Users should update their custom models to reflect these changes:

  1. Sonnet 4 users: Migrate to Haiku 4.5 (for cost efficiency) or Sonnet 4.5 (for advanced capabilities)
  2. glm-4.5 users: Migrate to glm-4.6 for enhanced features
  3. grok model users: Migrate to grok-4-fast which combines the capabilities of the retired models

Most of this shipped itself.

AskCodi maintains AskCodi, so these notes describe work we had to review too.
