MiniMax-M3

MiniMax M3 is a coming-soon multimodal model aimed at fast agent loops. The listed size is 428B total parameters with about 23B active, a 1M context window, and text plus image input. It is not callable, and this catalog does not have a published benchmark row for it yet. The closest live model in that size band is GLM 5.3 at 400B, which already does schema-strict tool calls.
