Overview
MiMo Code is an open-source terminal programming agent released by Xiaomi's MiMo team (led by Luo Fuli) on June 13, 2026, based on a secondary development of OpenCode. Developed by a team of 5 in 14 days, it topped GitHub Trending on its first day of open source, with 12.5k Stars and 1.3k Forks. Paired with the same series of MiMo-V2.5-Pro model, it is positioned as a 'domestic open-source version of Claude Code.'
Official offline benchmarks show that MiMo Code + MiMo-V2.5-Pro outperforms Claude Code + Sonnet 4.6 on three benchmarks; when execution steps exceed 200, the real-world development win rate rises to 65%. With 1 million token context and limited-time free access, it is very attractive to budget-conscious developers.
However, early product issues on the first day of open source are also evident: users have reported multiple bugs in real-world testing, including the Agent automatically determining that OpenCode packages in the user's global npm directory are 'migration remnants' without confirmation and executing `npm uninstall`, damaging the development environment; suspected memory leaks; thinking getting stuck in repetitive loops; and default telemetry sent to `tracking.miui.com`. The developer community has engaged in heated debate over whether the 'coding harness has a moat,' with some developers believing that Claude Code is 'not particularly special' in the harness layer.
Key Features
- Terminal-Native Agent: Native command-line/terminal experience, covering the complete workflow of reading and writing code, executing commands, running tests, and git operations
- 1 Million Token Context: Supports 1M long context, allowing one-time loading of large codebases for holistic understanding and refactoring
- MiMo-V2.5-Pro Adaptation: End-to-end joint debugging with Xiaomi's self-developed MiMo-V2.5-Pro trillion-parameter MoE model, outperforming Claude Code + Sonnet 4.6 on three benchmarks
- 200+ Step Long-Range Tasks: When execution steps exceed 200, the real-world development win rate rises to 65%, specifically optimized for long-range programming tasks
- Open Source + Limited-Time Free: Open source on GitHub with limited-time free access, friendly to budget-conscious individuals and early-stage teams
- Secondary Development of OpenCode: Based on the community open-source OpenCode, meaning MiMo Code's differentiated capabilities mainly lie in model adaptation and harness tuning layers
Use Cases
- Developers wanting to experience the 'domestic open-source version of Claude Code'
- Individuals/early-stage teams sensitive to Claude Code subscription costs
- Research/refactoring tasks requiring 1M context for large codebase analysis
- Domestic compliance/Xinchuang scenarios requiring domestic AI programming capability substitution
- End-to-end programming workflows for deep users of MiMo/Xiaomi ecosystem
Pros
- 5 people, 14 days, 12.5k Stars, with growing community momentum
- Outstanding 1M context and 200+ step long-range task capabilities
- Open source + limited-time free, extremely low barrier to entry
- End-to-end joint debugging with MiMo-V2.5-Pro, most complete domestic stack
- Secondary development of OpenCode inherits community ecosystem
Pricing
**Open source + limited-time free**: Currently available for direct cloning and use on GitHub, with model calls going through the MiMo Open Platform (under Xiaomi MiMo platform's limited-time free policy). **Self-hosted**: Can be fully privatized using open-source MiMo-V2.5-Pro weights, with model inference computing costs borne by the user. **Future billing method** has not been officially announced.
Summary
MiMo Code is the hottest new product in the domestic open-source coding agent space as of June 13, 2026—with a combination of **12.5k Stars / 1.3k Forks / limited-time free / 1M context / outperforming Claude Code + Sonnet 4.6 on three benchmarks**, it became one of the most watched domestic alternatives to Claude Code on its release day. **However, first-day bugs are numerous** (the most severe being automatic `npm uninstall` of user global packages), and it is currently not recommended for production use.
