MiniMax has released the open weights for M3.1 Flash—the model previously teased as "Space Bunny"—on Hugging Face and ModelScope. It's a mixture-of-experts model with 428B total parameters and 23B active per token. MiniMax reports 73.7% on DeepSWE v1.1 and 61.7 on OSWorld V2, and SGLang plus hosts like Together AI had it running on day one.
The replug adds that his book walks through the PyTorch fundamentals underneath models like this, step by step.
