- The rumor previously reported in some overseas media about the discontinuation of the custom AI expert feature “Gem (Gems)” appears to be true, not just a rumor.
- App file analysis of the Android version of the “Google” app (v17.51.18 update) confirmed that resource codes regarding the notice of “Gem (Gems)” discontinuation have been added.
- Development toward the discontinuation of “Gem” is currently underway, and it is expected that the discontinuation notice for “Gem” will start displaying once the discontinuation date is finalized.
There was a rumor regarding the discontinuation of “Gem (Gems)”, the custom AI expert feature in the Google AI “Gemini” app, which was previously reported by some overseas sources.
However, it turns out that the rumor was not just a rumor, but the truth. We bring you the details in our original app file analysis report content “App Analysis” here on Jetstream.

As a result of analyzing the app files of the Android version of the “Google” app version v17.51.18 released on Thursday, August 20, 2026, we confirmed that resource codes related to the notice of “Gem (Gems)” discontinuation have been added. After “Gem” is discontinued, to continue using features similar to “Gem,” users will apparently have no choice but to save their Gem prompts for secondary use or reuse them as custom instructions for “Skills.”

In other words, development toward the discontinuation of “Gem” is currently underway, and it is expected that the discontinuation notice will start appearing once the end date is decided.
