Introducing Yuclid+Newclid 3.0
In the wake of announcing Aristotle’s Gold Medal-level performance at this year’s International Math Olympiad (IMO) we’re releasing Yuclid and Newclid 3.0 - the systems responsible for our success on Problem 2, a plane geometry problem.
First open sourced in 2024, Newclid 2.0 was a user and developer-friendly improvement to AlphaGeometry. In collaboration with the creators of Newclid, we are releasing Newclid 3.0, a more powerful version of the previous solver, that can work on more problems and write clearer proofs than its prior iteration. We also made Newclid 3.0 easy to use; including Jupyter tutorial notebooks, full compatibility for prescribing problems with GeoGebra, sensible code, easy installation, and ample documentation to make examination and adaptation simple.
In addition to the improvements to Newclid, we developed a high-speed geometric solver engine we are also releasing today: Yuclid. Developed entirely in house, Yuclid is a proof generator that works with Newclid and can run up to 500X faster than AlphaGeometry 1. See for yourself.

Yuclid and Newclid require the support of an AI model that prescribes auxiliary points when their internal deductive reasoning is incapable of proving the goal. Aristotle was trained on synthetic data for this task, and we’re releasing the algorithm used to generate this data. In the coming weeks, we will also release a sample of synthetic JGEX problems with auxiliary constructions that can be used to train a similar model.
We’re excited to see how researchers and mathematicians will use Newclid 3.0 and Yuclid as we continue our quest for mathematical superintelligence!
