Smallest AI

Smallest AI is a voice AI company that builds fast, compact models for real time speech and conversation. It focuses on turning text into speech, speech into text, and full speech to speech conversations with very low delay, so voice agents sound natural and respond quickly.

The platform includes Lightning for text to speech, Pulse for speech to text, Hydra for speech to speech, and Electron, a small language model built for reasoning inside voice conversations.

On top of these models sits Atoms, a no-code platform for building, testing, and deploying voice agents for support, sales, and outbound calling.

Pricing follows a pay as you go model, with a custom Enterprise plan for larger teams needing dedicated infrastructure and support.
