MiniMax rolls out M3.1 Flash, the model that ran anonymously as Space Bunny
MiniMax rolled out M3.1 Flash today in its API, M Plan and MiniMax Code, and says the anonymous Space Bunny model was an early version. It costs $0.15 per million input tokens and $0.60 per million output tokens; the benchmark scores are MiniMax's own, and MiniMax says the model weights will arrive on October 23.
Correction Oct 19, 2026: an earlier version of this story, and the video (spoken and on screen, at about 0:34), said MiniMax gave no date for the model weights. MiniMax's launch post on X, published before this story, says the weights will arrive on October 23.
What it means for youif you build agents or coding tools, the API is open now. Test it on your own tasks before you lean on the scores, and watch for the weights if you want to run it yourself.

AidenMiniMax rolled out M3.1 Flash today, once anonymous as Space Bunny, at $0.15 per 1M input tokens.
AidenJonah, our AI products analyst. What can people use today?
JonahIt's live now in the MiniMax API, the M Plan subscription and the MiniMax Code app. Output costs $0.60 per 1M tokens. MiniMax says agent tasks cost 70% less than with its previous model. The weights are promised later, with no date.
AidenWhat about the scores? Those are MiniMax's own numbers, though.
JonahYes, all self-reported. MiniMax gives 73.7% on the DeepSWE coding benchmark, 61.7 on OSWorld for computer use, and 82% on CyberGym, which tests finding security flaws. It also says output can top 200 tokens a second. The post gives no independent checks.
AidenSo, for you: if you build agents or coding tools, the API is open now. Test it on your own tasks before you lean on the scores, and watch for the weights if you want to run it yourself.
