Instructions to use kfdong/STP_model_Lean with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use kfdong/STP_model_Lean with Transformers:

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

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

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("kfdong/STP_model_Lean")
model = AutoModelForCausalLM.from_pretrained("kfdong/STP_model_Lean")
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 kfdong/STP_model_Lean with vLLM:

Install from pip and serve model

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

Use Docker

docker model run hf.co/kfdong/STP_model_Lean

SGLang

How to use kfdong/STP_model_Lean with SGLang:

Install from pip and serve model

# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "kfdong/STP_model_Lean" \
    --host 0.0.0.0 \

1. Evaluation Results

The table below compares the pass@3200 performance of STP (our model) and DeepSeek-Prover-V1.5 on miniF2F-test and ProofNet-test.

	miniF2F-test	ProofNet-test
DeepSeek-Prover-V1.5-SFT	53.3% ± 0.5%	21.0% ± 0.9%
DeepSeek-Prover-V1.5-RL	54.9% ± 0.7%	22.0% ± 0.5%
STP	61.7% ± 0.6%	23.1% ± 0.5%

2. Dataset

We also release the dataset here, which contains:

Extracted examples from mathlib4,
Generated correct proofs of statements in LeanWorkbook,
Generated correct proofs of conjectures proposed by our model during self-play training.

Our final model is finetuned from DeepSeek-Prover-V1.5-SFT with this dataset for 1 epoch.
