Poolside
Poolside is an AI foundation model lab (founded 2023 by former GitHub CTO Jason Warner and Eiso Kant) building open-weight foundation models - the Laguna family - purpose-built for agentic software engineering. Poolside does not run a shared public SaaS API the way OpenAI or Groq do. Instead it publishes a full, public API reference (docs.poolside.ai) for an OpenAI-compatible inference API plus an admin/identity API, but the API itself only comes alive once a customer has a provisioned Poolside deployment - into their own AWS/Azure/Google Cloud VPC, on customer-owned NVIDIA GPU clusters via Helm, or fully air-gapped on-prem. There is no public signup page, free tier, or published pricing; access is arranged directly with Poolside's sales team. Separately, Poolside's smaller open-weight model, Laguna XS 2.1, can be called by anyone through third-party inference hosts such as OpenRouter, which is the closest thing to a public, self-serve way to hit a Poolside model over HTTP.
