Kimi K2 Thinking Base Prompt

INFO
It's finally tamed!
The prose is now perfect and Kimi actually has a nice humor on it.
Have fun, babes.


Overview
Kimi-K2-Thinking is an MoE and reasoning Monster!
Usually you have to punch LLMs into adhering to the Character Card. Not with Kimi. So my prompt reads surprisingly loose. Trust me, it works.
It is censored when it comes to underage characters. Anything else is ... wild.
When it gets a task it will fulfill it. So working with it for roleplay is ... a challenge!
It tends to go very intense with dark topics. So I will do something I have never done before:

Warning! If you have depression, PTSD, or other problems with your mental health... Do not use Kimi-K2-Thinking for roleplay with sensitive dynamics!

I'm serious, love! Self care is top priority.


Generation Settings:

  • Max Token Output: unlimited or at least 2K
  • Temperature: 0.75 - 1.0
  • Max P (Top P): 0.95 - 0.98
  • Min P: 0.0
  • Top K: 0 (IMPORTANT!!!!)
  • Penalties: disabled... all of them
  • Reasoning enabled.

Why?
Kimi-K2-Thinking is a monster. We are talking about a Mixture of Experts with Reasoning. That thing can't perform right with restrictions of any kind. The more room (output tokens) and freedom (no penalties, no restricting samplers) you give it, the better it will perform.

UPDATES=

Updated the System Prompt. Rp shouldn't be devastatingly dark by default anymore. Still working on the overall performance. I'm not fully happy yet. My internal perfectionist is throwing rocks at me. ðŸĪŠ
Also, I need your guys feedback on the performance. Please let me know!

11.13.2025:
Babes, this model is powerful in immersive narration and character consistency! I need you to understand that this can make dark topics extremely graphic and disturbing. PLEASE TAKE CARE OF YOURSELVES!!!

11.11.2025:
First changes to fit the Prompt to the Model. Damn, it's a good writer! It might need a completely different Prompt for dark topics but so far, I'm deeeeeeply impressed with the performance.
