XAI, Elon Musk’s AI company, may be embroiled in an escalating lawsuit with OpenAI. But that’s not stopping it from shipping new products — on a Friday night, no less.

This evening, xAI revealed that it has begun to roll out an upgraded version of its flagship Grok 2 chatbot model to all users on X, the social network formerly known as Twitter. (X, which Musk also owns, often serves as a testing ground of sorts for Grok.) The enhanced Grok is “three times faster,” xAI claims in a blog post, and offers “improved accuracy, instruction-following, and multi-lingual capabilities.”

Free users can only ask Grok ten questions every two hours. Subscribers to X’s Premium and Premium+ plans get higher usage limits.

XAI also announced tonight the addition of a “Grok button” to X, which the company says is designed to help users discover “relevant context, understand real-time events, and dive deeper into trending discussions.”

And the startup said it’s making several changes to its enterprise API.

XAI’s API has a pair of new Grok models with better efficiency and multilingual performance, xAI says. As a result of the efficiency gains, pricing has been reduced from $5 per million input tokens (~750,000 words) or $15 per million output tokens to $2 per million input tokens and $10 per million output tokens.

In the coming weeks, xAI’s image generation model, Aurora, will come to the API as well, xAI says. Aurora, a largely unfiltered image AI, was released on X this month in the Grok chatbot experience.
