Smallest.ai

Overview

Smallest.ai is a San Francisco AI research lab building ultra-low-latency, full-duplex enterprise conversational voice AI (Voice 4.0 / Hydra speech-to-speech). Founded late 2024 by Sudarshan Kamath and Akshat Mandloi. Focuses on real-time interruptible conversation with handoff to large LLMs — not media dubbing.
