Musk's xAI unveils Grok 4 with a $300 subscription for the premium version
xAI has stated that Grok 4 surpassed competitors scoring 25.4% on Humanity's Last Exam without 'tools' beating out Gemini 2.5 Pro (21.6%) and OpenAI's o3 which scored 21%. The benchmark comprises more than 2,500 questions on dozens of subjects including maths, science and linguistics.
The AI model will also be able to analyse images and respond to questions.
Meanwhile, Grok 4 Heavy is their multi-agent variant that shows better performance. The company claimed that the model's multiple agents work together on problem and then compare their results to determine the best outcome.
Grok 4 Heavy scored 44.4% on the Humanity's Last Exam benchmark, outperforming Gemini 2.5 Pro's 26.9%.
'Grok 4 is the first time, in my experience, that an AI has been able to solve difficult, real-world engineering questions where the answers cannot be found anywhere on the Internet or in books. And it will get much better,' Musk posted on X.
The release comes during a rocky time for both X and xAI. Just yesterday, X CEO Linda Yaccarino resigned from her position after a two-year tenure.
Earlier this week, Grok started spewing antimsemitic comments on X a day after Musk expressed that the chatbot was becoming too 'biased' and politically correct. The posts were later removed after a furore.

ChatGPT may be a little different now as OpenAI rolls out a new ‘warmer and friendlier' update
OpenAI has announced that it has made the new GPT-5 AI model more 'warmer and friendlier' following initial feedback that the model felt too formal. The AI startup says that while the changes are subtle, GPT-5–powered ChatGPT should now feel more approachable. Despite adding some light flattery in the model with gestures like 'Good question' and 'Great start,' OpenAI says GPT-5 shows no increase in sycophancy (being overly agreeable with users) compared to the earlier GPT-5 personality. The new update is rolling out to all users and should take about a day to complete. Meanwhile, head of ChatGPT Nick Turley said that users can further customize ChatGPT's personality through the Custom Instructions settings. He also hinted at new upcoming ways to tailor ChatGPT's personality according to user preference. Notably, OpenAI also provides an option to choose from four different personalities — Cynic, Robot, Listener, and Nerd — to tailor GPT-5's responses. However, this feature is currently restricted to paying customers and does not apply to the free tier of the app. OpenAI had high hopes for its GPT-5 rollout, with CEO Sam Altman creating significant hype around the new AI model in the past few months. However, when the model finally launched last week, it was met with anything but a warm reception from users. ChatGPT users complained that GPT-5's responses were shorter and seemed to lack the emotional depth of the previous model. Just a few months ago, OpenAI faced criticism for making GPT-4o too sycophantic, but this time, its new model received backlash for almost the opposite reasons. Another major reason the GPT-5 launch fell flat was user frustration over the removal of all older AI models from ChatGPT. This not only disrupted workflows for many but also reduced usage limits for $20/month ChatGPT Plus subscribers, who went up in arms and threatened to cancel their subscriptions. OpenAI then increased the rate limits for ChatGPT Plus users, first for the standard model and later for the GPT-5 Thinking model as well. The company also brought back the model picker in ChatGPT to allow users to select which AI model should answer their queries.

OpenAI staff plan to sell $6 billion in stock to SoftBank, other investors
Current and former OpenAI employees plan to sell approximately $6 billion worth of shares to an investor group that includes Thrive Capital, SoftBank Group Corp. and Dragoneer Investment Group, in a deal that values the ChatGPT maker at $500 billion, according to people familiar with the matter. The talks are early and the size of the share sale could still change, said the people, who asked not to be identified discussing private information. The secondary share investment is on top of SoftBank's commitment to lead OpenAI's $40 billion funding round, which values the company at $300 billion, according to another person familiar with the deal. That round remains ongoing, with OpenAI recently securing $8.3 billion from a syndicate of investors. Representatives for Dragoneer and Thrive didn't respond to requests for comment. Spokespeople for OpenAI and SoftBank declined to comment. All three firms are existing OpenAI backers. Allowing employees to sell shares is an important tool for startups trying to retain top talent, without requiring the company to go public or be acquired. In some cases, early investors also use these deals to sell down their stakes, though OpenAI investors are not eligible to do so in this round, according to a person familiar with the matter. Current and former employees who spent at least two years at the company are able to participate. With its participation in the share sale, as well as its previous commitments, SoftBank is making a pivotal bet on the success of OpenAI. In addition to those deals, the Japanese conglomerate headed by Masayoshi Son recently closed a separate $1 billion purchase of OpenAI employee shares at a $300 billion valuation, according to a person familiar with the matter. Negotiations for that deal started before talks around the $500 billion secondary valuation began, they said. The $500 billion valuation would make OpenAI the world's most valuable startup, surpassing Elon Musk's SpaceX. The company expects revenue to triple this year to $12.7 billion, up from $3.7 billion in 2024, Bloomberg has reported. And the secondary deal talks come on the heels of the release of its highly-anticipated GPT-5 model. This week, OpenAI chief Sam Altman sat down with a group of reporters and shared his vision for the company, including that it wants to spend trillions of dollars on the infrastructure required to run AI services in the 'not very distant future.' 'You should expect a bunch of economists to wring their hands and say, 'This is so crazy, it's so reckless,' and whatever,' Altman said. 'And we'll just be like, 'You know what? Let us do our thing.''
