Show HN: Optimize_anything: A Universal API for Optimizing Any Text Parameter

Optimize_anything operates in show hn launch.

Profile

We built optimize_anything, an API that optimizes any artifact representable as text — code, prompts, agent architectures, configs, even SVGs. It extends GEPA (our prompt optimizer, discussed here previously: https://arxiv.org/abs/2507.19457) far beyond prompts.The API is deliberately minimal. You provide what to optimize and how to measure it:import gepa.optimize_anything as oadef evaluate(candidate: str) -> tuple[float, dict]: result = run_my_system(candidate) return result.score, {"error": result.stderr, "runtime": f"{result.time_ms}ms"}result = oa.optimize_anything( seed_candidate="<your artifact>", evaluator=evaluate, )The evaluator returns a score plus diagnostic feedback (we call it "

The company sits in the show hn launch segment, where it competes on its core product or service.

Its current recorded stage is Show HN launch.
