Evaluate with Gemini decision models

Tobias Wochinger

Run decision-model evaluators on Google's gemini-decision-1 through a Google AI Studio connection.

You can now run decision-model evaluators on gemini-decision-1, the model behind Google's Gemini Decisions API. Select a Google AI Studio connection and gemini-decision-1 in the evaluator, and each Choice, Score, or Yes / no question writes a score with its probabilities and confidence. For example, you can:

• flag production answers that contradict your refund policy
• route conversations to the team that should review them
• grade answer helpfulness on a rubric from 0 to 3

Google bills only input tokens for decisions. Vertex AI connections aren't supported yet.
