intermediate Published 23 May 2026
Action Steps
  1. Test model upgrades on a staging environment before deploying to production
  2. Configure automated testing for prompt regressions across different AI models
  3. Run comparison tests between old and new model versions
  4. Apply regression testing to catch silent breaks in extraction prompts
  5. Analyze test results to identify and fix regressions before deployment
