Canva and MasterClass are already using the tool across models and clouds.
CoreWeave announced CoreWeave Forge on September 30, 2026, at its Fully Connected conference in San Francisco. The development platform connects the full artificial intelligence lifecycle, including running, observing, curating, improving, and evaluating models and agents. MasterClass and Canva are already building on the service, which works across external models, frameworks, and cloud providers.
The platform integrates tools such as Weights & Biases Models, post-training technology from OpenPipe, and the open-source marimo notebook project. New features include CoreWeave ARIA, an automated coding agent, and CoreWeave Sandboxes, both now generally available. It also features CoreWeave Agent Lens, an observability tool that detects 20% more critical failures and resolves issues at one-tenth the cost compared to a general-purpose frontier model benchmark.
CoreWeave Forge also includes post-training services with serverless reinforcement learning, which trains 1.4 times faster at 40% lower cost than self-managed systems. CoreWeave Inference adds preview access to RL Rollouts, which hot-loads checkpoints into live deployments without redeploying. The platform is offered in Free, Pro, and Enterprise tiers, with a 30-day trial for the Pro tier.
