Kind: launch · Impact: medium

## In brief

- Google announced the Gemini Decisions API, powered by its Gemini Decision model, for fast, calibrated multimodal decisions.
- The API supports three question types: yes/no, choice, and rubric-scoring.
- Simon Willison describes it as almost identical to Jev's decision model API and says it reuses Jev's term "Noul".

## Why it matters

Developers who need AI-driven yes/no, multiple-choice, or rubric-based decisions now have another decision model API to evaluate alongside existing options from OpenAI and Jev.
