Instructions to use OrionLLM/GRM-7b with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use OrionLLM/GRM-7b with Transformers:

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

pipe = pipeline("text-generation", model="OrionLLM/GRM-7b")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("OrionLLM/GRM-7b")
model = AutoModelForCausalLM.from_pretrained("OrionLLM/GRM-7b")
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 OrionLLM/GRM-7b with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "OrionLLM/GRM-7b"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "OrionLLM/GRM-7b",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/OrionLLM/GRM-7b

SGLang

How to use OrionLLM/GRM-7b with SGLang:

Install from pip and serve model

logo

GRM-7b is a general-purpose reasoning-focused 7B model fine-tuned to improve multi-domain reasoning (math, logic, coding, and broad problem-solving). It is designed to be a strong, practical “daily driver” for general reasoning tasks and as a solid base for further fine-tuning.

Key features

Dedicated reasoning behavior for general tasks (stepwise problem solving, better consistency).
Strong 7B-scale model — practical for local inference and experimentation.
Multi-domain mixture: reasoning + code + math + (some) medical reasoning data.
Fine-tune friendly: intended as a good starting point for your own SFT/GRPO/DPO pipelines.
