Instructions to use AIOR-Research/SOLID-StepORLM with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use AIOR-Research/SOLID-StepORLM with Transformers:

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

pipe = pipeline("text-generation", model="AIOR-Research/SOLID-StepORLM")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("AIOR-Research/SOLID-StepORLM")
model = AutoModelForCausalLM.from_pretrained("AIOR-Research/SOLID-StepORLM", 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]:]))

vLLM

How to use AIOR-Research/SOLID-StepORLM with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "AIOR-Research/SOLID-StepORLM"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "AIOR-Research/SOLID-StepORLM",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/AIOR-Research/SOLID-StepORLM

SGLang

How to use AIOR-Research/SOLID-StepORLM with SGLang:

Install from pip and serve model

 The model was trained with GRPO and solver-informed token-level KL supervision. It uses the COPT-style StepORLM response template.
 ## Evaluation
-Each problem was sampled 64 times. `maj@64` is majority-vote accuracy; `pass@k` uses the unbiased pass-at-k estimator. Objective correctness tolerance is `0.001`. The table uses the selected, coherent step-125 generation-B run.
