Kimi K2.5 Thinking Base Prompt
Change Log
05.11.2026
Updated prompt for more focus on interaction in roleplay and less hyperfocus on irrelevant details.
Go ahead. Try it. 😘
The old version is still there. Just further down on the site.
INFO
They did some things to the narrative capabilities of that thing... it's impressive!
Also uncensored in NSFW stuff. Where K2 used to rush through sexy stuff K2.5 is very very detailed.
I was told there is censoring regarding non-con, underage characters and probably other NSFL topics. I didn't test any of these though...
Below you will find the updated System Prompt!
Overview
Kimi latches onto your Character Cards like a lovesick octopus. Any logic gaps or ambiguity in that will make the model stumble... hard.
Kimi loves details and it will talk about them a lot. So you have that one line in your card that mentions e.g. a random button on the characters clothes, or a personality trait other models ignored... yeah... Kimi will give it its own stage.
- Creative 8/10
- Complex Characters 10/10
- Character Consistency 11/10
- Context Coherency 8/10
- Horror, Dead Dove 10/10
- Smut, ERP, Kink 🥵/10
- Romance 9/10
Characters that have a Dead Dove topic without any redemption arc or a sliver of empathy in their description will not develop one.
So my warning about moonshot models still stands.
Warning! If you have depression, PTSD, or other problems with your mental health... Do not use Kimi-K2.5-Thinking for roleplay with sensitive dynamics!
I'm serious, love! Self care is top priority.
Tip
- Adjust the Content Rules to your preference. e.g. xyz is allowed / encouraged / forbidden
Generation Settings:
- Max Token Output: unlimited or at least 2K
- Temperature: 1.0
- Max P (Top P): 0.95
- Top K: 0/disabled (IMPORTANT!!!!)
- Penalties: disabled... all of them
- Reasoning enabled.
Why?
Moonshot did an interesting thing and hard coded these Sampler Settings. Any other values will give you an Error.
I have to say, I kinda like that. 😁 😉
