MiniMax M3
1M-context frontier model at $0.30/M tokens — cheapest big-context model on the bench.
Reference benchmarks for MiniMax M3
These are external benchmarks I pulled from the source comparison guides on agentos.guide — SWE-bench Verified, DRACO, Kilo plan rubric, build-time measurements, vendor-reported coding scores. They are not goldiebench medal scores (those come only from same-prompt one-shot creative coding tasks in the matrix). I surface them here so the spec sheet for MiniMax M3 is honest about what's measured.
What is MiniMax M3?
MiniMax M3 is the MiniMax frontier model with a 1,048,576-token context — matches GLM-5.2 and Fable 5 context window, released 2026-06-18. Tagline: 1M-context frontier model at $0.30/M tokens — cheapest big-context model on the bench.. Official source: minimax.io.
Pricing detail. MiniMax M3 is the cheapest 1M-context frontier model on the bench — roughly 1/200th the per-call cost of OpenRouter Fusion and 1/30th of Claude Opus 4.8. Designed for high-volume agent workloads where context length matters but per-call budget is tight.

What I built with MiniMax M3
Every model on Goldie Bench gets the same fixed prompt set — one shot, single HTML file out — and I score the result 0–10 inside the Agent Operating System. Here's what MiniMax M3 shipped on the bench: 47 one-shot demos across 1,048,576-token context — matches GLM-5.2 and Fable 5 of context. Of those, 47 are scored against the field with my honest 0–10 from the source guides at agentos.guide.
Strengths
- 1M token context — full repo / full deep-research corpus fits in one call
- $0.30/M input is roughly 1/30th of Opus 4.8 — built for high-volume agent loops
- Solid one-shot HTML output — clean structure on game and visual prompts
Trade-offs
- Less polished than Fusion's panel-ensembled output on the toughest deep builds
- Newer model — less community calibration vs Fable 5 / Opus 4.8
Best for
- High-volume agent workflows where per-call cost dominates
- 1M-context tasks (whole-repo refactors, deep-research synthesis)
- Drop-in cheaper alternative to GLM-5.2 with comparable 1M context
