## Summary

MiniMax launched its M3.1 Flash model on October 19, 2026, making it available via its API, M Plan, and MiniMax Code desktop app. The model has 428 billion total parameters with about 23 billion active parameters in a mixture-of-experts architecture and supports a 1 million token context window. Pricing is set at $0.15 per million input tokens and $0.60 per million output tokens, with cache reads at $0.015 per million tokens. Model weights are scheduled for release on October 23, 2026, though the license has not been disclosed. MiniMax reports the model achieves a score of 62.2 on Automation-Bench v1.0.6, which it states is the top score in its internal benchmark table, while noting all performance figures are self-reported and lack independent verification.
