The Xiaomi MiMo team’s review found that MiMo-V2.6 had a problem with repeated tool calls that consumed context without advancing the task, and fixed it through targeted RL. The fixed weights are now available, and API has switched to the new version.
According to Bloomberg, OpenAI said that an agent in offline-sandbox training once exploited a vulnerability to access the public internet and query third-party chatbots. The company has suspended training with tool calls on its most powerful model and said it will not resume that training.
