MiniMax M2
The open-weight coding powerhouse challenging Claude Sonnet
Everyone knows Claude Sonnet is the gold standard for coding, but the API costs can be brutal for heavy autonomous loops. MiniMax M2 changes the game as the 'Claude Killer' for the open-weight world. It crushes benchmarks like SWE-bench, offering reasoning capabilities that rival proprietary giants. For developers running local agents or seeking a cheaper API alternative that doesn't sacrifice code quality, M2 is currently the undisputed champion.
Why we love it
- Rivals Claude Sonnet in coding tasks for a fraction of the cost
- Excellent for local agentic loops (e.g., with Roo Code)
- Highly efficient MoE architecture allows running on high-end consumer hardware (Mac Studio, Dual 3090s)
Things to know
- Tool calling can be strict/unclean compared to GPT-4
- General world knowledge is weaker than STEM/Coding knowledge
- Safety filters can sometimes be overly sensitive
