Reusable prompts (v1/prompts API) shut down
23 days left — Nov 30, 2026
- What stops working
- The v1/prompts API and stored reusable prompt objects stop working.
- Who is affected
- Any integration that references prompt IDs instead of holding prompt text in code — including teams that followed the Assistants migration guide, which mapped Assistants to Prompts.
- Official migration path
- Move prompt content, model and tool configuration into application code.
- What the official path does not cover
- Teams that migrated off Assistants in August 2026 by moving to Prompts face a second migration 96 days later.
