MiniMax M3.1-Flash Preview Spotted in MiniMax Code, M3.1 Launch Imminent

_AndrewZhao · x · 2026-09-27

• MiniMax Code's model list has quietly added M3.1-Flash-Preview, listed alongside existing MiniMax-M3, M2.7, and M2.7-highspeed, with the max reasoning tier set as default. No official announcement yet — appears to be a soft launch in-product.
• Reasoning levels now have their own menu: low / medium / high / xhigh / max.
• Quoted context suggests M3.1 is close to launch under the codename Space Bunny (the official M3-a model already returns that name, partners are testing M3.1-preview): native image + video input, DSpark speculative decoding acceleration, 1M context retained, and reasoning tiers extending to max/xhigh — possibly dropping next Wednesday.
• The Flash + max reasoning combo is read as targeting faster, cheaper everyday coding and agent workloads.
