How much did X increase its premium subscription price after unveiling Grok3?

Following the unveiling of Elon Musk's new chatbot Grok3, X AI significantly increased the price of its premium plus subscription by more than 80%. The subscription cost jumped to $40, representing a substantial price hike that coincided with the launch of the new AI model. This price increase appears strategically timed with Musk's claims about Grok3's superior capabilities compared to competitors like ChatGPT, suggesting the company believes the new technology justifies the higher subscription cost.
