How does Weights & Biases pricing work?
The value metric is a blend of seats and three meters. Model seats ('Train and fine-tune AI models') run 'Up to 5' on Free and 'Up to 10' on Pro, Weave seats ('Develop GenAI applications') are included on every plan, and both are Customizable on Enterprise. Storage is '5 GB/mo' on Free and '100 GB/mo' on Pro with 'Additional storage $0.03/GB', and Weave data ingestion is '1 GB/mo' and '1.5 GB/mo' with 'Additional data ingestion $0.10/MB'. Inference and CoreWeave Sandboxes carry credits 'for a limited time', $5 a month on Pro for inference and $10 and $25 a month for sandboxes. Seats price the collaboration, and ingestion prices the trace volume that GenAI observability generates.
The motion is a self-serve ladder with a sales-led top. 'Pricing that works for everyone' and 'The best tools for AI developers' sit over the hosting toggle and three cards: Free at '$0/mo' with GET STARTED, Pro with 'START YOUR 30 DAY FREE TRIAL', and Enterprise 'Custom plans' with CONTACT US. Pro is 'For early-stage teams fewer than 50 employees', and customers beyond that move to Enterprise, which makes company size the trigger for the sales conversation. An academic band, 'Free forever for academic research', sits under the cards, and a Compare plans matrix repeats the three CTAs in its header before the FAQ.
The FAQ lays out the billing mechanics. 'The Pro plan is billed monthly or annually upfront', Model seats prorate when added mid-term, and 'Weave data ingestion, W&B Inference, and storage are billed monthly in arrears based on your usage', while 'Enterprise plans are invoiced annually upfront'. That is a platform fee in advance and usage in arrears, a clean hybrid bill. The ingestion row adds 'Volume discounts available with annual commitments', which shows where the commercial room sits: trace volume is the meter that grows with a GenAI app in production, and commitments are how large users buy it. A headcount gate that routes growing companies to Enterprise is the idea worth borrowing.
