Instructions to use beyoru/Luna-Fusion-RP with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use beyoru/Luna-Fusion-RP with Transformers:

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

pipe = pipeline("text-generation", model="beyoru/Luna-Fusion-RP")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("beyoru/Luna-Fusion-RP")
model = AutoModelForCausalLM.from_pretrained("beyoru/Luna-Fusion-RP")
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]:]))

🌙 Luna-Fusion-RP – Roleplay Chat Model series

Luna is a conversational AI model designed for immersive roleplay (RP) and natural chatting.
It is fine-tuned to respond in a more engaging, character-driven style compared to standard instruction-tuned models.

This is a merging version of all RP models, base model in evolution merged method with the CREATIVE WRITING dataset.

This influence by the success when merging model to impoveing performance in my test.

Notes:

Optimized for roleplay-style conversations
Flexible: can be used for creative writing, storytelling, or character interactions
For best performance, you should describe the system prompt for your character.
3 models is merging.
