Libraries

How to use Sebastianpro88/Chichu-2.0-500M-Instruct with Transformers:

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

pipe = pipeline("text-generation", model="Sebastianpro88/Chichu-2.0-500M-Instruct")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Sebastianpro88/Chichu-2.0-500M-Instruct")
model = AutoModelForCausalLM.from_pretrained("Sebastianpro88/Chichu-2.0-500M-Instruct", 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]:]))

	# Chichu 2.0 500M Instruct 🐱

	A 500 million parameter language model fine-tuned from Qwen2.5-0.5B-Instruct on the
	[r0b0tlab/qwen3.8-max-glm5.2-kimi-k3-distillation](https://huggingface.co/datasets/r0b0tlab/qwen3.8-max-glm5.2-kimi-k3-distillation)
	dataset — a multi-teacher distillation corpus covering math, code, reasoning, and instructions.

	Named after Chichu the cat. 🐱

	## Model Details
	- Base model: Qwen/Qwen2.5-0.5B-Instruct
	- Parameters: 494M (2.16M LoRA adapters trained)
	- Training: LoRA fine-tuning (rank=16, alpha=32)
	- Context length: 32,768 tokens

	## Usage
	```python
	from transformers import AutoModelForCausalLM, AutoTokenizer
	import torch

	model = AutoModelForCausalLM.from_pretrained("Sebastianpro88/Chichu-2.0-500M-Instruct", torch_dtype=torch.float16, device_map="cpu")
	tokenizer = AutoTokenizer.from_pretrained("Sebastianpro88/Chichu-2.0-500M-Instruct")

	messages = [
	{"role": "system", "content": "You are Chichu 2.0, a language model named after Chichu the cat."},
	{"role": "user", "content": "What is your name?"}
	]
	text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
	inputs = tokenizer(text, return_tensors="pt")
	out = model.generate(**inputs, max_new_tokens=50)
	print(tokenizer.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
	# "My name is Chichu 2.0."
	```
