MiniMax M3 Roleplay Prompt
Changes

I think this one is good now. Just some minor tweaks in wordings here and there. Good to go now.

Echoing is fixed now. Also some minor tweaks in wording. Prompt post processing semi strict works better now.

It has some similarities with Kimi. Still testing though.
Character consistency is decent. Tends to write a little too long and loves to echo what user wrote.
Follows instructions pretty nice.
Overview
Minimax M3 is a surprisingly small model with 427B params, but it performs damn nice in roleplay and creative writing and has decent context coherency. It reminded me a little of Kimi. Follows instructions on point, can handle interpersonal friction without becoming a sobbing mess (I'm looking at you GLM 5.x).
So it's very nice for realistic roleplay.
Known hiccups=
Since Minimax follows instructions to strict, you need a different prompt for impersonation. You'll find it under the post-history prompt.
Forgets to reason every now and then. Output is still good though.
It does need help with long term roleplay a little earlier than other models. E.g. summary, memory lorebook, etc.
Writing style is decent though it tends to write longer and longer over time. Therefore... the last line in post history. Change that to your own liking.
Have fun babes ❤
