Gemini 3
Google released a generation built around agentic coding and understanding of different kinds of data, with a separate mode of heavier deliberation.
Why it matters
Three large laboratories arrived at the same shape: one model, adjustable deliberation, work through tools — the differences are in the detail.
By the end of 2025 frontier models had stopped differing in their premise. Each takes text, images and audio; each can think longer for a separate price; each works as an agent with tools. Gemini 3 added a Deep Think mode for the hardest problems and shipped straight into the application and into search. For the timeline this is the point of convergence: the year's remaining events are no longer about architecture but about who owns the protocol that joins it all together.
