Frontis-MA1 Paper: Training an AI4AI Model for Recursive Self-Improvement

mark_k · x · 2026-08-02

This post shares the paper details for Frontis-MA1. The paper explains that Recursive Self-Improvement (RSI) requires systems that improve the process of building AI (AI4AI), with Machine Learning Engineering (MLE) serving as an executable testbed.

The researchers introduced OpenMLE, an open full-stack system covering task environments, operator learning, and long-horizon search. The trained 35B agent utilizes execution feedback and asynchronous search to hit 71.21% on MLE-Bench Lite, beating GPT-5.5 + Codex and approaching Kimi K3. On the held-out NatureBench Lite, swapping in this model raises Match-SOTA from 50% to 70%, proving its generalization and self-evolution capabilities.
