About AI Stats
AI Stats, whose site is branded Phaseo, combines a catalog of AI models with a gateway for calling them. Users can discover and compare models, providers and rankings, then send requests through a single API that routes across providers, with the aim of keeping inference affordable and an integration portable.
The platform lists models, a chat interface, providers, apps, rankings and comparison tools, plus migration guides and a published methodology. Developers get documentation, an API reference, a quickstart, SDKs and API keys, and the gateway is described as OpenAI-compatible with monitoring of usage, pricing and reliability. The project describes itself as open source with a public GitHub repository, so teams can inspect and extend the gateway. A hosted version is available with sign-up and a pricing page, and the site includes status information and community channels such as Discord.
