Synexian/Nexian-finetuned-llama3

Model Card for outputs

This model is a fine-tuned version of unsloth/llama-3-8b-bnb-4bit. It has been trained using TRL.

Quick start

from transformers import pipeline, AutoTokenizer

MODEL_ID = "Synexian/Nexian-finetuned-llama3"

tok = AutoTokenizer.from_pretrained(MODEL_ID, use_fast=True)
pipe = pipeline(
    "text-generation",
    model=MODEL_ID,
    tokenizer=tok,
    torch_dtype="auto",
    device_map="auto",   # will use cuda:0 if available
)

def chat(user_text, system_text="You are a helpful, concise assistant.", **gen_kwargs):
    messages = [
        {"role": "system", "content": system_text},
        {"role": "user", "content": user_text},
    ]
    try:
        prompt = tok.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
    except Exception:
        prompt = f"{system_text}\n\nUser: {user_text}\nAssistant:"
    out = pipe(
        prompt,
        max_new_tokens=256,
        do_sample=True,
        temperature=0.7,
        top_p=0.9,
        return_full_text=False,
        eos_token_id=tok.eos_token_id,
        pad_token_id=tok.eos_token_id,
        **gen_kwargs
    )[0]["generated_text"]
    return out.strip()

if __name__ == "__main__":
    print(chat("Summarize gradient descent in 5 bullet points."))
