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.
