CoreWeave launches Forge to turn production traces into training data
wandb · x · 2026-10-01
CoreWeave announced Forge, a unified platform closing the loop between production observability and post-training, integrating Weights & Biases, OpenPipe post-training, and marimo notebooks.
- Problem: most teams throw away production traces daily because the tracing tool and the training tool come from different vendors and never talk to each other.
- Solution: Forge unifies wandb, OpenPipe post-training, and marimo notebooks alongside CoreWeave Training, Inference, Sandboxes, and Registry in one connected environment.
- Workflow: run, observe, curate, improve, evaluate — traces flagged in production become training datasets and eval gates.
- Works across any model, framework, or cloud; MasterClass and Canva are already building on it.
- Free, Pro, and Enterprise tiers available today.
