What happened
Fractal, a global enterprise AI company, launched PiEvolve, an evolutionary agentic engine for autonomous machine learning and scientific discovery. PiEvolve ranks among the top agents on OpenAI's MLE-Bench, becoming the first to surpass 60% in Overall Medal Rate and 80% in MLE-Bench-Lite performance. The system continuously tests and improves solutions, integrating reasoning, code generation, and validation within a unified iterative process, delivering high-quality results efficiently for complex optimisation problems across supply chains, financial services, and data centres.
Why it matters
This launch shifts the performance ceiling for autonomous machine learning agents, offering a mechanism for continuous optimisation in enterprise AI deployments. Procurement teams and platform engineers gain access to systems that self-improve until compute limits are reached, reducing long-term operational costs and accelerating solution discovery. The demonstrated efficiency and production-readiness, including pause and resume capabilities, provide a concrete pathway for integrating advanced agentic workflows into existing ML pipelines, contrasting with earlier, less mature agentic systems.
