We reported yesterday the launch of the Grok 3 chatbot, which is only available if you have an X Premium+ subscription. That cost $22/month at the time, but thats now been more than doubled to $50/month though X seems a little confused about its own prices X owner Elon Musk claims Grok 3 is the smartest AI on Earth, as competition continues to increase. OpenAI is planning to launch its most powerful model yet, GPT-4.5m within the next few weeks.X Premium+ subscription doubledAccess to the latest Grok model is limited to X Premium+ subscribers, and Musk appears to think they are willing to pay a lot more for it. TechCrunch spotted the immediate price increase.Hours after Elon Musks AI company, xAI released the latest version of its AI model, Grok 3, X has significantly hiked the price for its top Premium+ subscription plan, which gives users access to the latest model, to almost $50 per month []This is the second time X is raising the price for the Premium+ plan in the past couple of months. In December, the company hiked the subscription amount to $22 per month from $16 per month. If we go by any of the listed prices, the new plan will cost Premium+ subscribers more than double what they currently pay.Even then, you wont get access to all of Grok 3s features some of them require a standalone SuperGrok plan.Pricing confusionHowever, the sites Ivan Mehta notes that X seems confused about its own pricing.When this reporter tried to sign up for the Premium+ plan, X showed that it would cost $39.83 per month ($477.95 annually), though the final check-out page said it would cost $395 for a year.Also, while Xs support page says a monthly subscription costs $50, the sign-up page lists a $48.40 per month price, and the check-out page is charging $40 a month.So, er, youll pay more; how much more appears to be something of a lucky dip. Maybe the company should have a smart AI look into it.Photo byMariia ShalabaievaonUnsplashAdd 9to5Mac to your Google News feed. FTC: We use income earning auto affiliate links.
