What is Weco?
Weco is a platform for self-improving code. It automates code optimization by iteratively refining your code against any metric you define - whether that's speed, accuracy, latency, or cost. Powered by our AIDE algorithm, Weco systematically explores code variants, tests them, and delivers better-performing solutions.
Here's what Weco can do (keep your eye on the Best Solution panel):
