Libraries

How to use 0xA50C1A1/Qwen3-4B-Nymphaea-RP with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="0xA50C1A1/Qwen3-4B-Nymphaea-RP")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("0xA50C1A1/Qwen3-4B-Nymphaea-RP")
model = AutoModelForCausalLM.from_pretrained("0xA50C1A1/Qwen3-4B-Nymphaea-RP", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Qwen3-4B-Nymphaea-RP

A fine-tune of Qwen3-4B-Instruct-2507 for roleplay and creative writing.

Suitable for mobile roleplay: tested on Nothing Phone 2 in Q4_K_M quantization (7-8 t/s)

The SillyTavern preset is available here. For custom presets, please use the ChatML instruct template.

Chat Example

Tested at Q8_0 quantization.

Training Notes

Trained on the latest iteration of my Darkmere dataset. This version features expanded genre variety, built upon a mix of manually curated synthetics and human-written stories.

The base weights are abliterated via Heretic prior to fine-tuning, so this fine-tune is quite uncensored.

Training Specs

Method:

Training Method: DoRA (Weight-Decomposed LoRA)
Target Modules all-linear
LoRA Rank: 32
LoRA Alpha: 32
LoRA Dropout: 0.05

Hyperparameters:

Batch Size: 2 (Per-device)
Gradient Accumulation: 2
Epochs: 2
Learning Rate: 1e-4
Optimizer: adamw_torch_fused
LR Scheduler: cosine
Noise Level: neftune_noise_alpha=5

Special Thanks

This fine-tune wouldn't be possible without the incredible work of the community:

p-e-w for developing Heretic - an essential tool for censorship removal.
SicariusSicariiStuff for developing SLOP_Detector script.
Qwen Team for their Qwen3 weights.
AMD for their Instinct™ MI300X GPU.
