    About Smallest.ai

    Smallest.ai: Real-time Voice AI, Built to Scale

    Smallest.ai is an artificial intelligence platform focused on driving the future of small, efficient multi-modal models. The platform develops models under 10 billion parameters that are designed to outperform larger language models while utilizing dramatically lower GPU usage and achieving ultra-low latencies.

    Key Features

    • Lightning Text-to-Speech: Generates hyper-realistic audio in over 30 languages with thousands of local accents, voice cloning, and a time-to-first-byte as low as 100ms.
    • Electron Small Language Model: A conversational model with less than 3 billion parameters, featuring a 45ms time-to-first-token and built-in protection against NSFW content and prompt attacks.
    • Pulse Speech-to-Text: Transcribes audio across 38+ languages with code-switching, emotion detection, speaker identification, and interruption handling.
    • Hydra Speech-to-Speech: A full-duplex multimodal model supporting long context, tool calling, and highly emotional human-like voices.
    • Atoms Agentic Platform: Allows users to create, test, deploy, and analyze self-learning multi-modal AI agents across voice, email, chat, and social channels.
    • Enterprise Security: Secured by SOC 2 Type 2, HIPAA, PCI, GDPR, and ISO-aligned compliance standards.
    • Developer SDKs: Provides Node.js and Python SDKs for building and orchestrating AI workflows.

    Use Cases

    • Conversational AI: B2C notetakers, AI companions, AI celebrity clones, B2B collections, lead qualifications, and customer support.
    • Edge Computing: Custom chips, specialized hardware, and mobile devices.
    • Enterprise Production: High-volume production use-cases handling billions of conversations with sub-400ms average latency.
