Plain Language Accessible to non-experts
Imagine a student solving math problems. They have a reference book (tools), a notebook (memory), and a teacher (feedback). Each time they try to solve a problem, the teacher tells them what's wrong, and they note this information down before trying again. This is how AxProverBase works: continuously improving until it finds the correct solution.

Imagine you're playing a puzzle game. Each time you try to solve the puzzle, the game tells you what's wrong, and you can note this information down before trying again. AxProverBase works like this, constantly trying and improving until it finds the right solution. It can also use tools to help find clues, just like using hints in a game.

Abstract
We propose a minimal agentic baseline that enables systematic comparison across different AI-based theorem prover architectures. This design implements the core features shared among state-of-the-art systems: iterative proof refinement, library search and context management. We evaluate this agentic approach using qualitatively different benchmarks and compare various frontier language models and design choices. Our results show competitive performance compared to state-of-the-art approaches, while using a significantly simpler architecture and a fraction of their cost. Additionally, we demonstrate consistent advantages of an iterative approach over multiple single-shot generations, especially in terms of sample efficiency and cost effectiveness. The implementation is released open-source as a candidate reference for future research and as an accessible prover for the community.
