Key points

  • MCR is a closed-loop multimodal reasoning formulation that integrates observation, reasoning, tool actions, feedback, and memory into a shared evolving context.
  • M2LA, or Multimodal Multi-head Latent Attention, compresses the KV cache to make long multimodal rollouts efficient.
  • The staged training pipeline includes M2LA conversion, continued pretraining, short-to-long video SFT, verifiable-task RL, and on-policy distillation.
  • It shows substantial gains over InternVideo2.5-7B on long-video benchmarks such as Video-MME, MLVU, and EgoSchema.
  • It instantiates a video agent with retrieval and verification tools to demonstrate the practicality of recursive multimodal reasoning.
  • Because the open-weight ecosystem is evolving rapidly, the paper emphasizes the principled value of context efficiency and closed-loop reasoning over state-of-the-art claims.
