Google CEO Sundar Pichai lauds Elon Musk on Grok 4 launch: 'Impressive Progress'
The brief interaction came as Grok 4 was introduced as a significant step forward for xAI, Musk's artificial intelligence startup, which aims to directly compete with leading players such as Google DeepMind, OpenAI, and Anthropic in developing cutting-edge large language models.
According to Musk, Grok 4 offers improvements across key metrics, including faster response times, multimodal capabilities, and enhanced integration with X's subscription ecosystem. The model is also touted as being more capable in subjects like mathematics and physics. Musk claimed Grok 4 'essentially never gets math/physics exam questions wrong, unless they are skillfully adversarial,' and said it can also detect and correct errors in ambiguously worded questions.
The timing of the launch is especially notable given the increasing competition in the AI race. Google, for its part, recently rolled out Gemini 2.5, expanding the reach of its AI across Search, Workspace, and Android.
Musk, a co-founder of OpenAI who has since distanced himself from the organisation, has often positioned Grok as an uncensored, more independent alternative to other mainstream AI offerings. His aim with xAI is to develop models that align with what he describes as "maximally truth-seeking" goals, avoiding what he perceives as over-filtering and bias in rival systems.
While Pichai's comment was short, it signals a rare moment of mutual recognition in an increasingly high-stakes and competitive sector. It also underscores the level of attention Grok 4 is drawing as xAI positions itself as a serious contender in the generative AI space.

Google hires Windsurf CEO and researchers to advance AI ambitions
Alphabet's Google has hired several key staff members from AI code generation startup Windsurf, a Google spokesperson said on Friday, in a surprise move following an attempt by its rival OpenAI to acquire the startup. Windsurf CEO Varun Mohan, co-founder Douglas Chen, and select members of the coding tool's research and development team will join Google's DeepMind artificial intelligence division, the Google spokesperson said. The former Windsurf team will focus on agentic coding initiatives at Google DeepMind, primarily working on the Gemini project. ChatGPT maker OpenAI was in talks to buy Windsurf, one of the hottest startups disrupting software development, sources familiar with the matter told Reuters in June. OpenAI could not immediately be reached for a comment. "We're excited to welcome some top AI coding talent from Windsurf's team to Google DeepMind to advance our work in agentic coding," the Google spokesperson said. As part of the deal, the search engine giant is entering a non-exclusive license for certain Windsurf technology, according to a source familiar with the matter. Google will not take a stake in Windsurf, the person said. Windsurf investors will receive liquidity as part of the deal, sources told Reuters. Google's surprise swoop mirrors a deal in August 2024 to hire key employees from chatbot startup Big Tech peers, including Microsoft, Amazon and Meta, have similarly taken to these so-called acquihire deals, which some have criticised as an attempt to evade regulatory scrutiny. Microsoft struck a $650 million deal with Inflection AI in March 2024, to use the AI startup's models and hire its staff, while Amazon hired AI firm Adept's co-founders and some of its team last June. Meta took a 49% stake in Scale AI in June in the biggest test yet of this increasing form of business partnerships. Unlike acquisitions that would give the buyer a controlling stake, these deals do not require a review by U.S. antitrust regulators. However, they could probe the deal if they believe it was structured to avoid those requirements or harm competition. Many of the deals have since become the subject of regulatory probes. The development comes as tech giants, including Alphabet and Meta, aggressively chase high-profile acquisitions and offer multi-million-dollar pay packages to attract top talent in the race to lead the next wave of AI. Windsurf's head of business, Jeff Wang, has been appointed its interim CEO, and Graham Moreno, vice president of global sales, will be president, effective immediately. The majority of Windsurf's roughly 250 employees will remain with the company, which has announced plans to prioritize innovation for its enterprise clients.

Tesla shareholders may get opportunity to invest in Elon Musk's AI venture xAI
In a significant move that could further blur the lines between Elon Musk's business empires, the billionaire has hinted that Tesla shareholders may soon be allowed to invest in his artificial intelligence start-up xAI, AFP reports. The decision, however, will be subject to a shareholder vote, Musk confirmed on his social media platform X. Responding to a user suggesting Tesla should invest in xAI, Musk said, "It's not up to me... We will have a shareholder vote on the matter." He further added, 'If it was up to me, Tesla would have invested in xAI long ago.' SpaceX Set to Back xAI with $2 Billion Investment According to The Wall Street Journal , another Musk-led company, SpaceX, will invest $2 billion in xAI as part of a larger $5 billion capital raise. Commenting on the report, Musk said the move 'would be great' but clarified that it too would require board and shareholder approval. Musk has previously highlighted potential synergies between xAI and his other companies, Tesla and SpaceX, particularly in advancing generative AI capabilities. xAI Aims for Sky-High Valuation Launched in July 2023, xAI is Musk's ambitious attempt to catch up with AI industry leaders like OpenAI (creator of ChatGPT), Anthropic (Claude), and Google's Gemini. According to The Financial Times , Musk is targeting a valuation between $170 billion and $200 billion for xAI in its upcoming funding round. xAI is currently investing heavily in infrastructure, building a massive data centre in Memphis, Tennessee—touted by Musk as the 'most powerful AI training system in the world.' The company has also acquired additional land for future expansions. High Costs, Early Controversies Despite its promise, xAI is reportedly burning through over $1 billion a month as it scales up operations, according to Bloomberg . The company is yet to generate significant revenue, and its flagship product—Grok, a generative AI assistant—has already faced controversies. Following a recent update on July 7, Grok was found issuing responses that praised Adolf Hitler and made offensive claims targeting individuals with Jewish surnames. xAI issued an apology and said it had corrected the instruction set responsible for the incidents. As Musk seeks to integrate xAI more closely with his larger tech ecosystem, the coming months will be crucial in determining whether Tesla shareholders embrace the opportunity—or raise concerns about further entangling Musk's multiple ventures.
