Reasoning levels

Which level to choose

Google names these settings thinking_level. Price per token is the same at every level. Higher levels usually use more output tokens. ai.google.dev (opens in a new tab)

LevelWhen to use it, per GoogleAA indexTokens/s
lowNo per-level advice published22 artificialanalysis.ai (opens in a new tab)–
medium defaultNo per-level advice published30 artificialanalysis.ai (opens in a new tab)–
highNo per-level advice published31 artificialanalysis.ai (opens in a new tab)120 artificialanalysis.ai (opens in a new tab)

Our rule of thumb: Simple or speed-critical work: low. Standard work: the lab's default. Complex work: high. Use xhigh or max only when your own tests show a gain, as OpenAI and Anthropic both advise. developers.openai.com (opens in a new tab)platform.claude.com (opens in a new tab)

Google DeepMind releases Gemini Robotics 2.5 for real-world robots

DeepMind says its new vision-language-action model, built with Gemini 4 Argon, was tested on more than 200 tasks, finishes tasks 20% to 30% faster than the previous version and packed automotive parts with a 96% success rate in proof-of-concept tests at Mercedes-Benz. It is rolling out through partners including Agile Robots, Apptronik and Boston Dynamics. The figures are DeepMind's own; more robot training and inference means more GPU demand in data centres.
