Questions people ask
Is Weave the same as Weights & Biases?
Weave is the LLM application tracing and evaluation part of the broader platform. W&B also covers model-training workflows. The two serve different stages of development, so choose around the problem you're investigating.
Can I use Weave for free?
Yes. I'd start with the Free plan and one representative workflow. See the pricing table for its ingestion allowance, then estimate how much your real traffic would consume before upgrading.
Does Weave work with TypeScript?
Yes, including core tracing and evaluations. Some advanced features differ from Python, so check the specific workflow you need rather than assuming full parity.
Does Weave improve AI answers automatically?
Weave gives you tools to inspect behavior and evaluate changes. You still need useful test cases, appropriate scorers, and a process for deciding which changes improve the application.
