- Use the model name directly, e.g. "gemini-2.0-flash", "gemini-1.5-pro", or "gemini-2.5-pro-preview-05-06".
- The examples expect GOOGLE_API_KEY; rename it only if your application config maps the new variable.

About Gemini Decision 1
Gemini Decision 1 is Google's first decision model, released November 11, 2026 with the Decisions API in the Gemini API and Google AI Studio. It does not generate text: given one input of text, images, audio, video or PDF and up to 1,000 typed questions per request, it returns calibrated probabilities for yes/no, choice and score (rubric) answers, with zero output tokens. Google aims it at bounded choices such as tool selection, policy checks, model routing and context grading. The input limit is 262,144 tokens.
