smallest.ai is a voice AI platform for building real-time speech systems, voice agents, and production-grade audio applications. It offers a suite of specialized models for text-to-speech, speech-to-text, speech-to-speech, voice cloning, and small language models, all designed around low latency, efficiency, and enterprise scalability.

The platform’s core thesis is that the future of AI will rely on smaller, specialized models rather than one massive general-purpose system. smallest.ai applies this philosophy to voice, using compact, efficient models that can process speech quickly, adapt to specific use cases, and support real-time interaction across industries like healthcare, debt collection, real estate, e-commerce, small business, and customer support.

smallest.ai includes several production models: Lightning for fast text-to-speech, Pulse for real-time speech-to-text, Hydra for native speech-to-speech, and Electron as a sub-3B small language model. Lightning supports studio-quality speech with low latency and multilingual output, Pulse provides transcription across 38+ languages with diarization and emotion detection, and Hydra is designed for full-duplex speech-to-speech conversations that can handle interruptions and natural conversational flow.

Beyond APIs, smallest.ai also provides an agent-building platform for launching voice agents in minutes. Teams can create agents, upload knowledge bases, manage campaigns, rent or connect phone numbers, configure retry logic, track versions, and deploy at scale. With SOC 2 Type 2, ISO 27001, GDPR, and HIPAA compliance, the platform is positioned for production voice AI workflows where security, reliability, and real-time performance matter.
