Google has released the Gemini Decisions API, a decision model that joins the ranks of Jev and OpenAI's decision models. Gemini supports three question types (yes/no, choice, and rubric-scoring) and is priced at 10 cents per million input tokens, with free output. It is a multi-modal model, supporting text, images, audio, video, and PDF inputs. In testing, Gemini demonstrated nuanced probability outputs for yes/no questions, providing a more detailed assessment of uncertainty compared to Jev and OpenAI. This development matters for those building or operating AI agents, as it offers an alternative decision model with specific strengths in handling various input types and providing probabilistic outputs.
