MiniMax M3.1 (Space Bunny Alpha) Spotted Thinking in Token-Saving Caveman Mode

crusaderky · reddit · 2026-09-24

A Reddit user noticed that MiniMax M3.1, currently live on OpenRouter and OpenCode under the codename "Space Bunny Alpha", produces chain-of-thought with the familiar style of caveman mode — terse, telegraphic reasoning used to save tokens. The user verified this by disabling and then fully uninstalling the pi-caveman plugin, confirming it's the model's own behavior. The style only affects intermediate reasoning, not final output quality.
