Orion by OpenAI (never released)

There is no product called Orion. The name circulated in press reporting during 2024 as an internal OpenAI codename, and this page treated that reporting as a product launch. We are leaving the page up, corrected, rather than deleting it, because people still search the name and most of what they will find repeats the same rumours as fact. What we published here was wrong in a specific and avoidable way. This listing carried a context length, a hallucination-reduction percentage, a reasoning multiple, and a description of a research-preview access programme. None of them came from OpenAI. openai.com/orion returns 404, the name appears nowhere in OpenAI's model documentation, and it is absent from the GPT-5 announcement. We had the listing classified as free, which told readers they could go and use it, and because our detail pages attach an offer to anything free, we were also publishing structured data to search engines declaring an offer at $0.00. What OpenAI has actually shipped is documented at platform.openai.com under the model names it uses publicly. If you came here after reading that Orion was imminent, the honest summary is that reporting on unreleased frontier models is frequently wrong about names, timing and capability, and that a directory repeating it adds nothing except the appearance of confirmation. This page will be rewritten as a product listing if OpenAI ever releases something under this name, and not before. Browse AI solutions.
