Our verdict

CoreWeave folded Weights & Biases into a single model-and-agent development layer: track experiments, fine-tune with serverless RL/SFT, and serve open-weight models without leaving the platform. Trusted by builders at Canva, Cohere, and Perplexity. Best for teams already living in W&B or doing serious post-training; hobbyists may find the usage-based bill harder to predict.

Cons

Usage-based pricing across many dimensions can get expensive fast
Brand-new platform (launched Sept 2026) — ecosystem and docs still maturing
Workflow lock-in risk: checkpoints are portable, but the integrated toolchain is CoreWeave's
