# Kuwutu-7B-CYOA-v2

### Explicit Content Warning

Kuwutu-7B-CYOA-v2 is a fine-tune of [Mawdistical/Kuwutu-7B](https://huggingface.co/Mawdistical/Kuwutu-7B?not-for-all-audiences=true) for CYOA-style interactive fiction in the adult furry, dark, and roleplay-oriented themes of the base model.

## ✧ What Changed in v2

v2 is a retrained release with substantially better results than v1 on the private generation benchmark and automated loop detection.

## ✧ Intended Use

This model is intended for long-form interactive fiction, especially CYOA-style scene continuation and branching narrative in the themes of Kuwutu-7B.

It uses the ChatML template. Prompts can provide the current scene, player state, relevant context, and instructions for the next continuation.

## ✧ Training Details

| Setting | Value |
|---|---|
| Base model | `Mawdistical/Kuwutu-7B` |
| Method | LoRA SFT, merged for this repository |
| Release checkpoint | `run0072`, checkpoint `282` |
| Rank / alpha | `16 / 16` |
| LoRA+ ratio | `4.6` |
| Optimizer | Muon with AdamW fallback parameters |
| Learning rate | `2.2e-4` |
| Weight decay | `10` |
| Epochs | `2` |
| Context cutoff | `15,872` tokens |
| Precision | BF16 |
| Chat template | ChatML |

The training data consists of permissioned adult CYOA / interactive-fiction writing and a small amount of related long-form writing. The dataset is not redistributed with the model.

## ✧ Evaluation

Results from a private pairwise LLM-judged benchmark of generated continuations:

| Candidate | Elo-like score | Catastrophic-loop rate |
| :--- | ---: | ---: |
| Real | 510.9 ± 46.9 | 0/114 (0.0%) |
| Kuwutu-7B-CYOA-v2 | 72.7 ± 37.3 | 0/112 (0.0%) |
| Kuwutu-7B | 4.0 ± 31.8 | 0/114 (0.0%) |
| Kuwutu-7B-CYOA-v1 | -46.6 ± 34.1 | 16/112 (14.3%) |
| Dummy | -423.1 ± 45.6 | 0/114 (0.0%) |

These private internal results should be treated as directional rather than as broad capability benchmarks.

## ✧ Limitations

The model may hallucinate story facts, drift from scene context, repeat phrases, overproduce prose, or mishandle choice structure. Its behavior remains strongly influenced by Kuwutu-7B and the narrow interactive-fiction training distribution.
