Official Minimax M3.1 Flash benchmarks!
Very impressive benchmarks, especially considering that DeepSeek 4.1 Flash is only a few days old - and yet Minimax’s new Flash model outperforms it in several key benchmarks!
tl;dr
MiniMax M3.1 Flash matches DeepSeek V4.1 Flash’s off-peak input/output pricing and halves its peak rates, but charges more for cached input and trails the latest DeepSeek in four of six comparable benchmarks.
MiniMax M3.1 Flash: Space Performance + Bunny Speed 🚀🐰 Yes, Space Bunny - which has topped global leaderboards with 200T+ tokens - was an earlier version of M3.1 Flash. 💰Redefining the performance economics of agentic AI. M3.1 Flash achieves frontier-level intelligence across key tasks such as Cowork (Automation-Bench: 62%; ALE: 30%), Coding (DeepSWE: 74%) and Visual Reasoning (BabyVision: 91%), at 1/3 the cost of M3 and 3x the speed. API pricing (flat rate): $0.15 / $0.60 per 1M input/output tokens, with cache reads at $0.015 / 1M tokens. Model weights will arrive on Oct 23.
