OpenAI launches Decisions API (public beta) using gpt-6-luna

OpenAI introduced the Decisions API in public beta, a service that evaluates text, images, or both and returns structured outputs (yes/no probabilities, category picks, or scale ratings). It uses only gpt-6-luna, is roughly ten times faster than the Responses API, charges $0.10 per million input tokens (output tokens free), supports zero-data retention and HIPAA-compliant use in the US and Europe, and comes alongside a simplified paid tiering (Build, Launch, Grow) with $500/$5,000/$200,000 monthly thresholds.

OpenAI unveils GPT-6.1 Sol, Agents API 'computer use', cloud Codex, and Decisions API at DevDay 2026

At DevDay 2026 OpenAI announced GPT-6.1 Sol (an update to GPT-6 Sol aimed at coding and professional tasks), expanded Agents API support so agents can operate software via graphical interfaces, cloud-based Codex environments and CLI updates, a limited-preview Decisions API using the smaller Luna model for selecting predefined answers, and expanded ChatGPT plugin capabilities plus new persistent-agent features (Dots) and a shared workspace (ChatGPT Space). OpenAI said GPT-6.1 Sol approaches GPT-6 Astra on several evaluations and is priced at about one-fifth of Astra’s standard I/O token prices, with cached input costing $0.10 per million tokens; some features are available only on selected plans or limited preview.

OpenAI previews Decisions API — a Jev-like fast decision model for Luna

At its Dev Day, OpenAI’s CEO Sam Altman revealed the Decisions API, a limited-preview product that lets the Luna model output probabilities over a predefined set of choices (e.g., classifications or agent behaviors) at high speed and low cost. Media and industry observers note the API resembles TypeSafe AI’s recently released Jev; proponents say such decision-focused models could cheaply monitor or gate agentic actions, though exact capabilities and calibration remain unclear.
