I was scanning through all this type of news, but a video from yesterday's launch event of Grok4 demonstrating AI dialog live was pretty amazing, so I'm going to screenshot this one for you:

Grok 4's new voice assistant “Eve” is not just able to carry on a conversation, it can also express emotions, have changes in tone, improvise and sing, and even sang an improvised “Diet Coke aria” in an elegant British accent, like a stage actor performing in a London theater.

It feels like Grok4's AI voice function has been completely anthropomorphized, as if it is chatting with a human being, without the taste of AI at all, which is really quite impressive.

At the launch event, Grok4 and ChatGpt had a PK session on AI voice function, both of them took turns to repeat the numbers, and ChatGPT “grabbed the answer” from time to time, a bit like a classmate who took the question without hearing it clearly. Grok's performance is smoother and closer to human speech habits, and will not interrupt the user.

Grok Chinese name “Grok”, URL: grok.com, now Grok4 has been fully online, not open to free users, Grok 4 subscription fee is $ 30 / month, Grok 4 Heavy costs $ 300 / month, Grok 3 to maintain free status.

Yes, Grok 4 is the most expensive AI on the market today, with annual subscription prices topping out at $3,000, well ahead of ChatGpt and Google Gemini.

Of course, Musk also invested a lot of resources in Grok, knowing that in the field of AI, xAI has always been known as “luxury”, with 100,000 H100 GPUs containing "the world's supercomputer. Grok4's RL computation is more than 10 times that of any other model.

Grok 4 is not only the most articulate AI and the most expensive AI, it is also the smartest AI available.

Musk says that Grok 4 surpasses the PhD level in all disciplines. Although it does not yet have the ability to invent new theories or come up with original technologies, in his opinion, it is only a matter of time.

Musk also boasted that by the end of this year Grok might be able to invent new technologies, and next year it will almost certainly have the ability to discover new laws of physics.

Grok 4 demonstrated several scenarios of its capabilities at the launch event. For example, Grok4 predicted the probability of winning this year's MLB World Series, assessing the Los Angeles Dodgers' probability of winning at 21.6 percent.

Grok4 is the smartest AI out there, mainly because it scored 45% on the HLE test, which is first place and much higher than the Gemini 2.5 Pro's 26.9%.

HLE is the abbreviation of Humanity's Last Exam, meaning the last exam for human beings, covering more than 100 disciplines such as math, physics, computers, medicine, humanities and social sciences, etc. The test is extremely difficult to truly reflect the model's comprehensive performance in general knowledge and complex reasoning.

In real-world scenarios, Grok-4's performance is also noteworthy, such as being ranked No. 1 on the Automated Retail Bench.

In Musk's favorite area of gaming, Grok-4 can now complete a first-person shooter in just four hours.

Although Musk boasts about Grok4, it's still hard to shake ChatGpt's position as the leading big brother. At present, among the three AI giants, ChatGpt ranks first, Google Gemini second, and Grok can only rank third.

However, Musk's advertising effect is still very strong, he can always find some points to compare with others, and in recent times Grok's users have grown very quickly.

Grok users in China are even less, I sometimes use Grok, I tell you, this guy is actually quite smart, but there are a lot of “crooked talent”, some people commented that Grok “three views are not correct”, worrying that Grok4 will be powerful and will harm society. Some people say that Grok is “unorthodox” and worry that if Grok4 becomes powerful, it will endanger society.

This argument is also a bit reasonable, you have used Grok know that its content restrictions are not so strict, some questions you can not ask the answer on other AI, you can find Grok4 try, such as the latest nodes every day ah, such as the transfer of payments outside the country ah, it will tell you the answer.

Of course, the serious AI features Grok is not bad, such as the free use of Grok3 can also generate images, as long as the dialog box to enter “generate images, ……” followed by the prompt word written on the picture, Grok3 will be generated each time two Grok3 will generate two pictures at a time.

Grok4 is introduced here, although we can not use the free users, but to understand the new information is also necessary, you say right?
