# Google Gemini 1.5 Flash — deprecation status

> Yes — Gemini 1.5 Flash is retired. Google shut it down on June 17, 2026; API requests to it now fail. The recommended replacement is Gemini 2.5 Flash.

The cheap, fast half of the 1.5 generation, and the model that pushed long-context pricing down across the whole market. As with 1.5 Pro, Google has removed it from its published deprecation tables, so the shutdown date here is sourced from the community llm-model-deprecation registry.
