Overview
Xiaomi MiMo Open Platform is the official large model API platform launched by Xiaomi on March 18, 2026, uniformly hosting 8 models from the MiMo-V2 / V2.5 series. On April 28, Xiaomi announced that its flagship large model MiMo-V2.5-Pro and the full-modal MiMo-V2.5 series are fully open-sourced (MIT license), making it the first mobile phone manufacturer to top the global open-source large model leaderboard. On May 27, the API permanently reduced prices by 99% (cache hit input), simultaneously launching the Orbit incentive plan with 100 trillion tokens.
**Two recent major events further amplified its presence**: **On June 11, Luo Fuli's team open-sourced the terminal programming Agent「MiMo Code」** (developed by 5 people in 14 days, based on OpenCode, topping GitHub Trending on the first day of open-source, with Stars quickly exceeding 9000+), positioning MiMo-V2.5-Pro as the 'domestic open-source version of Claude Code'; **On June 9, in collaboration with TileRT, MiMo-V2.5-Pro-UltraSpeed was launched**, the world's first model to achieve a decoding speed of 1000+ tokens/s at the trillion-parameter scale. **Important reminder: The old versions MiMo-V2-Pro/Omni were taken offline on June 30**, with automatic routing migration to MiMo-V2.5-Pro/Omni (using V2.5 pricing), and MiMo-V2-TTS is simultaneously routed to V2.5-TTS. Developers need to pay attention to interface migration.
Key Features
- Full MIT License Open Source: 8 models including Pro/Omni/TTS/ASR have full weights open-sourced on Hugging Face, supporting commercial use and secondary training
- Token Efficiency +42%: Compared to similar models, the number of tokens required for the same output is nearly halved, directly cutting Agent task costs in half
- First to Adapt 7 Domestic Chips: Covers almost all domestic inference chip platforms, friendly for domestic substitution
- Pure Browser Architecture: MiMo-V2 series natively designed for browser use, no App binding required
- 100 Trillion Token Incentive Plan: Orbit plan provides free computing power to developers to support innovation
- MiMo Code Terminal Programming Agent (New): Open-sourced on June 11, built by 5 people in 14 days, based on OpenCode, with MiMo-V2.5-Pro outperforming Claude Code+Sonnet 4.6 on three benchmarks
- UltraSpeed Extreme Inference (New): Released on June 9 in collaboration with TileRT, achieving a decoding speed of 1000+ tokens/s at the trillion-parameter scale, the world's first model at this scale and speed
Use Cases
- Agent application development requiring long context and high cost-effectiveness
- Domestic large model substitution (finance, government, education, etc.)
- Pairing with third-party Agent frameworks like Claude Code/OpenClaw for programming workflows
- Multimodal applications (unified processing of images, video, audio, text)
Pros
- MIT license is the most permissive open-source license on the market, with zero barriers to commercial use
- After a permanent 99% price reduction, it is one of the cheapest flagship models globally
- Most complete adaptation for domestic chips, hassle-free local deployment
- Lei Jun's commitment of 60 billion AI investment over three years ensures long-term sustainability
Pricing
Pro ≤256K: Input $1.00/M, Output $3.00/M; Pro ≤1M: Input $2.00/M, Output $6.00/M. Omni ≤256K: Input $0.40/M, Output $2.00/M. TTS is free for a limited time. New users receive ¥10 trial credit upon registration, and participating in the Orbit plan can earn millions of token quotas. **Note**: Old versions MiMo-V2-Pro/Omni were taken offline on June 30, uniformly routed under V2.5 series pricing.
Summary
Xiaomi MiMo is the most noteworthy new force in the 2026 domestic open-source large model camp—'topping open-source + MIT license + permanent price reduction + domestic chip adaptation' all done together, with a very clear positioning. In June, it further gained attention twice with MiMo Code (terminal programming Agent) and UltraSpeed (1000+ tokens/s extreme inference), solidifying its differentiation label of 'cost-effectiveness + extreme engineering.' Suitable for budget-sensitive Agent developers, enterprises needing domestic solutions, and teams wanting a programming flagship but put off by Claude Opus's price.
