Libraries

How to use ping98k/open-llama-7b-openthought-sft-4bit with Transformers:

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

pipe = pipeline("text-generation", model="ping98k/open-llama-7b-openthought-sft-4bit")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("ping98k/open-llama-7b-openthought-sft-4bit")
model = AutoModelForCausalLM.from_pretrained("ping98k/open-llama-7b-openthought-sft-4bit")
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]:]))

open-llama-7b-openthought-sft-4bit

Merged and 4-bit quantized OpenLLaMA 7B v2 fine-tuned on OpenThoughts-114k reasoning data with two-stage SFT.

How it was made

Base: openlm-research/open_llama_7b_v2
Stage 1 (mid): full-loss SFT on OpenThoughts-114k (3 epochs, 2K ctx)
Stage 2 (sft): assistant-only SFT on OpenThoughts-114k (3 epochs, 2K ctx)
Merged both LoRA stages into base (16bit), quantized to 4-bit NF4

Training Data

open-thoughts/OpenThoughts-114k (DeepSeek-R1 reasoning traces)
10,582 samples after filtering (<= 2024 tokens)

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("ping98k/open-llama-7b-openthought-sft-4bit", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("ping98k/open-llama-7b-openthought-sft-4bit")

messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "What is a linked list?"},
]
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True, enable_thinking=True)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
output = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tokenizer.decode(output[0], skip_special_tokens=False))
