# qwen-4b-2507-rp-mahou
|
||
|
||
A full-parameter SFT of [`Qwen/Qwen3-4B-Instruct-2507`](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507) on [`flammenai/flame-kindling-v1`](https://huggingface.co/datasets/flammenai/flame-kindling-v1) for creative roleplay and character interaction.
|
||
|
||
## Highlights
|
||
|
||
- Base: Qwen3-4B-Instruct-2507
|
||
- Method: full-sequence SFT (no LoRA)
|
||
- Dataset: flame-kindling-v1 (RP / creative writing)
|
||
- Precision: bf16
|
||
- Chat template: Qwen3 (use `enable_thinking=False` for RP)
|
||
|
||
## Usage
|
||
|
||
```python
|
||
import torch
|
||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||
|
||
MODEL_ID = "Pranavz/qwen-4b-2507-rp-mahou"
|
||
|
||
tokenizer = AutoTokenizer.from_pretrained(MODEL_ID)
|
||
model = AutoModelForCausalLM.from_pretrained(
|
||
MODEL_ID,
|
||
torch_dtype=torch.bfloat16,
|
||
device_map="auto",
|
||
)
|
||
|
||
messages = [
|
||
{"role": "system", "content": "You are a creative roleplay assistant. Stay in character, write vividly, and use asterisks for actions."},
|
||
{"role": "user", "content": "*walks into the tavern, shaking off the rain* Evening, barkeep. Got a room?"},
|
||
]
|
||
|
||
text = tokenizer.apply_chat_template(
|
||
messages,
|
||
tokenize=False,
|
||
add_generation_prompt=True,
|
||
enable_thinking=False,
|
||
)
|
||
inputs = tokenizer(text, return_tensors="pt").to(model.device)
|
||
|
||
with torch.inference_mode():
|
||
out = model.generate(
|
||
**inputs,
|
||
max_new_tokens=512,
|
||
temperature=0.8,
|
||
top_p=0.9,
|
||
top_k=40,
|
||
repetition_penalty=1.1,
|
||
do_sample=True,
|
||
)
|
||
|
||
print(tokenizer.decode(out[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
|
||
```
|
||
|
||
## Recommended sampler settings
|
||
|
||
| Parameter | Value | Notes |
|
||
|---|---|---|
|
||
| `temperature` | 0.7 – 0.85 | creative without going off-rails |
|
||
| `top_p` | 0.9 | trim the long tail |
|
||
| `top_k` | 40 | hard vocab cap |
|
||
| `min_p` | 0.05 | optional, often nicer than top_p alone |
|
||
| `repetition_penalty` | 1.05 – 1.15 | RP models love loops — kill them |
|
||
| `max_new_tokens` | 512 – 1024 | RP needs room |
|
||
|
||
Always pass `enable_thinking=False` to the chat template — RP doesn't want CoT.
|
||
|
||
|
||
## Limitations
|
||
|
||
- Trained on a single curated RP dataset; expect a particular tone (vivid, action-asterisk style)
|
||
- Not safety-tuned beyond what the base model provides
|
||
- English only
