MiniMax M4
MiniMax's M3 landed June 1 and reset the open-weight bar: frontier coding (59.0% SWE-Bench Pro — above GPT-5.5 and Gemini 3.1 Pro), a 1M-token context window and native image + video understanding in one architecture. The company has publicly committed to a new M generation in the second half of 2026 — M3.5 or M4, the watch is the same. The second it answers, ArtificialWatch fires.
