What Model Odds is built for

Model Odds is made by the team that publishes this site. 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], so a developer can see the launch record. 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]. It runs three estimators side by side and publishes the spread between them as the error bar ^[3]. The estimate is based on the gaps between recent launches, and it takes into account how long the current wait has already lasted ^[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].
