Model Odds ranks every Anthropic and OpenAI model family by its estimated chance of a release [^2]. On needs, Manifold's page says users can browse markets in categories including politics, technology, sports, culture, business and fun [^1]. Model Odds' claims cover a model-by-model release odds ranking [^2], a verified launch record with dates [^2] and a public API that serves per-line odds, the launch record and service health [^2]. ## What Manifold is built for Manifold's own page says new users are given 1,000 Mana to start trading [^1]. Manifold is operated by Manifold Markets, Inc. [^1]. Its page mentions Mana Perps [^1]. Its page lets users browse markets in categories including politics, technology, sports, culture, business and fun [^1]. The facts here describe Manifold as a trading venue with categories and a starting credit, but they do not say how its markets are priced, how a developer would use it for release tracking, or whether it tracks AI model launches specifically. Check its own pages for those details. ## 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 [^2]. Anthropic and OpenAI each get their own page that lists every past release [^2]. 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 [^2]. It runs three estimators side by side and publishes the spread between them as the error bar [^2]. The estimate looks at the gaps between recent launches and at how long the current wait has already lasted [^2]. Signals read automatically from company software kits (SDKs) and documentation, and from third-party model catalogues when two of them agree, can only raise the odds [^2]. You can run the estimator for any past date, using only data available up to that date [^2]. ## Pricing and fees Manifold's page says new users are given 1,000 Mana to start trading [^1]. Mana is the trading credit that Manifold's page says new users are given [^1]. No dollar price, fee or paid plan for Manifold is published in the facts used here, so none is given on this page. [^1] Model Odds is free, and so is its API, with no account needed [^2]. It is a website with a public API [^2]. ## Setting it up and daily use Manifold's page says new users are given 1,000 Mana to start trading [^1].
