# Grok voice model and Grok 4.6 updates arrive

> xAI is keeping up a punishing release cadence. The company has shipped Grok Voice Think Fast 2.0, a speech-to-speech model priced at 0.08 dollars per minute that it says offers stronger reasoning, faster responses, and smoother back-and-forth conversation. Alongside it, xAI confirmed that Grok 4.6 is due within two weeks and Grok 4.7 shortly after, both by the end of August. The update also touches developer surfaces. Grok Build gains command-line control for MCP servers, faster cold starts, and better session handling, while web search now supports an explicit image search option. Taken together it is less a single marquee launch than a steady drumbeat of incremental upgrades across voice, tooling, and search. That pace is the story in itself. Elon Musk has made rapid iteration a competitive weapon, pushing out models and features faster than rivals can fully digest them. Whether speed translates into a durable quality edge is an open question, but xAI is clearly betting that shipping constantly keeps it in the frontier conversation.
