Google launches Gemini 3 Pro and Antigravity, an agent-first coding platform
Gemini 3 Pro ships with a new reasoning engine, and on the same day Google introduced Antigravity, a coding platform built around agents.
Google has announced Gemini 3 Pro, a new model generation that comes with a new reasoning engine. On the same day, the company introduced Antigravity, a coding platform designed agent-first.
The new reasoning engine is the processing part inside the model; it decides how a request is analysed and which step comes next before a result is returned. With Antigravity, the change sits at the tool layer: instead of writing every line themselves, users give an agent a task and it carries out the steps inside the coding environment.
For businesses, this approach has a direct effect on how development teams are organised. If an agent can take on repetitive steps such as reading source code, producing changes and running tests, engineering teams can concentrate on design and decision-making.
What to keep in mind is that agent-style coding platforms raise new governance requirements: who assigns the work, which parts of the source code the agent may touch, and how results are approved. The announcement gave no performance figures, pricing or access conditions.
