Libraries

How to use cmpatino/qwen-grpo-r4-s125 with Transformers:

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

pipe = pipeline("text-generation", model="cmpatino/qwen-grpo-r4-s125")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("cmpatino/qwen-grpo-r4-s125")
model = AutoModelForCausalLM.from_pretrained("cmpatino/qwen-grpo-r4-s125", 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]:]))

Docker Model Runner
How to use cmpatino/qwen-grpo-r4-s125 with Docker Model Runner:
```
docker model run hf.co/cmpatino/qwen-grpo-r4-s125
```

Qwen3-0.6B + GRPO on GSM8K -- intermediate checkpoint (step 125 of run r4)

inspect_evals/gsm8k, full 1319-sample test set, 10-shot, greedy: 0.7081 +/- 0.0125 (untrained Qwen/Qwen3-0.6B baseline: 0.4754 +/- 0.0138).

A statistical tie with the campaign's best model, cmpatino/qwen-grpo-r5 (0.7089 +/- 0.0125) -- see that model card for the full recipe, reward function, and caveats. Note this is the step-125 checkpoint, which scores higher than run r4's final step-129 weights (0.6907).

Runs in non-thinking mode: the chat template always emits an empty <think></think> block. Use the tokenizer shipped in this repo.
