On Thursday, the U.S. General Services Administration (GSA) made an announcement stating that Elon Musk's xAI firm has inked a fresh deal. This agreement is set to broaden the range of applications for its artificial intelligence chatbot, Grok, within the federal government. As per the GSA's clarification, from this point forward until March 2027, federal agencies have the option to procure the Grok AI model at a cost of $0.42 per agency. This price is significantly more budget - friendly compared to the $1 annual fee that Musk's chief rival, OpenAI, levies on government agencies for its ChatGPT product.
