Alphabet shares fall on report its most powerful AI model Gemini 3.5 Pro is delayed

Alphabet's Gemini 3.5 Pro AI model is delayed by months because the company wants to improve its performance, especially its ability to generate software code, which fell short of internal expectations. The delay comes as competitors like OpenAI and Meta have released newer AI models that outperform Google's current offerings at code generation, causing Alphabet's stock to drop 4%.
