Quick Start

python

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

name = "sparkle-reasoning/SparkleRL-7B-Stage1"

tok = AutoTokenizer.from_pretrained(name)
model = AutoModelForCausalLM.from_pretrained(
    name, torch_dtype=torch.float16, device_map="auto"
)

prompt = "Solve step by step: If 3x + 5 = 20, what is x?"
inp = tok(prompt, return_tensors="pt").to(model.device)
out = model.generate(**inp, max_new_tokens=256)

print(tok.decode(out[0], skip_special_tokens=True))
