OpenAI Deprecations Put Prompts, Evals, and Images on a Clock
OpenAI's deprecations page now gives developers several concrete migration deadlines. Reusable prompts and the Evals platform were announced for deprecation on June 3, 2026, while older GPT Image models were notified on June 2, 2026.
Technical Signals
- Prompt Objects: v1/prompts and reusable prompt objects are scheduled to shut down on November 30, 2026.
- Evals Platform: Existing evals become read-only on October 31, 2026, with dashboard and API shutdown on November 30, 2026.
- Image Models: Older GPT Image models are scheduled for removal on December 1, 2026.
- Migration Rule: Move reusable prompt content into application code and plan image workloads around gpt-image-2.
What Changed
OpenAI's deprecation schedule turns several convenience layers into migration work. Reusable prompts, the Evals platform, and older image models now have explicit late-2026 deadlines, which means teams should inventory dependencies before the dates become release blockers.
Architecture Impact
Prompt objects are easy to adopt and hard to govern at scale. Moving prompt content into application code improves version control, review, and reproducibility. Evals migrations need the same discipline: preserve datasets, graders, baseline results, and ownership before dashboards become read-only.
Migration Plan
Search for API calls to v1/prompts, dashboard-managed prompt references, eval IDs, and older image model names. Move prompts into code or configuration, recreate evaluations in the recommended workflow, and update image generation to the supported model path.
Risk Management
Deprecations are operational risk, not only developer chores. Add CI checks for removed model names, publish internal migration dates ahead of vendor deadlines, and keep a rollback plan for workloads that depend on image quality or evaluation comparability.
