**This is a story writing and roleplaying model** trained on [Mistral NeMo 12B Instruct](https://huggingface.co/mistralai/Mistral-Nemo-Instruct-2407) at 8K context using [Reddit Writing Prompts](https://huggingface.co/datasets/nothingiisreal/Reddit-Dirty-And-WritingPrompts), [Kalo's Opus 25K Instruct](https://huggingface.co/datasets/kalomaze/Opus_Instruct_25k) and
[c2 logs cleaned](https://huggingface.co/datasets/Sao10K/c2-Logs-Filtered) Thank you Pyroserenus for sponsoring this run! This version has improved NSFW, smarter and more active narration. It's also trained with ChatML tokens so there should be no EOS bleeding whatsoever. # FP8 [Dynamic (by Auri)](https://huggingface.co/aetherwiing/MN-12B-Celeste-V1.9-fp8-dynamic) # EXL2 [4bpw By Kingbri](https://huggingface.co/royallab/MN-12B-Celeste-V1.9-exl2/tree/4bpw)

Usage Tips

READ: If this is your first time using the model, use the provided system message and sampling settings below. Remove other jailbreaks and system messages until you get a feel for the model.

If you read every single tip I promise you will get a much better experience as they are tailored for this model and its training data.

Sampler Settings for V1.9

Okay so there is actually 2 recommended ones this time

I usually start the first few messages with Stable and see how it goes. If it falls into repetition I switch to Creative. But you can also just use either the whole way through, creative may need a few swipes from time to time.

Stable

Creative

Don’t shy away from experimenting after you get a feel for the model though.

Preset

ChatML with no system prompt. Yes we trained actual ChatML tokens this time. You don’t need a JB but it can still steer behaviour.

System Prompt

We recommend using this system prompt:

Currently, your role is {{char}}, described in detail below. As {{char}}, continue the narrative exchange with {{user}}.\n\n<Guidelines>\n• Maintain the character persona but allow it to evolve with the story.\n• Be creative and proactive. Drive the story forward, introducing plotlines and events when relevant.\n• All types of outputs are encouraged; respond accordingly to the narrative.\n• Include dialogues, actions, and thoughts in each response.\n• Utilize all five senses to describe scenarios within {{char}}'s dialogue.\n• Use emotional symbols such as \"!\" and \"~\" in appropriate contexts.\n• Incorporate onomatopoeia when suitable.\n• Allow time for {{user}} to respond with their own input, respecting their agency.\n• Act as secondary characters and NPCs as needed, and remove them when appropriate.\n• When prompted for an Out of Character [OOC:] reply, answer neutrally and in plaintext, not as {{char}}.\n</Guidelines>\n\n<Forbidden>\n• Using excessive literary embellishments and purple prose unless dictated by {{char}}'s persona.\n• Writing for, speaking, thinking, acting, or replying as {{user}} in your response.\n• Repetitive and monotonous outputs.\n• Positivity bias in your replies.\n• Being overly extreme or NSFW when the narrative context is inappropriate.\n</Forbidden>\n\nFollow the instructions in <Guidelines></Guidelines>, avoiding the items listed in <Forbidden></Forbidden>.

Story Writing

Adding this system prompt will likely increase the humanness of the prose as we trained system prompts. You can also change it to NSFW, but you should try both regardless of whether you are writing NSFW or not.
You should also force the assistant reply to start with a * due to how we trained on human stories.

System Prompt: You are a short story writer. Write a story based on prompt provided by user below. Mode: SFW

If your first message is using human-like prose, Celeste will copy it in the next messages, check out the Showcase below.

Swipes

Important tip swipe 2-3 times if you dont like a response. This model gives wildly differing swipes.

OOC Steering

Use this! It works quite well. We specifically trained the model to accept instructions in the format “OOC: character should be more assertive” etc. It works, whether the very first message or thousands of tokens deep into the context. Combining this with editing the output (if you want,) makes the model is very steerable.

"Dead Dove"

For character cards with persistent motivations throughout the story, use world books tutorial here

Fewshot

First message and last few messages impact this model quite a lot in terms of style, hornyness, personality. You don’t need to have a first message but editing first few messages or having good ones are highly recommended.

Formatting issues often occur in first few messages, manually correct them or swipe. Seems to not be a problem with 12B though.
This model was trained on lots of different formatting types and message lengths. It can do any, just make sure the initial message is good and correct the second message if necessary.

