LIVINGSTON, N.J. & BELLEVUE, Washington – September 3, 2025 – CoreWeave,
Inc. (NASDAQ: CRWV), the AI Hyperscaler™, today announced a definitive agreement
to acquire OpenPipe Inc, a leading platform for training AI agents with reinforcement
learning (RL).
OpenPipe has created advanced machine learning techniques that have become a
preferred developer framework to train agents. Its technology democratizes RL for
developers at AI labs to post-train on a builder’s own unique workflows. Agents are then
able to learn from experience, increasing in accuracy, performance, and reliability over
time.
“Reinforcement learning is emerging as a pivotal force to strengthen model performance
on agentic and reasoning tasks,” said Brian Venturo, Co-founder and Chief Strategy
Officer, CoreWeave. “By combining OpenPipe’s advanced self-learning tools with
CoreWeave’s high-performance AI cloud, we’re expanding our platform to give
developers at AI labs and beyond an important advantage in building scalable intelligent
systems.”
AI labs are investing heavily in reinforcement learning to solve problems autonomously
and deliver better outcomes for users. OpenPipe has built one of the most widely used
open-source RL toolkits for training agents, Agent Reinforcement Trainer (ART), as well
as a best-in-class tool for automatically adapting AI models to novel tasks making it
easy for enterprises to gain custom models without the complexities of training.
“Our technology helps customers train highly reliable agents, bridging the gap between
prototype and production,” said Kyle Corbitt, Co-founder and Chief Executive Officer,
OpenPipe. “Together with CoreWeave, we can accelerate that vision and bring our
technology to a wider set of enterprises that are eager to build more reliable, higher-
performing, and cost-effective AI systems.”
CoreWeave is the leading AI cloud platform, purpose-built for the scale, performance,
and expertise needed to power AI innovation. Building on the recent acquisition of
Weights & Biases, the addition of OpenPipe further advances CoreWeave’s strategy to
deepen vertical integration across its technology stack. With new reinforcement learning
and fine-tuning capabilities, CoreWeave is giving customers greater flexibility to train,
adapt, and optimize their AI models.
Terms of the acquisition are not being disclosed.
