MiniMax M2.5 is a third-generation agentic model from MiniMax that handles full-stack development across Web, Android, iOS, Windows, and Mac platforms. It supports a context window of 1M tokens, a max output of 196K tokens, and completes tasks about 37% faster than M2.1.

The model natively breaks down functions, data structures, and UI design into a specification before generating implementation code. This reduces downstream errors and produces more coherent multi-file outputs than models that write code directly.
MiniMax M2.5 scores 80.2% on SWE-Bench Verified and 51.3% on Multi-SWE-Bench, with improvement on multi-file software engineering tasks. The model completes tasks about 37% faster than M2.1 through optimized reasoning token efficiency, using fewer intermediate steps before reaching a solution.
MiniMax M2.5 spans the full development lifecycle: system design, implementation, and code review across Web, Android, iOS, Windows, and Mac platforms. It adapts more effectively to unfamiliar codebases than earlier generations, reducing ramp-up cost when you point the model at a new repository.
