arXiv:2602.02660v3 Announce Type: replace Abstract: A critical bottleneck in automating AI research is the execution of complex machine learning engineering (MLE) tasks. MLE differs from general software engineering due to computationally expensive evaluation (e.g., model training) and opaque performance attribution. Current LLM-based agents struggle here, often generating monolithic scripts that ignore execution costs and causal factors. We introduce MARS (Modular Agent with Reflective Search), a framework optimized for autonomous AI research. MARS relies on three pillars: (1) Budget-Aware Pl
The proliferation of LLM-based agents has highlighted critical bottlenecks in automating complex AI research tasks, particularly in computationally expensive evaluations and opaque performance attribution.
This development addresses a fundamental limitation in current AI agent capabilities, potentially accelerating the pace of AI research itself and collapsing white-collar workflows in scientific discovery.
AI agents are evolving from generalized task executors to specialized frameworks capable of nuanced, budget-aware, and reflective search for scientific and engineering problems.
