Google DeepMind has postponed the launch of Gemini 3.5 Pro to July 17, 2026, opting to rebuild the model from scratch rather than iterate on the existing 2.5 Pro architecture. The redesigned model targets improvements in mathematical reasoning, SVG scene generation, and image quality, and is expected to feature a 2-million-token context window along with a Deep Think reasoning layer for complex problem-solving. Google is positioning Gemini 3.5 Pro as a cost-effective alternative to premium competitors while also developing complementary models such as Gemini 4 Flash and Nano Banana Pro for image generation. The delay comes as Google faces intensifying competition from OpenAI and Anthropic in the frontier AI model race.
