CoreWeave, Inc. (NASDAQ:CRWV) is one of the fastest-growing AI stocks to invest in now. On October 8, 2025, CoreWeave announced the launch of Serverless RL, a fully managed reinforcement learning service intended to let developers train AI agents at scale without managing infrastructure. It’s the first publicly available joint offering from Weights & Biases and OpenPipe, built on CoreWeave’s AI cloud backbone.

The service scales across dozens of GPUs, requires only a Weights & Biases account / API key to use, and according to CoreWeave’s benchmarks offers ~1.4× faster training and ~40 % lower cost compared to local H100 setups.

They accomplish this by multiplexing runs across their cluster to maintain utilization and charging only for incremental tokens generated. CoreWeave says this removes the burden of provisioning VMs or bare metal, letting enterprises adopt reinforcement learning more broadly.

CoreWeave, Inc. (NASDAQ:CRWV) is a US‑based AI cloud infrastructure company headquartered in Livingston, New Jersey. It provides GPU infrastructure, developer tooling, and compute services to AI labs and enterprises. In recent months, it has been acquiring OpenPipe (RL tools) and integrating with Weights & Biases to build toward a full AI stack.

While we acknowledge the potential of CRWV to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk.
