Kuwutu-7B-CYOA-v2
Explicit Content Warning
Kuwutu-7B-CYOA-v2 is a fine-tune of
Mawdistical/Kuwutu-7B for CYOA-style interactive fiction in the adult furry, dark, and roleplay-oriented themes of the base model.
✧ Versions
✧ 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.
