Fractal launches PiEvolve, an agentic AI engine for autonomous machine learning, ranking among the top systems on OpenAI’s MLE-Bench.
Fractal on Tuesday introduced PiEvolve, an evolutionary agentic engine designed to automate machine learning and scientific discovery, marking a new step in the race to build self-improving enterprise AI systems.
The company said PiEvolve ranks among the top-performing agents on OpenAI’s MLE-Bench, a benchmark used to evaluate how effectively AI systems solve real-world machine learning challenges. According to Fractal, PiEvolve is the first evaluated agent to surpass a 60 percent Overall Medal Rate and 80 percent performance on MLE-Bench-Lite — thresholds widely regarded as significant in autonomous machine learning research.
Unlike traditional models that are trained and then deployed, PiEvolve continuously refines its own solutions until available computing resources are exhausted. Built on a graph-structured search architecture, the system integrates reasoning, code generation and validation into a single iterative loop, enabling it to address complex optimization problems across supply chains, financial services and data center operations.
Fractal said the system delivers competitive performance within a 24-hour run and can identify high-quality solutions even within 12 hours, highlighting efficiency alongside capability.
“MLE-Bench is widely regarded as a gold standard for evaluating AI agents,” said Srikanth Velamakanni, co-founder and group chief executive of Fractal. He described the results as validation of the company’s broader ambition to deploy continuously improving AI systems within enterprises.

Key features of PiEvolve include continuous optimization, priority-based memory sampling to avoid local optima, dual-path debugging and enhancement strategies, and production-ready controls such as pause-and-resume functionality for long-running workloads.
Suraj Amonkar, chief AI research and platforms officer at Fractal, said the system reflects the company’s focus on building autonomous agents capable of sustained reasoning and evolutionary learning.
Fractal, listed on India’s National Stock Exchange under FRACTAL, serves Fortune 500 organizations globally and operates research initiatives focused on foundational and agentic AI systems.
