On high reasoning, Gemini 3.8 Flash averages ~300 output tokens per second and a Time per Task of 2.5 minutes, just ahead of GPT-5.6 Luna (max, 2.6 minutes) and GPT-5.6 Terra (max, 3.3). Compared to Gemini 3.7 Flash, higher token usage increases Time per Task from 2.2 minutes to 2.5 minutes, and puts it behind Claude Fable 5.1 (medium, 2.1 minutes). On low reasoning, Time per Task falls to 0.8 minutes, placing Gemini 3.8 Flash on the Intelligence vs. Time per Task Pareto frontier
Google has released Gemini 3.8 Flash, its fourth Flash model in under four months - it scores 59 on the Artificial Analysis Intelligence Index and reaches the Intelligence vs. Cost per Task Pareto frontier @GoogleDeepMind released Gemini 3.8 Flash today. With high reasoning, it- Gemini 3.8 Flash (high) costs $0.58 per Intelligence Index task, the cheapest we’ve measured at this level of intelligence. This is up ~40% from Gemini 3.7 Flash despite unchanged per-token pricing, driven by a 30% increase in output tokens per task and more turns on agentic
