xAI Rolls Out Grok 4.3 Beta with Slide Creation Capabilities and New Speech-to-Text/Text-to-Speech APIs
The latest beta adds native presentation building and high-quality speech synthesis for developers.
xAI has rolled out a significant update with the Grok 4.3 Beta, headlined by two major new capabilities. First, the model now features native slide creation, allowing users to generate structured presentations directly from a prompt, a move that positions Grok as a more direct competitor to business-focused AI tools. Second, the company has launched new Speech-to-Text and Text-to-Speech APIs, offering developers fast, accurate transcription and natural, expressive multilingual voices through a simple pricing model.
This release builds on a rapid series of announcements from Elon Musk's AI venture, which recently secured a massive $20B Series E funding round and was acquired by SpaceX. The new features signal xAI's push to make Grok a more versatile, multimodal platform for both end-users and developers. The slide creation capability targets productivity workflows, while the voice APIs open doors for building conversational agents, accessibility tools, and interactive applications, expanding Grok's reach beyond text-based interactions.
