About Featherless
Featherless is a serverless AI inference platform that makes tens of thousands of open-source AI models instantly available through a single API.
We believe the future of AI is open. Our job is to be the neutral layer for open models — independent of any hyperscaler or proprietary ecosystem — so that any model, from any creator, is one API call away.
From research lab to the home of open models
Featherless started as a research team, not an infrastructure company. Our founders co-led RWKV, the Linux Foundation project behind one of the most significant open-source model architectures — an attention-free design that made frontier-scale AI radically cheaper to run.
Getting those models into production revealed the real bottleneck: hundreds of thousands of open models exist, but almost none of them are easy to run. We built Featherless to close that gap. The company began as Recursal.AI — today the name is Featherless, and the same research DNA drives everything we ship.
