similarly for me, MiniMax is kind of horrible that it somewhat regularly fall into loops that I had to save it from. DeepSeek & MiMO rarely got stuck. wonder how you get completely reversed experience.
I did develop my own agent around MiniMax. I did see weird behavior when I messed up the loop, like omitting pieces of remove thinking; maybe it's an agent bug, some models/providers just ignore/normalize the broken input, some don't.
Seems like the harness may have to be "finetuned" for models. I've had my share of MiMo 2.5 Pro get stuck in thinking loops with GitHub Copilot.
