🌟 ReVisual-R1 (7B) — Open-Source Multimodal Reasoner

One cold-start, two RL stages, endless reasoning power.

---

🔑 Highlights

• SOTA on 9 tough benchmarks covering visual–math + text reasoning.

• Three-Stage SRO Training

  1. Text Cold-Start — seed deep reflection
  2. Multimodal RL — align vision & logic
  3. Text RL — polish fluency & brevity

• PAD (Prioritized Advantage Distillation) keeps gradients alive.

• Efficient-Length Reward = concise, self-reflective CoT.
