About this release
Mercury Voice is a diffusion-based LLM optimized for real-time voice agents. It supports low/medium/high reasoning effort, 128K context, tool calling, structured outputs, and long system prompts while achieving median time-to-first-token under 320 ms on production prompts. It is available to enterprise customers via the Inception API as an OpenAI-compatible endpoint and integrates with stacks like LiveKit, Pipecat, Vapi, and Retell.
