Alphabet stock jumped 5% on Wednesday after Google debuted its latest artificial intelligence model, Gemini 3, sparking optimism from investors.
The new model is an improvement on its predecessor, Gemini 2.5, which Google released about eight months ago.
Google said Gemini 3 allows users to get better answers to more complex questions and doesn’t need as much prompting to determine the context and intent behind their requests.
Gemini 3 will be integrated into Google’s search products, the Gemini app and enterprise services.
Analysts at D.A. Davidson said in a Tuesday note that they were quickly impressed by Gemini 3, calling it a “genuinely strong model” and “the current state-of-the-art” based on preliminary testing and benchmark scores. “This latest model from Google DeepMind meaningfully moves the frontier forward,” they wrote.
With Gemini 3, Google competes against OpenAI’s GPT-5 and Anthropic’s Sonnet 4.5 models. Bank of America Securities analysts noted Gemini 3 helps close the “perceived LLM performance gap” while demonstrating healthy adoption metrics for Google’s AI surfaces.
Alphabet’s rally follows Berkshire Hathaway’s disclosure of a significant position in the company, marking one of Buffett’s firm’s largest tech investments in recent years.
