Google Launches Gemini Decisions API for Fast Bounded Judgments

Google has launched its Gemini Decisions API, providing developers with a dedicated endpoint for receiving bounded judgments from an artificial intelligence model without generating written answers. Powered by Gemini Decision 1 and available in Google AI Studio, the service processes up to 1,000 independent questions within a single request. Rather than returning a traditional chatbot response, the endpoint supplies fixed choices, probabilities, and confidence scores that application code can utilize directly for routing requests or checking policies.

The system supports yes/no inquiries, selections from user-supplied lists, and evaluations against predefined rating scales across combined text, image, audio, video, and PDF inputs. The total context window reaches 262,144 tokens, while Google reports end-to-end latency of 150 to 250 milliseconds for contexts under 16,000 tokens. The service is priced at $0.10 per million input tokens with no additional output-token charges. Google notes that Gemini Notebook and Search already utilize the infrastructure to streamline model tier selection and bolster security layers.

Google's new API delivers rapid AI probability judgments at ten cents per million input tokens.

Managing API Limitations

While the endpoint increases processing efficiency, documentation highlights specific failure cases that developers must navigate. Because the model distributes probability among provided options even when none fits, Google advises setting confidence thresholds, implementing separate scope checks, or including explicit catch-all categories. Furthermore, because user text can argue for its own classification, developers are urged to establish rigorous criteria and utilize secondary checks or human oversight for critical actions like financial payouts.

Why it matters

The introduction of a structured decision endpoint alters how software interacts with large models by eliminating the need to parse natural language responses. Developers gain a faster, cheaper method to automate content scoring and policy enforcement, which directly impacts operational efficiency and system latency across digital platforms.
