Hi everyone!

Chatting with Grok's Voice Mode is honestly a fascinating experience. The voices are just so vivid and full of personality that it makes talking to AI feel genuinely engaging.

Now xAI is opening this exact stack to developers. You get access to the same native audio models that power millions of Teslas. It handles interruptions incredibly well and supports native tool use like Web search right out of the box.

The pricing is also very interesting. At a flat rate of $0.05 per minute, it is one of the most competitive options among tier-1 voice APIs.

For those who might worry about Grok's "edgy" personality, don't be. The API gives you full control via system prompts. You get the world-class voice quality with whatever personality you define for your app.

Give it a try in the playground!
