The vendor sets a shutdown date; after it, API calls to the model fail and must be moved to a replacement. Deprecations can also raise prices and change behavior — price the migration before the deadline, don't scramble after it.
OpenAI's October 23, 2026 shutdown wave covers gpt-4-0613, gpt-4-turbo, o1, o3-mini, o4-mini, gpt-image-1 and ft-* models, per OpenAI's published deprecation schedule. GPT-5.6 Sol is the vendor-named replacement.
It depends on your token volume and which replacement you pick. Run the numbers in our migration cost calculator — it compares the vendor-recommended path against a cheaper alternative so you can price the move before the deadline.
