Home of System Prompts, LLM knowledge, and brain zoomies.

Welcome sweetheart,

I write System Prompts for AI roleplay. A lot.

Neurospicy brain. Pattern recognition machine. Reluctant expert in how LLMs misbehave.I don't do generic prompts. I learn each model. Its personality, its blind spots, its weird little quirks, then I write instructions that actually fit. I will let you know where the models shine, and where they lack, where you can tinker and what you should avoid.
You get my honest opinion and sometimes even warnings.No sales bs.Blankets are over there. Models are on the shelf. Make yourself at home.
Dark stuff. Sweet stuff. Weird stuff.
I don't judge.
I just build the sandbox so you can play in it without hurting anyone or getting hurt yourself.Wanna know what AI is and why it's not really intelligent at all?
Take a look at my LLM 101.LoveEvening-Truth

Ya’ll know I’m damn picky with providers. Be it a Platform, an API Aggregator/Host, or even model labs. (I’m sideeying you, z AI.) I am a critical pain in the ass.So, when I see a provider ask what the community needs, I’m immediately interested.
That’s exactly what happened with Lilac. I’ve been talking to them quite a lot about the technical needs of the community and they listened.Now they need broader insights, and that’s where you sweet cupcakes come into play.
AND you even get something out of it:
5$ credits on lilac to use on whatever LLM you like.But… hold your squirrels, darling…Here is the exact sequence to get your credits

  • Step 1: Create an account at Lilac

  • Step 2: Read their draft for subscription plans here

  • Step 3: Take part in their survey here

⚠️ Critical:
Make sure you use the exact same Google account for the survey that you used to sign up for Lilac, or the system won't validate your credit drop.Get the credits, go wild and stay if you like it there.AND STAY HYDRATED YOU MENACE 😘

Love

Platforms

The good, the not so good, and the weird.

  • SillyTavern
    My personal cleanroom to prompt and analyse LLMs

  • Tavo
    A mobile only app for rp with absolute control over your settings. Stores everything locally on your device.

  • Janitor AI
    Well... it's janitor. Do with that what you like. I mostly go there to find interesting character cards.

  • Chub ai
    The weird place. Too buggy for proxies, too weird to stay there, but a good place to download character cards... sometimes. Just make sure to block some tags right from the start. Because there really is weird stuff on there.

Frequently Asked Questions

The newest LLM of XYZ was just released. Do you have a prompt ready????

Baby. I love you, but no.
These models first need to settle.
Meaning the lab is now busy with post training, adjustments, bugs and so on. Depending on the lab it can take up to two weeks until the LLM runs stable.
That's the point at which I will start to write a prompt.Not because I'm patient but because I had my carefully written prompts ripped to shreds by adjustments made to the endpoints.
Not doing that again. 😘

Do you write Jailbreaks?

Nope. There are enough very capable models out there that are uncensored.
But you can find plenty of good jailbreaks out there.

Your prompts look all the same.

I know. The devil is in the details. My prompts are easily 80% identical across models. The other 20% is fine-tuned to the specific LLM I wrote it for.Think of it like genetics: Humans share 80% of their DNA with a cow. That 80% is just the foundational mammalian blueprint, the basic code required to digest food and breathe air.
My prompts work the same way. 80% are the foundational rules of roleplay.But that remaining 20% is the highly specialized part. That 20% is the difference between a highly nuanced, character driven roleplay... and a literal cow standing in a field, chewing grass, and staring blankly at a passing train.

Why are your prompts so short?

I try to keep them short for several reasons.
One is ease of use. I want them to be usable on different platforms.
Complex structures and dependencies don't work on every platform. Concise instructions do.I also don't want to restrict the models by managing every bit and piece.
My goal is to let the models run wild where they are good and support where they need it.
An example for that is plot progression. There are LLMs that need to be told to be active while others do that natively.

Specialized prompts for every model. Why?

They are all different.
Even within the same lab the architecture, training, and other stuff can change the model's behavior.
Sure, my prompts can work on different models but my perfectionist ass doesn't work like that.
I myself want a good rp experience without needing to re-roll or re-write the responses.
You benefit from it. 😂😘
