**AI-MO/Kimina-Prover-Distill-1.7B** is a theorem proving model developed by Project Numina and Kimi teams, focusing on competition style problem solving capabilities in Lean 4. It is a distillation of **Kimina-Prover-72B**, a model trained via large scale reinforcement learning. It achieves 72.95% accuracy with Pass@32 on MiniF2F-test.

# Quick Start with vLLM

You can easily do inference using vLLM:

```python
from vllm import LLM, SamplingParams
from transformers import AutoTokenizer
model_name = "AI-MO/Kimina-Prover-Distill-1.7B"
model = LLM(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
problem = "The volume of a cone is given by the formula $V = \frac{1}{3}Bh$, where $B$ is the area of the base and $h$ is the height. The area of the base of a cone is 30 square units, and its height is 6.5 units. What is the number of cubic units in its volume?"
formal_statement = """import Mathlib
import Aesop
