Google previously rolled out Gemini to Google TV Streamer, and this update suggests ongoing support for older hardware rather than phasing them out.

So far, Gemini is confirmed on the 4K Chromecast with Google TV, while there have been no widespread reports of Gemini appearing on the HD-only Chromecast model yet.

This upgrade comes amid ongoing concerns about the Chromecast lineup’s longevity and patching for older units, making the AI feature a notable enhancement for current 4K users.

Google is expanding Gemini AI features to the original 4K Chromecast with Google TV, not limited to the newer Google TV Streamer, with reports confirming Gemini on the 4K Chromecast running firmware UTTC.250917.004 and the October 2025 security patch.

The rollout appears to be server-side and may have begun quietly, with sightings emerging over several days after a period of silence.

users should keep their devices updated with the latest firmware and security patches to improve chances of receiving Gemini as the rollout expands.

The rollout aligns with devices showing Gemini features after updating to firmware UTTC.250917.004 (October 2025 patch level), indicating a server-driven push.

Users with a 4K Chromecast should check their device settings to see if Gemini AI features are available and enable a conversational AI experience.

The development offers reassurance to Chromecast users by delivering modern AI-powered features to existing devices, signaling continued support rather than a shift away from older hardware.
