Voice AI platform offering low-latency TTS, STT, and speech-to-speech models plus an agent builder for developers.
What it does
Smallest AI builds compact, specialized voice models rather than one large general model, arguing that small, task-specific models can match or beat larger systems while running faster and cheaper. Its product suite includes real-time text-to-speech, speech-to-text, a small language model, and a native speech-to-speech model, all accessible through a single agent-building platform.
