Gemini 2.5 Shutdown Dates Differ by Google Surface
This page covers which Google official surface publishes which Gemini 2.5 shutdown date. Do not average them. CLI login stays on Gemini CLI login. Notebook compute stays on Notebook limits. App Check stays on App Check enforcement. The coding-tools hub remains Gemini coding tools.
Direct answer
When does Gemini 2.5 shut down?
- Gemini API (ai.google.dev)
- Fact Gemini API deprecations, last updated 5 September 2026: gemini-2.5-pro, gemini-2.5-flash, and gemini-2.5-flash-lite show “No shutdown date announced.” gemini-2.5-flash-image shows 2 October 2026.
- Firebase AI Logic
- Fact Firebase FAQ: for 2.5 Pro / Flash / Flash-Lite, shutdown depends on the chosen Gemini API provider — Gemini Developer API 16 October 2026; Agent Platform Gemini API (formerly Vertex AI) 20 October 2026. gemini-2.5-flash-image is 2 October 2026 on both providers. Stable Gemini Live API 2.5 models are not impacted.
- Gemini Enterprise Agent Platform
- Fact Agent Platform model versions: gemini-2.5-pro, gemini-2.5-flash, and gemini-2.5-flash-lite retire 20 October 2026. gemini-2.5-flash-image retires 2 October 2026.
- One merged date
- Unknown — conflicting Official Google surfaces disagree for the same 2.5 Pro / Flash / Flash-Lite IDs. TraceCheck does not pick 16 October, 20 October, or “no date” as a universal Fact.

Keep the official surfaces separate
| Surface | 2.5 Pro / Flash / Flash-Lite | 2.5 Flash Image |
|---|---|---|
| Gemini API deprecations | Fact No shutdown date announced. | Fact 2 October 2026. |
| Firebase AI Logic · Developer API | Fact 16 October 2026. | Fact 2 October 2026, same on both Firebase providers. |
| Firebase AI Logic · Agent Platform | Fact 20 October 2026. | Fact 2 October 2026. |
| Gemini Enterprise Agent Platform lifecycle | Fact 20 October 2026. | Fact 2 October 2026. |
Official sources disagree for the same model IDs
Unknown — conflicting Gemini API deprecations still say no shutdown date for 2.5 Pro, Flash, and Flash-Lite. Firebase AI Logic and Agent Platform publish October 2026 dates for those IDs, split by provider. TraceCheck records both. It does not treat the Firebase October dates as a silent update of the Gemini API page, and it does not treat “no shutdown date announced” as proof Firebase is wrong.
Forum reports of 404s, “no longer available to new users,” or staff “not deprecated / grandfathered” replies are demand, not a third official calendar.
What this page does not do
- It does not publish a single “Gemini 2.5 dies on …” date.
- It does not own App Check’s 2 November 2026 enforcement. That is App Check.
- It does not republish Gemini CLI consumer login or Code Assist quotas.
TraceCheck maintainer: review when Gemini API deprecations, Firebase AI Logic, or Gemini Enterprise Agent Platform change 2.5 shutdown wording. Do not merge “No shutdown date announced” with Firebase October dates.
