Smallest AI is a voice AI company that builds compact, low-latency speech and language models for real-time voice applications. The company develops and operates a platform of proprietary models — including Lightning (text-to-speech), Pulse (speech-to-text), Hydra (speech-to-speech), and Electron (a sub-3-billion-parameter small language model) — that power production voice agents and multimodal AI across industries such as healthcare, financial services, debt collection, real estate, e-commerce, and customer support. The company's approach is built on small, specialized models rather than a single large general-purpose model, optimizing for speed, accuracy, and cost at production scale. Smallest AI provides self-serve APIs for developers as well as enterprise deployments, including on-premise and private cloud options. Smallest AI operates with enterprise-grade security and is SOC 2 Type 2 compliant, ISO 27001 certified, GDPR compliant, and HIPAA compliant, making its platform suitable for regulated and high-trust environments. The company is headquartered in San Francisco, California.
