Why it matters:
AlphaGeometry2 solves complex geometry problems better than top-tier math competitors, signaling progress in AI’s ability to mimic human-like reasoning — a hurdle for chatbots like ChatGPT.
How it works
- Hybrid brain: Marries Google’s Gemini AI (neural network) for creative “ideas” with a rules-based engine to check logical steps.
- Synthetic data: Trained on 300M+ fake theorems to bypass scarce real-world math proofs.
- Test results: Nailed 42/50 past Olympiad problems, edging past gold medalists’ average of 40.9. But stumbled on 20/29 tougher, unseen puzzles.
Reality check
- Flaws: Chokes on problems with shifting points or nonlinear equations.
- Not pure AI: Relies on hand-coded rules — not just learned intuition.
Between the lines: This isn’t just about math. Hybrid models (neural + symbolic systems) could help AI tackle engineering or physics tasks requiring precise proofs — think verifying bridge designs or drug molecules.
The catch: AI still can’t reliably ace basic logic puzzles, notes Carnegie Mellon’s Vince Conitzer: “It’s striking [these systems] solve Olympiad problems but fumble simple things. We urgently need to understand their limits as they scale.”
What’s next: DeepMind plans to expand the tech to broader math/science fields — but fully self-sufficient AI reasoning remains years away.
