Google I/O Previews Gemini Spark and Antigravity
Google I/O 2026 featured announcements for Gemini Spark and Antigravity; neither product has shipped yet.
At Google I/O 2026, Google announced two new products: Gemini Spark and Antigravity. Both were previewed as forthcoming rather than immediately available. Developer and writer Simon Willison published notes on both, while observing that he prefers to write about products that have actually shipped rather than pre-release announcements—a framing that itself signals caution about reading too much into the reveals.
The distinction matters for practitioners: Google I/O has a history of ambitious previews that take months to reach general availability, and the gap between announcement and usable product can be significant. For teams evaluating AI tooling, the names Gemini Spark and Antigravity mark new directions Google is signaling, but the practical timeline—access, pricing, API availability—remains unconfirmed until the products formally launch. Willison's notes offer an early read for those tracking Google's roadmap without overstating what is actually in hand.
