xAI is promoting Grok 3 as the best model on the market, claiming it surpassed competitors from OpenAI, Google, Anthropic, and DeepSeek on key benchmarks. Grok 3 did perform well under the codename "chocolate" in Chatbot Arena, which pits chatbots against each other in blind performance tests.

AI on Monday unveiled its updated Grok 3 artificial intelligence model, as the Elon Musk-led startup pushes to keep pace with the advanced reasoning and search capabilities in competitors’ models.

While company owner Elon Musk expanded on that a bit during an official Grok 3 launch video on the social media platform, one key detail was omitted: the price. It has now been revealed that X’s highest level subscription tier – X Premium+ – has been increased substantially in price, with US users required to pay $40 each month for its benefits.
