Analysis
This post discusses the initial experiences of a user testing Xiaomi's MiMo v2 Flash, a 309B MoE model claiming Claude Sonnet 4.5 level coding abilities at a fraction of the cost. The user found the documentation, primarily in Chinese, difficult to navigate even with translation. Integration with common coding tools was lacking, requiring a workaround using VSCode Copilot and OpenRouter. While the speed was impressive, the code quality was inconsistent, raising concerns about potential overpromising and eval optimization. The user's experience highlights the gap between claimed performance and real-world usability, particularly regarding documentation and tool integration.
Key Takeaways
- •MiMo v2 Flash claims Claude-level coding at a significantly lower cost.
- •Documentation is primarily in Chinese and difficult to navigate.
- •Integration with common coding tools is lacking, requiring workarounds.
