Eugene Cheah Is Asking AI’s Most Expensive Question: How Small Can We Go?
The Featherless AI co-founder turned a side-door pricing test into an open-model platform. His bigger wager is stranger and more consequential: useful intelligence should be smaller, steadier and owned by more people.
Featherless AI
Featherless AI is a serverless inference platform that gives developers and enterprises a single API key to run more than 40,000 open-weight AI models across language, vision, audio and multimodal tasks - without provisioning or managing any GPUs. Founded in 2023 by the team behind the RWKV open-source model architecture, the company sells flat-rate subscriptions with unlimited tokens and positions itself as a neutral infrastructure layer for open-source AI, independent of the major cloud hyperscalers. It raised a $20M Series A in April 2026 co-led by AMD Ventures and Airbus Ventures, bringing total funding to about $25M.
