CoreWeave says Forge is live, offering tools to diagnose, improve and compare AI agents. Agent Lens groups failures from recorded agent activity, while ARIA reads runs and suggests a plan. CoreWeave Sandboxes supports reinforcement learning without setting up a cluster or writing a reward by hand.

Users can compare versions on their own traces. New accounts receive a 30-day Pro trial, and the platform is free to start.
