Story details

MiniMax announced the M3.1 Flash model for agentic tasks, coding, computer use and cybersecurity. The company says online inference is nearly three times faster and usage costs are 70% lower than its comparison baseline.

Those are company-reported comparisons; the release does not make them universal results across providers or workloads. MiniMax describes benchmark gains in several task areas, while access to model weights is announced separately. MiniMax said M3.1 Flash weights would be released later; the announcement does not make them available in this release.
