Short answer

Paid plans start at $60/mo. There's also a free plan.

Weights & Biases has a free tier, while Pro starts at $60 per month, billed monthly upfront. Free includes up to 5 model seats, 5 GB of storage per month and 1 GB of monthly data ingestion; Pro raises those limits to 10 seats, 100 GB and 1.5 GB. Enterprise pricing is custom, and Academic (Pro license) is free for research unrelated to for-profit entities. The pricing information lists a 30-day free trial but doesn't specify its scope.

04Is Weights & Biases worth the money?

Weights & Biases has strong coverage across ML work: experiment tracking, data and model management, collaboration, and generative-AI evaluation. The free tier is useful for small projects, but its 5 GB storage and 1 GB ingestion caps are modest. Pro gives more room for a fixed starting price, though extra ingestion and storage add usage charges. Enterprise pricing and annual upfront invoicing make contract terms worth checking before you commit.

Weights & Biases pricing FAQ

Are Weights & Biases free?

Yes. The Free plan costs $0 per month and includes up to 5 model seats, 5 GB storage per month and 1 GB data ingestion per month. Academic (Pro license) is also listed at $0 for research unrelated to for-profit entities. A 30-day trial is listed, but its scope isn't specified.

How much does AI training typically cost?

The published pricing details don't publish a typical compute bill or total AI training cost. They list W&B platform charges instead: Pro starts at $60/month, additional storage costs $0.03/GB, and additional Pro ingestion costs $0.10/MB. Your total depends on usage beyond the plan allowances.

What are Weights & Biases by CoreWeave?

Weights & Biases is described as an AI developer platform for building, evaluating, fine-tuning and monitoring ML models. The published product information doesn't establish what “by CoreWeave” means or specify a relationship with CoreWeave, so we can't confirm that wording.

Which AI tool is best for pricing?

There isn't one best tool for every pricing job. The published description positions Weights & Biases for ML and generative-AI workflows, including experiment tracking, model management and application evaluation. It doesn't describe a pricing-comparison tool. For W&B, compare your seat, storage and ingestion needs with its plan caps and usage rates.
