MiniMax: MiniMax M3

Not supportedQuick start

MiniMax M3 is MiniMax's multimodal foundation model, released 2026-05. It handles text, image, and video inputs with text output, and is built for long-horizon agentic work, coding, and tool use. MiniMax Sparse Attention reduces per-token compute at long context, cutting cost to roughly 1/20 of the previous generation at 1M tokens while retaining quality.

MirAPI doesn’t offer this model. The prices shown are the official list prices.

Showcase

Every chat model gets the same three fixed prompts. Outputs are archived verbatim, so you can copy a prompt and reproduce the result.

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, and its output will appear here verbatim with token counts and the cost per run.
