MLGym: A New Framework and Benchmark for Advancing AI Research Agents

Deepak Nathani, Lovish Madaan, Nicholas Roberts et al.

What this work does

Provides modular Gym-style research tasks, shell-execution environments, datasets and agent interfaces across a 13-task ML benchmark.

Connection to discovery

A starting interface for collecting research-agent rollouts and testing alternative policies/harnesses under controlled task definitions.

Evidence

Inspected the distinction between reproducing known performance and novel contribution, plus the executable environment architecture.

Scope and limitations

A framework enabling RL is not itself evidence of a successfully trained discovery policy. Score improvement can come from ordinary engineering within predefined task boundaries.
