Gemini 3.5 launches with Flash, Omni, and Antigravity 2.0 agent stack
Google announced Gemini 3.5 Flash alongside Gemini Omni (multimodal generation including video) and Antigravity 2.0. Per Google, Flash benchmarks at 76.2% on Terminal-Bench 2.1, 1656 Elo on GDPval-AA, 83.6% on MCP Atlas, and 84.2% on CharXiv Reasoning, sitting in the top-right quadrant of Artificial Analysis's Intelligence Index. Google reports roughly 4x faster output tokens/sec than other frontier models at under half the cost.
Flash is the new default for agentic loops where latency dominates cost — Google's 4x throughput claim plus the sub-half-cost framing changes the cost-per-task math more than the headline benchmark scores. If you're still routing everything through Pro tier, rerun the numbers this week.
