Inception drops Mercury Voice, a 320ms diffusion LLM for voice agents
Inception Labs just rolled out Mercury Voice for enterprise customers, a diffusion LLM tuned specifically for conversational agents. It hits a median time to first answer token of 320 milliseconds—5.9x faster than GPT-6 Luna—without sacrificing tool-calling and reasoning performance. It drops straight into OpenAI-compatible voice pipelines, effectively killing the awkward pause in phone agents.
