Read more Infrastructure CoreWeave Forge Solutions Resources Log in | Sign up Contact us Contact us Clear In early September, CoreWeave, NVIDIA, and You.com ran a three-week sprint to post-train an open-weight model for agentic web search, using web-grounded search data, supervised fine-tuning (SFT), reinforcement learning (RL), and managed RL Rollouts . The final workflow reached 45.45% accuracy on BrowseComp , compared with 36.97% for the original baseline—a 22.94% relative improvement—with 31.55% fewer tool calls per task. For teams building search agents, that means more questions answered correctly with fewer tool calls. For teams running RL post-training, better training data is only part of the challenge. Inference must generate rollouts, training must update the policy, and the updated weights must reach serving replicas before the next cycle. Conventional redeployments can interrupt rollout generation and leave accelerators waiting.
