Space Bunny revealed as MiniMax M3.1 Flash, with always-on thinking defaulting to max
Confirms the stealth model tested blind in September is MiniMax M3.1 Flash and flags that thinking depth is adjustable but always on and defaults to max, which could quietly raise cost on long sessions.
Space Bunny has a name now: it is MiniMax-M3.1-Flash, and it is live on MiniMax's API. The stealth model people were testing blind in September turned out to be MiniMax's new flagship flash model. It is multimodal, built for coding, and has a 1 million token context. The numbers: $0.15 per 1M input tokens and $0.60 output, with 74% on DeepSWE. Open weights land Oct 23. The interesting knob is thinking depth. You can set effort from low to max, but thinking is always on and defaults to max, so you cannot fully turn it off. The catch: it is API only until the weights drop, and always-on thinking at max default could get expensive on long sessions before you notice. Worth trying for long coding sessions once the weights land, or does always-on thinking at max default worry you about cost? https://x.com/MiniMax_AI/status/2112111925975032241 https://platform.minimax.io/docs/guides/text-generation
