# Grok TTS

> xAI's Grok TTS is a text-to-speech model available as a partner-hosted SKU on Cloudflare Workers AI. Converts text to spoken audio output.

**ID**: `x-ai/grok-tts`  
**Creator**: xAI  
**Category**: audio  
**Context**: Not published  
**Status**: Disabled (since 2026-07-26) — no longer routable or listed; kept for history/usage reference.  
**Reason**: The catalogue was narrowed to models whose output is text or embeddings; this model's output is audio (text-to-speech), so it was taken out of service. Related: #1551 (these SKUs bill $0 on a metered backend).  
**Pricing**: $15.00 per 1M characters of input text  
**Released**: 2026-06-04
