04Is Weights & Biases worth the money?
The Free plan is a sensible starting point for a small project that fits within its seat, storage and ingestion allowances. Pro is worth pricing when a team needs up to 10 model seats, team access controls, service accounts or CI/CD automations; its $60 starting price is only part of the budget if usage exceeds included storage or Weave ingestion. Enterprise is a custom quote for security and compliance needs. Ask W&B to estimate ingestion, inference and seat costs using your expected workload before committing.
