Instructions to use yingfanbot/gsm-cot-llama3b-nl with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use yingfanbot/gsm-cot-llama3b-nl with Transformers:

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

pipe = pipeline("text-generation", model="yingfanbot/gsm-cot-llama3b-nl")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("yingfanbot/gsm-cot-llama3b-nl")
model = AutoModelForCausalLM.from_pretrained("yingfanbot/gsm-cot-llama3b-nl", 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]:]))

gsm-cot-llama3b-nl

Natural-language chain-of-thought SFT checkpoint, fine-tuned from meta-llama/Llama-3.2-3B-Instruct on GSM8k-Aug with natural-language reasoning steps. From the paper Bridging the Gap Between Latent and Explicit Reasoning with Looped Transformers.

This is the Stage-1 CoT initialization for the natural-language LOTUS model (yingfanbot/gsm-lotus-llama3b-nl).

It is a standard causal LM — load with from_pretrained and generate the CoT directly (no wrapper needed).
