- #24443: MiMo reasoning models may fail in Hermes because reasoning_content is not preserved in chat history

Most members concern Xiaomi MiMo reasoning models and keeping reasoning_content in chat history, with several PRs adding MiMo to echo-back handling in the agent code. One member instead proposes Anthropic-compatible endpoint support for MiMo thinking mode, a related but separate angle.
