Gemini 4 Argon has reportedly appeared in the Gemini app’s model picker for at least one user, but the report is unverified and does not establish that Google has launched the model or begun a public rollout.

In a post on X, @thtbee_ says a user on a Chinese site saw the entry in the Gemini iOS app. The post also says the report could not be verified, leaving open the possibility that the screenshot is fake or that the entry does not represent a public release.

What the report says about Gemini 4 Argon

The reported sighting concerns a model-picker option labeled “4 Argon.” The post describes it as appearing alongside other Gemini model options and suggests that, if the report is genuine, a rollout could be only a few days away. That timing is speculation from the post, not a release date or schedule announced by Google.

The available material does not show whether the model-picker entry appeared for more than one user. It also does not establish whether “4 Argon” is a public model, a temporary test, an internal label, or an altered image.

What the attached model-picker screenshot shows

The supplied screenshot appears to show the Gemini app with a model picker containing “3.5 Flash-Lite,” “3.8 Flash,” “3.1 Pro,” and a checked “4 Argon” option. The “4 Argon” entry has the description “Complex tasks” beneath it. The menu also includes a “Thinking level” option.

Those labels are the visible evidence in the image, but they do not independently confirm the model’s identity, capabilities, or availability. In particular, “Complex tasks” is a menu description and should not be treated as a measured performance result.

What remains unconfirmed about availability

The supplied post and screenshot do not confirm that Gemini 4 Argon is available to the public, limited to selected users, or scheduled for release. No official Google announcement, documentation, release date, regional availability information, or independent confirmation was supplied with the report.

For now, the most supportable description is an unconfirmed Gemini app sighting. Readers should not treat the screenshot as proof that Gemini 4 Argon has launched or that a rollout is imminent.
