100 coding environments: MiniMax M3.1 Flash priced like MiMo V2.6 Flash but weaker
Across 100 coding environments, M3.1 Flash lands at similar pricing to MiMo V2.6 Flash with lower performance, and the author says it is far from the Pareto front for open-weight or proprietary models.
We evaluated Kimi K3.1 Pro and Minimax 3.1 Flash across 100 coding environments. Overall Kimi K3.1 Pro is not an upgrade in overall intelligence (better in fluid intelligence, worse than K3 in long horizon agentic coding) -- within margin of error of the previous release, but it achieved that similar performance with far fewer reasoning tokens at the same effort level, which combined with the new pricing leading to a 60%+ price reduction! However, MiMo V2.6 Pro is still the most cost competitive open weights model at a comparable intelligence today. This is a promising direction for Kimi, as they basically approached the reasoning length problem like Ember-1/Fireworks, but they did so without much of a performance hit (performance is roughly neutral/within margin of error of Kimi K3 at a significant price/speed boost). For Minimax M3.1 Flash, it ends up pricing similarly to MiMo V2.6 Flash, but at lower performance. It would have been a strong release 3 months ago, but today it's nowhere near the Pareto front for open weight or proprietary models.
