# AlphaEvolve helps lower the matrix multiplication exponent ω to below 2.371177

A paper by Alman, Vassilevska Williams and co-authors including DeepMind researchers (arXiv 2608.16884) improved the bound on the matrix multiplication exponent from ω < 2.371339 to ω < 2.371177. AlphaEvolve refined the optimiser used in the laser-method analysis.

## Key facts
- ω < 2.371177 (previous: 2.371339)
- Humans reformulated the optimisation problem; AlphaEvolve improved the numerical optimisation

## What happened

Leading researchers on fast matrix multiplication used AlphaEvolve inside their laser-method pipeline to squeeze out a new record bound.

## Why it matters

Progress on ω comes in tiny, hard-won steps. AI now contributes to the asymptotic theory as well as to small concrete algorithms.
