🚨 MiniMax opened the weights for M3.1 Flash today. It's 428B parameters with only 23B active per token, and MiniMax reports 73.7% on DeepSWE v1.1 and 61.7 on OSWorld V2. MiniMax says an earlier version ran anonymously as "Space Bunny" and pushed 200T+ tokens before anyone knew whose it was. Together AI, SGLang and NVIDIA NeMo had day-0 support, so you can serve or fine-tune it right now. Every open release at this level makes closed-model pricing harder to defend.
