Google has introduced Gemini 3, its most advanced AI model to date, delivering stronger reasoning across text, images, audio, and video.
Announced on 18th November 2025, it shipped simultaneously across Search, the Gemini app, AI Studio, Vertex AI, and developer tools, reflecting a tightly coordinated release and broad immediate availability.
Gemini 3 centres on Gemini 3 Pro with a new Deep Think reasoning mode aimed at higher‑intensity tasks.
Accuracy
Google emphasises reduced prompt‑dependence and improved accuracy, with early benchmarks and analyst reactions highlighting competitive gains versus recent frontier models.
The rollout arrives roughly eight months after Gemini 2.5, underscoring the rapid rise of Google’s AI development.
Alongside the model, Google unveiled Antigravity, an agent‑first coding environment that enables task‑level planning and execution within familiar IDE workflows.
Antigravity integrates Gemini 3 Pro and supports agentic development across end‑to‑end software tasks, with early coverage generation strong productivity features and immediate developer interest.
Nano Banana Pro
Google’s image stack also advanced with Nano Banana Pro (Gemini 3 Pro Image), reportedly improving text rendering, edit consistency, and high‑resolution output up to 4K.
The launch coincided with a notable Alphabet share price lift, signalling market confidence in Google’s AI strategy.
Google’s Gemini 3 sent Alphabet’s share price sharply higher, closing at $318.47, up 6.3% from the previous day.
The surge reflected investor enthusiasm for the model’s multimodal capabilities and enterprise integration, with analysts noting it as a decisive achievement in the AI race.
AI effect
The rally spilled over into other AI‑linked stocks: Nvidia rose 2.1% to $182.55 on strong GPU demand, while IBM gained 2.2% to $304.12 after highlighting quantum computing progress.
In contrast, Microsoft edged up only 0.4% to $474.00, as analysts flagged concerns about capital intensity in its AI investments.
Overall, the Gemini 3 announcement revived momentum across the AI market sector, with Alphabet leading the charge and peers benefiting from renewed confidence in AI’s commercial potential.
