CoreWeave Forge Brings Acquired AI Tools Together in New Development Layer
Techstrong.ai, Thursday, October 1st, 2026
CoreWeave Forge combines Weights & Biases, OpenPipe and marimo with CoreWeave services in one AI development layer.
Techstrong.ai reports CoreWeave has launched Forge, uniting model training, inference, evaluation, experiment tracking and agent development in one environment built from technology it acquired over two years, including Weights & Biases Models, acquired for about $1 billion in 2025, OpenPipe reinforcement learning technology, the marimo notebook project and CoreWeave's inference, training, registry and sandbox services.
New capabilities include Agent Lens in preview, generally available ARIA and Sandboxes, and RL Rollouts for Dedicated Inference.
It comes in Free, Pro and Enterprise editions, while W&B remains cloud-agnostic.
