Featherless AI
Serverless LLM inference across thousands of open-weight models via one API.
About
Featherless AI is a serverless inference platform that serves thousands of open-weight models from the Hugging Face catalog behind a single OpenAI-compatible REST API. It exposes chat completions, text completions, and embeddings endpoints with streaming, tool calling, and vision support.
The platform differentiates on flat monthly subscription pricing with unlimited tokens rather than per-token billing, starting at $10 per month, plus sub-second model loading and predictive autoscaling on H100 and A100 clusters. Press coverage reports a $20M raise to expand its open-source AI infrastructure, and it integrates with LiteLLM, LangChain, and agent frameworks like OpenHands.
