CoreWeave acquires agent-training startup OpenPipe (techcrunch.com)

CoreWeave has announced its acquisition of OpenPipe, a Y Combinator-backed startup specializing in reinforcement learning tools designed to help enterprises build customized AI agents. This move strengthens CoreWeave’s AI cloud services by integrating OpenPipe’s popular open-source toolkit, ART (Agent Reinforcement Trainer), which enables scalable training of intelligent systems through reinforcement learning—a technique that rewards AI models for correct task completion and enhances their performance on agentic and reasoning tasks. The acquisition is significant as it positions CoreWeave to better serve both large AI labs and smaller enterprises by providing the substantial computational resources needed for tailored AI agent training. Following its recent purchase of AI developer platform Weights & Biases, CoreWeave is clearly expanding its AI ecosystem vertically and horizontally, creating a more comprehensive platform for developing, training, and deploying reinforcement learning-powered AI models. With OpenPipe’s team joining CoreWeave and its customers transitioning to CoreWeave’s platform, this deal highlights the increasing demand for enterprise-specific AI solutions that require highly specialized and resource-intensive training workflows.
