What does uptime mean for LangSmith Deployment usage?

Uptime is the duration your deployment’s database is live and persisting state. Uptime will be tracked as soon as your deployment is live and ends when you shut it down. Dev agent deployments are typically short-lived (used during iteration, then deleted) – whereas Production agent deployments stay live and are updated via revisions (rather than being deleted).

Does LangSmith Deployment include any free deployments?

Plus plans include 1 free small serverless deployment. If you spin up additional serverless or dedicated deployments, you’ll be charged on usage (resource time).

Why would I upgrade a base trace to an extended trace?

Base traces are short-lived (14-day retention) and ideal for quick debugging or ad-hoc analysis. They’re priced for volume and short-term utility. Extended traces are retained for 400 days. This is useful when traces include valuable feedback associated with them, such as from users, evaluators, or human labelers. This feedback makes them valuable for ongoing improvement and model tuning. LangSmith lets you choose the right retention for each trace, helping you balance cost and value.

What is the difference between a base trace and an extended trace?

Base traces have a shorter retention period of 14 days. Extended traces have a longer retention period of 400 days. You can "upgrade" base traces to extended traces for an additional fee.

What is a trace? Can it contain multiple events?

A trace represents a single execution of your application—whether it’s an agent, evaluator, or playground session. It can include many individual steps, such as LLM calls and other tracked events. Here's an example of a single trace.
