XiaomiMiMo/MiMo-Code v0.1.7

on GitHub

Summary

This release adds tool_script — programmatic tool orchestration in a QuickJS sandbox, letting the model chain multiple tool calls in one script instead of many round-trips, with a hardened serialization contract, sandbox jail, MCP dispatch, and opt-in gating.

It also introduces session handoff + a try-best detector (behind MIMOCODE_ENABLE_TRY_BEST_HANDOFF, default off) and a big skills push: new bundles (data-analytics, product-design, sales, learn-everything), a skill_search tool with BM25 matching, bundle autocomplete + i18n, and the mimocode bundle renamed to mimocode-docs. Other updates: xAI/Grok bump with OAuth login, interleaved-reasoning transform sync, several provider/session robustness fixes, and switching install docs to bun ci.

本次发布新增 tool_script:在 QuickJS 沙箱里以脚本方式编排工具调用,让模型在一段脚本里串联多个工具、减少多轮往返,并配有严格的序列化契约、沙箱隔离、MCP 分发和按需开关。

同时引入会话交接(handoff)+ try-best 检测器(由 MIMOCODE_ENABLE_TRY_BEST_HANDOFF 控制,默认关闭),以及一批技能(skill)增强:新增 data-analytics、product-design、sales、learn-everything 等 bundle,带 BM25 匹配的 skill_search 工具,bundle 自动补全与多语言,并把 mimocode bundle 更名为 mimocode-docs。其他更新:xAI/Grok 升级并支持 OAuth 登录、interleaved reasoning 的 transform 同步、若干 provider/session 健壮性修复,以及安装文档改用 bun ci。
