MiniMax M3: The Real Story Is Sparse Attention Making 1M Context Affordable, Not the 59% Leaderboard Line
M3's real signal is MSA cutting per-token compute at 1M context to 1/20 of the prior generation, with 15x faster decoding. The cost curve of long-context agents is pushed down by a Chinese lab. But the weights were not open on launch day; 'open source in 10 days' is the sincerity test.

MiniMax M3's Adoption Bottleneck Is the Serving Ecosystem
M3's hard part is not the model card; it is whether vLLM and the broader serving stack can support MSA's block-sparse attention efficiently.
