Understanding Prompt Versions

TrueFoundry automatically tracks every change you make to a prompt template, enabling experimentation, history, and collaboration. Each time you modify a prompt, a new version is created with a unique version number, allowing you to:
  • Track changes and version history
  • Use any version and reverting applications to a previous version of prompt
  • Collaborate with team members on prompt development

​
Prompt Registry

The Prompt Registry is your central hub for managing all saved prompts. Access all your prompts through the Prompt Registry if you have read or write permissions.

The registry displays:
  • Name: The prompt identifier
  • Latest Version: Current version number
  • Model Name: Associated model (if configured)
  • Description: Brief description of the prompt’s purpose
  • Repository: The workspace/repository location
  • Created By: Author information and creation time

​
Viewing Prompt Versions

Click any prompt in the registry to see detailed version history and configuration.

You can also load any version directly into the Playground for testing and experimentation. Click the “Try in Playground” button to:
  • Load the selected prompt version into the Playground
  • Test the prompt with different inputs
  • Make modifications and create new versions
  • Generate code snippets for implementation

​
Compare Versions (Diff Mode)

Use the Version Difference tab to see exactly what changed between versions in standard github like diff view.
