Pricing FAQ

How does Ultravox achieve sub-300ms latency?

Ultravox processes speech natively through audio embeddings rather than converting to text and back. This speech-native approach eliminates the latency bottlenecks inherent in traditional ASR-to-LLM-to-TTS pipelines, enabling truly real-time conversational interactions.

What makes Ultravox 3x cheaper than GPT-4o Realtime?

Ultravox leverages open-weight models and efficient infrastructure to offer pricing at $0.05/minute compared to GPT-4o Realtime's $0.15/minute. The open-source approach reduces licensing costs while maintaining comparable performance and features.

Can Ultravox integrate with existing business systems?

Yes, Ultravox supports comprehensive tool calling capabilities that enable voice agents to execute functions, access databases, trigger workflows, and interact with APIs in real-time during conversations.

Is Ultravox suitable for enterprise deployment?

Absolutely. Ultravox supports unlimited concurrency on Pro and Enterprise tiers, offers on-premise deployment options, provides enterprise security features, and includes dedicated support for large-scale implementations.
