# Google Gemini 3.1 Pro (preview) — deprecation status

> No — Gemini 3.1 Pro (preview) is not deprecated as of July 30, 2026. Google has announced neither a deprecation nor a shutdown date for it.

The current Pro-tier model, and the migration target Google names for gemini-2.5-pro and every retired 2.5 Pro preview. It has carried the "-preview" suffix since February 2026 without a stable id appearing — long enough that treating it as production is now the norm rather than the exception.
