Smallest AI

Smallest AI is a real-time voice AI platform built on smaller, specialized models instead of one massive general-purpose system — designed for faster, more efficient performance in speech synthesis, transcription, and conversational voice agents. The platform includes four core models: Lightning (text-to-speech at ~100ms latency across 15+ languages, with instant voice cloning from 5-15 seconds of audio), Pulse (speech-to-text with speaker and emotion detection across 38+ languages), Electron (a sub-3B parameter LLM optimized for voice agents with an OpenAI-compatible API), and Hydra (one of the first native speech-to-speech models built for production). Atoms, the no-code voice agent builder, lets teams deploy production voice agents in minutes with knowledge base grounding, outbound calling campaigns, and telephony in 40+ countries — completing a full conversational turn in under 800ms. Smallest AI is SOC 2 Type II, HIPAA, GDPR, ISO 27001, and PCI-DSS compliant, with on-premise deployment for regulated industries like healthcare, finance, and debt collection.
