Google used its I/O developer conference to unveil a wave of new AI products. The highlights: a new model called Gemini 3.5 Flash, a multimodal model called Gemini Omni, and a personal agent named Gemini Spark that runs around the clock in the cloud. The Gemini app also gets a major refresh.
According to Google CEO Sundar Pichai, Gemini 3.5 Flash beats the roughly four-month-old Gemini 3.1 Pro on nearly every benchmark. The jump is especially sharp on GDP Val, a benchmark for economically relevant tasks, Google says. In an analysis by Artificial Analysis, Flash was the only model in the upper-right quadrant of intelligence versus speed—four times faster than other frontier models, according to Pichai.
An optimized version running on Google's in-house agent platform Antigravity is even twelve times faster, the company claims. Costs come in at roughly a third to half of comparable models, according to Google. Pichai did the math: companies that shift 80 percent of their workloads to a mix of 3.5 Flash and Pro could save over a billion dollars a year. Gemini 3.5 Pro is expected next month.
Chief AI Architect Koray Kavukcuoglu stressed that the 3.5 series was built for agentic work. The model can sustain autonomous sessions for several hours and run complex coding pipelines on its own, he said. Internally, Google had it build a working operating system from scratch as a test.
