On October 23, 2026, OpenAI deprecation schedules mark 17 model IDs for retirement. Requests to retired IDs fail with hard API errors without automatic remapping. Paste your code, config, or logs below to inspect your exposure.
Time left until the October 23, 2026 00:00 UTC shutdown threshold.

The 11 base models and snapshots listed for October 23, 2026 retirement, with recommended migration paths. Calling a bare alias (for example o4-mini) points to the same underlying version and breaks once the snapshot retires.
| Model ID that retires | Also matched as | Recommended Target |

Plus 6 fine-tuned variants: ft-gpt-3.5-turbo, ft-gpt-4, ft-gpt-4.1-nano-2025-04-14, ft-o4-mini-2025-04-16, ft-babbage-002 and ft-davinci-002. Fine-tuned models built on retiring base models require export and retraining. Legacy Completions variants of GPT-3.5 Turbo, GPT-4, and GPT-4 Turbo are scheduled on the same date.
The scanner also flags subsequent scheduled retirements so you can audit once rather than scramble repeatedly.
Retirement of older OpenAI Assistants API primitives and legacy evaluation endpoints. Anthropic's claude-sonnet-4-5-20250929 is scheduled on Anthropic platforms (cloud partners maintain independent schedules).
