xAI launched Grok 4.3, a new large language model, and a voice cloning suite on the web. The move comes as Elon Musk's company ramps up competition with OpenAI while Musk faces Musk faces OpenAI co-founder Sam Altman in court.
Grok 4.3 arrives with aggressive pricing designed to undercut rivals. The voice cloning suite allows users to generate synthetic voices at scale, adding a new capability to xAI's product lineup.
The launches follow internal turmoil at xAI, which saw the departure of Musk's original co-founders in recent months. Despite the setbacks, the company continues shipping new products to challenge OpenAI's market position.
xAI has positioned itself as an alternative to OpenAI since its founding. The dual release signals the company's intent to compete across multiple AI modalities. Voice cloning technology represents a competitive frontier as major AI labs race to offer multimodal capabilities.
The timing reflects xAI's strategy to maintain momentum despite leadership challenges. Both products are available immediately through xAI's web console and API access.
