Model gemini-3.1-flash-image marked as deprecated; sources disagree on shutdown date

only one source so far

The announcement recommends switching from the model gemini-3.1-flash-image to the model gemini-nano-banana-2.1. There is conflicting information about the shutdown date: one version gives 29 October 2026, while the other says it has not been announced.

The announcement dated 6 October 2026 identifies the model gemini-3.1-flash-image as deprecated and recommends migrating to the model gemini-nano-banana-2.1. Both sources agree on these points.

However, they disagree on the shutdown date. Source 1 explicitly states that no shutdown date has been announced, while source 2 gives 29 October 2026. The supplied sources do not establish which version is correct, so this date cannot be considered definitively confirmed.

What changed

Why it matters
