Rather than scaling a single generic model to handle every task, Smallest trains compact, purpose-built models for speech synthesis, transcription, language understanding, and native speech-to-speech conversation — each optimized for its specific job. The result is faster inference, lower latency, and more efficient performance across voice-driven applications. ## Who It’s For Smallest AI is built for teams running high call volumes who need voice automation without sacrificing conversation quality — debt collection agencies, real estate teams, e-commerce support desks, and customer support operations. It also serves developers who want to build custom voice products on top of a fast, well-documented API, and early-stage startups building voice-first products from scratch. ## Core Models Model Function Key Spec [Lightning](https://smallest.ai/text-to-speech) Text-to-Speech ~100ms latency, 15+ languages, instant voice cloning [Pulse](https://smallest.ai/speech-to-text) Speech-to-Text 38+ languages, speaker & emotion detection, PII/PCI redaction Electron Small Language Model Sub-3B params, OpenAI-compatible API, sub-300ms TTFT [Hydra](https://smallest.ai/speech-to-speech) Speech-to-Speech Native full-duplex model, sub-300ms latency, early access **Lightning** delivers studio-quality audio at 44.1kHz with automatic language detection and mid-sentence code-switching, plus instant voice cloning from just 5-15 seconds of reference audio. **Pulse** offers accurate real-time transcription with built-in speaker diarization and redaction — no preprocessing required. **Electron** is purpose-built for voice agents, with voice-agent-specific behaviors like emitting filler phrases before tool calls so a conversation never goes silent mid-task. **Hydra** processes speech and text simultaneously in a single unified architecture, enabling true full-duplex conversation without the latency of a cascaded pipeline. ## Atoms: The No-Code Voice Agent Platform On top of these models sits [Atoms](https://smallest.ai/voice-agents), a no-code voice agent builder. Teams describe an agent’s role, conversational flow, and fallback behavior in plain language, and Atoms generates a working agent in about 30 seconds. It includes: - Knowledge base grounding from docs, FAQs, and product specs - Outbound calling campaigns with automatic retry logic - Telephony support in 40+ countries - Webhooks, post-call analytics, and prompt scoring - Mobile SDKs for iOS, Android, React Native, and Flutter A full conversational turn — transcription, reasoning, and spoken response — completes in **under 800ms** end to end. ## Use Cases - Automating debt collection calls with real-time negotiation and CRM sync - Real estate lead qualification and appointment scheduling - E-commerce customer support and cart-recovery follow-ups - Building multilingual voice assistants and conversational AI products - Voice cloning for audiobooks, gaming, and advertising - 24/7 inbound and outbound call center agents ## Security & Compliance Smallest AI is **SOC 2 Type II, HIPAA, GDPR, ISO 27001, and PCI-DSS compliant**, with on-premise deployment available for regulated industries like healthcare, finance, and debt collection — running inference directly on customer-owned hardware so no data leaves the customer’s infrastructure. ## Pricing Smallest AI offers a free tier with $10 in credits and no credit card required, followed by usage-based pricing on the [pricing page](https://smallest.ai/pricing). Custom Enterprise plans are available for teams needing SLA guarantees, dedicated support, and on-premise deployment. > Not one massive model that knows everything, but many small ones that each know exactly what matters. ## Overview ### Who is it for?
