What is AlphaEvolve?

AlphaEvolve

AlphaEvolve is an evolutionary coding agent that combines the creative code generation of LLMs with automated program evaluators in a closed-loop system. It iteratively evolves code to discover faster algorithms and solutions to open problems, optimizing programs rather than model weights. AlphaEvolve is widely recognized for achieving a new state-of-the-art in matrix multiplication -- improving on Strassen’s 56-year record -- by having an LLM ensemble propose code improvements which are filtered by performance test. The agentic paradigm of using LLMs plus evolutionary search instead of reinforcement learning proved effective for algorithmic discovery, yielding a 23% kernel speedup in model training and other infrastructure gains (DeepMind paper).
