About the Gemini family
Google DeepMind's flagship family: natively multimodal with up to million-token context, in Pro (most capable), Flash (fast/cheap) and Flash-Lite (cheapest) tiers, across generations 1.0→3.6. Reasoning ('thinking') levels are configurable on modern versions.
All Gemini modelsHow this one is configured
This configuration runs in reasoning mode (thinks step-by-step before answering); version/snapshot: preview.
Also runs at: low · high effort
Effort controls how long the model thinks before answering — higher effort usually means better answers on hard problems, at the cost of speed and money. Same model underneath, so they share this page.
