The Imagen 4 shutdown is now effective, not merely scheduled. Builders still calling the old model IDs need to migrate to current Gemini image generation, where model names and interaction patterns differ enough to warrant explicit compatibility testing.
OpenAI’s Assistants API is scheduled to shut down on August 26, 2026. Builders still using Assistants, Threads, Messages or Runs should move production paths to the Responses API now and test state, tool and file-search behavior before the cutoff.
