Model Build Limits

A Model Build must be completed within 60 minutes. Here are the maximum numbers for individual parts of the build, but as you combine fields, tasks, and samples the overall limits will be lower to accomodate the maximum build time.

You can check your build time by looking at the Build Duration field in the Autopilot REST API ModelBuild Resource.

  • 50 Field Types per Assistant.
  • 1,000 Field Values per Field Type.
  • 600 Tasks per Assistant.
  • 50,000 Samples per Assistant.
  • 50 Fields per Task.

Chat limits

Please see the following page for details of these limits:

Simulator or Programmable Chat

When using the Simulator (always) or Programmable Chat (only when the Debug parameter is set to true), you are subject to the Programmable Chat channel attribute limit of 4KB. If the Autopilot Dialogue Payload is greater than 4KB then a Programmable Chat: Attributes too long will be fired and the dialogue payload will not be sent as a message attribute.