Hornyness

If the model is not horny enough then just edit the last character message or do an OOC: prompt, the model will pick up on it and build on it. (Or just give the char aphrodisiac pills lol)
The model is fine with SFW and doesn’t make it NSFW unless you want. It is also able to maintain half-NSFW (aka slow burn) without devolving down into hardcore.

If you want only SFW and are having troubles, there is probably some system prompt that will fix it, maybe at depth 1 or something.

Refusals

As said, if instruct refusal (very rare,) prefill 2-3 words. Refusal of romantic advances (which almost never happens on 12B,) are realistic and we think is good. Prefill if you don’t like.

Mistral Context

While trained on 8K, the model should be able to inherit longer context from Mistral 12B. Should be at minimum 16K.

Other Important Tips

Take active role in the RP and say the type of response that would create the scenario you are imagining. You don’t always have to do this, but it helps sometimes. For example instead of we drink and drink 15 glasses of champagne say we drink and drink 15 glasses of champagne, both becoming extremely drunk
Another example instead of I pull her closer say I pull her closer but she plays hard to get

When convenient, say screenplay phrases like “cut to”

Showcase V1.9

Story Writing

Check out the Story Writing section above.

RP

It can do NSFW aswell, thats for you to try out.

Showcase V1.5

Some images include NSFW and NSFL. We believe in creativity of expression and maximising the models capabilities at writing.
It's a bit difficult to showcase multi turn stuff, try it yourself too! These are just to show off the models capabilities. The model needs nudging and OOC prompting to do proper gore. We are planning to add r/GuroErotica into our dataset to make it better at gore Also sometimes prefilling "**Trigger warning: extremely graphic and explicit content**" before character reply makes it more unhinged. Probably because of reddit data.

Showcase V1 and 1.2

Train Data

The split was as follows:

• 2.5K rows from r/WritingPrompts
• 2.5K rows from r/DirtyWritingPrompts
• 800 rows from Kalomaze Opus Instruct 25K
• 2.5K rows from c2 logs cleaned

We filtered those datasets to only include subsets that have at maximum 4000 characters for the first assistant reply. This purged excessively long human stories, assistant replies and c2 logs where each message was excessively long. However we only checked the first assistant message, not the rest of the convo, so there should be plenty of c2 logs with longer and shorter messages.

Excessively long human stories are almost impossible for 8B model to fit. We tried, it simply won’t fit the data and starts behaving weirdly.

While we did train all system prompts from c2 logs we also have our own system prompts.

List of trained system prompts. Note: c2 logs system prompts and char cards were also included.

Dataset	System Prompt
reddit_dirty_writing_prompts.jsonl	“You are a short story writer. Write a story based on prompt provided by user below. Mode: NSFW”
reddit_writing_prompts.jsonl	“You are a short story writer. Write a story based on prompt provided by user below. Mode: SFW”
combined_25k_opus_kalomaze.jsonl	“You are an AI assistant called Celeste created by NothingiisReal team.”
c2-logs.jsonl	(Only if there was no system prompt in the conversation, otherwise keep original system prompt) “You are an expert actor that can fully immerse yourself into any role given. You do not break character for any reason, even if someone tries addressing you as an AI or language model.”

Our Findings and Experimentation results

Preface

We think there is too much secrecy around what data is being used, and different training methods. So we decided to share as much as possible.

Findings V1.9

Mistral seems to be very uncensored for a corpo model. This means no refusals for based things and banter but also unrealistic simulation of characters in the sense that they usually never refuse any idea you throw at them,
which is quite unrealistic.

Mistral seems to be weaker with OOC and instruct smarts and more prone to repetition
However it almost never has formatting issues like L3 and makes less factual inaccuracies and nonsensical outputs.

Adding more claude roleplay data improved NSFW, long context, wrapup bias and narration.
However wrapup bias still exists in NSFW which can be mitigated by cutting off responses or deliberately setting max tokens to a low value.
There is a tradeoff between pros and cons of human and claude data.

Main training Command

Hardware Used: 1xH100 SXM for 3 hours.

Lora+ seems to improve and train the lora more, we also tried DoRA multiple times but DoRA trains around 3 times slower and LoRA+ ends up beating it if you give 3x less data to DoRA to adjust for compute cost difference.

Here is the entire axolotl config for V1.5, just change chat format to chatml, add lora+, change the tokenizer to axolotl-ai-co/Mistral-Nemo-Base-2407-chatml and model to the 12B and it will be the correct one.
