xAI Ships Voice Cloning API and Grok Imagine Agent Mode in a Single Day

xAI launched voice cloning via API — 80+ voices across 28 languages, custom clones in under two minutes — while simultaneously pushing its Grok Imagine agent mode into beta. The twin releases mark xAI's most aggressive push yet into multimodal infrastructure.

xAI made a double-barreled bid for developer attention on Friday, launching both a voice cloning API and the beta of Grok Imagine's agent mode within hours of each other. As @xai announced, the voice cloning product lets developers create custom voices in under two minutes or choose from a library of over 80 pre-built voices spanning 28 languages. Target use cases include voice agents, audiobooks, video game characters, and content production.
