About

The Grok Voice Agent API is xAI’s new developer platform for building fast, intelligent, and multilingual voice agents. It is powered by the same in-house voice technology used by Grok Voice in mobile apps and Tesla vehicles. The API enables voice agents to speak dozens of languages, call tools, and search real-time data. Grok Voice Agents are engineered for low latency, delivering audio responses in under one second. The platform ranks first on the Big Bench Audio benchmark for voice reasoning performance. Developers benefit from a simple, flat pricing model based on connection time. The Grok Voice Agent API brings production-proven voice intelligence to custom applications.

About

Hermes is the operating platform for AI voice agencies. It replaces the Retell + GoHighLevel + Zapier + Stripe + Twilio + developer stack with one white-label platform agencies use to deploy, manage, and scale voice agents under their own brand. Built-in CRM, campaign orchestration, and transparent usage-based billing mean your clients never see the word Hermes. Launch your first agent in 72 hours and run 80%+ margins on every client you serve. Plans from $149/mo (3 workspaces, 300 included minutes) to $699/mo (20 workspaces, 2,000 minutes), with flat $0.24/min overage and a Contact Us tier for enterprise. Built by builders, for builders.
