OpenAI opens Decisions API to all customers
What happened
TechCrunch reported on October 23, 2026 that OpenAI opened its Decisions API to all customers on Thursday, adding voice and vision modality support to the public version to speed up inference and cut the cost of handling decision tasks. OpenAI says response time fell from one to three seconds to 100, 120 and 180 milliseconds; after Speak adopted it, action intervals dropped from 1.4 seconds to 0.13 seconds. On the model behind it, earlier reports said the service was reconfigured from ChatGPT Luna, and a later first-party OpenAI report says it is based on GPT-6 Luna. OpenAI also says that for decisions with a bounded set of answers, the API is up to 10 times faster than using GPT-6 Luna through the Responses API. The service is now fully open.
