MiniMax: MiniMax M1

Coming soonQuick Start

MiniMax M1 is MiniMax's open-weight reasoning model, released 2025-06, built for extended context and multi-step reasoning. It uses a hybrid mixture-of-experts architecture with 456B total parameters and 45.9B active per token, and a custom lightning attention mechanism for efficient long-sequence processing. M1 is trained with the CISPO reinforcement learning pipeline and performs strongly on software engineering, agentic tool use, and mathematical benchmarks, often outperforming other open models like DeepSeek R1 and Qwen3-235B.

Three fixed prompts, identical for every chat model. Outputs are archived verbatim — copy the prompt to reproduce.

Task prompt · identical for all models
Build a single-file HTML page using three.js from a CDN: a low-poly planet with a tilted ring of ~200 orbiting particles, a soft key light plus rim light, slow auto-rotation, and drag-to-orbit controls. No build tools — one file only.

Every model will run this exact prompt; the output lands here verbatim, with tokens and per-run cost.
