free-form sampling — pure structured candidate scoring. Demo, weights and GitHub repo are available.
