AI hyperscaler CoreWeave, Inc. has [signed a definitive agreement](https://www.coreweave.com/news/coreweave-to-acquire-openpipe-leader-in-reinforcement-learning?ref=theleftshift.com) to acquire OpenPipe Inc., a leading platform for training AI agents with reinforcement learning (RL). The move strengthens CoreWeave’s technology stack, adding advanced RL and fine-tuning capabilities to its growing AI cloud ecosystem.

This follows the [recent acquisition of Core Scientific](https://www.theleftshift.com/coreweave-buys-bitcoin-giant-core-scientific-to-supercharge-ai-data-centers/), one of North America’s largest Bitcoin miners, in a $1.6 billion all-stock deal.

OpenPipe’s platform is widely adopted by developers for post-training AI agents on unique workflows, enabling them to learn from experience and improve in accuracy, performance, and reliability over time. 

> CoreWeave has acquired [@OpenPipeAI](https://twitter.com/OpenPipeAI?ref%5Fsrc=twsrc%5Etfw&ref=theleftshift.com), the RL platform behind Agent Reinforcement Trainer (ART). Devs can now train agents that learn from experience, adapt to unique workflows, and scale reliably—powered by CoreWeave’s high-performance AI cloud.

Its toolkit, Agent Reinforcement Trainer (ART), is one of the most popular open-source RL frameworks and includes tools that adapt AI models to new tasks without complex retraining.

> “Reinforcement learning is emerging as a pivotal force to strengthen model performance on agentic and reasoning tasks,” said [Brian Venturo](https://www.linkedin.com/in/brian-venturo-6719b812/?ref=theleftshift.com), 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.”

> [Kyle Corbitt](https://www.linkedin.com/in/kcorbitt/?ref=theleftshift.com), Co-founder and Chief Executive Officer of OpenPipe, added: “Our technology helps customers train highly reliable agents, bridging the gap between prototype and production. Together with CoreWeave, we can accelerate that vision and bring our technology to a wider set of enterprises.”

Earlier this year, [CoreWeave signed a five-year contract worth $11.9 billion with OpenAI](https://a42-media.ghost.io/ghost/?ref=theleftshift.com#/editor/post/68b931f55eb7ca00015b26ca) to provide its AI infrastructure to OpenAI.
