What Model Odds is built for

Model Odds is made by the team that publishes this site. It is a website with a public API ^[3], and it ranks every Anthropic and OpenAI model family by its estimated chance of a release within 30 days ^[3]. Anthropic and OpenAI each get their own page that lists every past release ^[3]. Each past launch the model uses has to be confirmed by an official post and an independent timeline, and it is listed with its date ^[3].

The estimate is fitted on the gaps between recent launches and takes into account how long the current wait has already lasted ^[3]. It runs three separate estimates side by side and shows how far apart they are ^[3]. Signals read automatically from company SDKs and docs, and from third-party model catalogues when two of them agree, can only raise the odds ^[3]. The estimator can replay any past date without using data from after that date ^[3]. The public API serves odds, the launch record and service health ^[3]. You can sign up with a confirmed email to get alerts, and every subscriber gets every company's new releases at the same time ^[3].

Pricing and fees
