New stealth model 'Space Bunny' is most certainly MiniMax M3.1.
I can independently confirm that the text tokenizer perfectly matches that of the MiniMax M3. The image tokenizer seems different, likely upgraded.
A new Stealth model is being tested on OpenRouter and OpenCode: "Space-Bunny-Alpha".
When asked in Chinese, the model claims to be a MiniMax model. Might be MiniMax M3.1. I haven’t done thorough testing yet, though, so take that with a grain of salt
