MiniMax M3 Is Here: Open-Weight (Promised) Coding Frontier With 1M Context, Native Multimodal, and the New MSA Architecture
Analysis: MiniMax M3 launched June 1, 2026 as an API-and-agent product, promising frontier coding, up to 1M tokens of context, and native multimodal on a new sparse-attention architecture (MSA). Open weights and a technical report are promised within roughly ten days but not yet shipped, all headline benchmarks are vendor self-reported, and reported pricing varies by source — we separate what is confirmed from what is claimed.
