Context

Users on the Development Plan may want to control their trace usage to avoid unexpected charges beyond their base trace limit. Understanding how to set and monitor trace limits is important for managing usage and costs effectively.

Answer

LangSmith allows Development Plan users to set total trace limits for their workspace to prevent exceeding desired usage thresholds.

To set your trace limit:

  1. Navigate to your workspace settings

  2. Click the "Manage usage limits" button

  3. Set your desired "Total trace limit" for the workspace

Important notes:

  • The base trace limit for Development Plan is 5,000 traces per month

  • Once you reach your set limit, you will receive tracing errors and will not be able to create new traces
