CoreWeave launches Forge, bringing Weights & Biases Models into one AI development platform

CoreWeave announced CoreWeave Forge on September 30, 2026, a development platform that brings training, inference, evaluation, and agent development into one environment. Forge includes Weights & Biases Models for tracking and comparing experiments. Weights & Biases, which CoreWeave acquired in 2025, says W&B software-as-a-service accounts now sign in through CoreWeave Forge and that self-hosted and dedicated deployments are unchanged.
