OpenAI Decisions API Hits Public Beta With 10x Faster Typed Answers
OpenAI has released the Decisions API in public beta. It turns text and images into typed answers your code can branch on. OpenAI team states the OpenAI Decisions API runs about 10x faster than the Responses API. It targets a common pattern: prompt an LLM, then parse its text into a label. TL;DR Size: GPT-6 Luna parameter count is not disclosed. Its model card lists a 1,050,000-token context window. Runs on: OpenAI-hosted API only, via POST /v1/decisions. No open weights, no self-host
Get smart on it
OpenAI has released the Decisions API in public beta, which evaluates text and images to return typed answers rather than prose text. The API is designed to handle a common pattern of prompting a language model and then parsing its response into structured labels, and it runs about 10x faster than the standard Responses API. Input costs $0.10 per 1 million tokens with no output charges, and currently only supports one model with general availability expected in the coming weeks. The API offers three question types: predicates that return probabilities, choices that pick from supplied options, and scores that rate input against ordered levels.

What is Decision 3.0? vLLM Semantic Router’s New Open Decision Models
The vLLM Semantic Router team has released Decision 3.0, a family of multimodal decision models. Decision 3.0 multimodal decision models read text, JSON and images, then answer typed questions about them. There are 5 sizes, from 0.8B to 27B, all under Apache-2.0. For developers, this is a fast way to classify, route and gate requests without parsing generated text. TL;DR Size: 5 models: d3-lite (0.85B), d3-nano (2.21B), d3-mini (4.54B), d3-flash (8.39B), d3 (26.09B). Context length: not
