Today Xiaomi released and open-sourced MiMo-V2.6 — the flagship multimodal model Pro, the efficient reasoning model Flash, and the ultra-fast model Pro-UltraSpeed. MiMoCode 0.1.15 follows with a number of improvements to everyday agent runs. Within a single agent step, model-emitted tool calls now go through a sequencing gate: only pure read/search tools overlap, everything else runs one after another; if a side-effecting call fails, later calls that could be affected are safely skipped. Session resume is also more dependable — recoverable provider errors back off and retry, and an interrupted session can pick up from the right recovery target, with idle subagents resumed alongside the main turn. On the input side, the Read tool can read images, audio, and video files, so multimodal agents can work with a wider range of material.
小米今日正式发布并开源 MiMo-V2.6 系列，包含全模态旗舰模型 Pro、高效推理模型 Flash 与超高速模型 Pro-UltraSpeed。MiMoCode 0.1.15 同步带来多项改进，覆盖智能体的日常运行。在同一次执行中，模型发出的多个工具调用会进入串行门禁：只读、检索类的工具仍可并行，其余调用依次执行；若带副作用的调用失败，后续可能受影响的调用会被安全跳过。会话恢复也更加可靠：可恢复的模型错误会退避重试，中断的会话能够从正确的恢复点继续，空闲的子智能体会随主会话一并恢复。在输入侧，Read 工具支持读取图像、音频与视频文件，便于全模态智能体处理更丰富的材料。
