Elon Musk’s AI chatbot Grok suffered major disruptions on Friday, with users reporting they couldn’t access the service, get replies, or sign in. DownDetector data showed most complaints came from the mobile app, while some users said the website wasn’t working properly. A smaller share reported login-specific problems. The spike peaked near 6:30 am IST at roughly 800 reports, and social media filled with screenshots of Grok failing to answer questions. xAI had not issued an official statement.
xAI’s Colossus 2 data center in Mississippi is facing legal scrutiny over its use of so-called “mobile” gas turbines as power plants. According to reporting, the facility is operating close to 50 turbines, raising questions about whether the company is complying with oversight and permitting rules. The lawsuit targets how the equipment is classified and deployed.

US officials removed details from a government website about an agreement with Microsoft, Google, and xAI. The arrangement reportedly let government scientists test new AI models for security flaws before they were released publicly. The deletion comes as national security concerns over advanced AI intensify, but officials have not clarified why the information was taken down.
Elon Musk says xAI will be dissolved as a standalone company and absorbed into SpaceX’s expanding AI operation, rebranded as “SpaceXAI.” The shift could alter the future of Grok and Musk’s broader AI strategy just as SpaceX deepens its partnership with Anthropic, giving Claude access to SpaceX’s Colossus supercomputer.
Anthropic says its compute partnership with xAI is already paying off for Claude subscribers, with higher rate limits rolling out immediately. The move follows related collaboration momentum, including Anthropic’s partnership with SpaceX, and signals faster scaling of Claude’s usage capacity. For users, it means fewer slowdowns and more reliable access as demand rises.
Anthropic is reportedly teaming up with xAI to supply additional computing capacity for Claude Pro and Claude Max subscribers. The move comes as Anthropic has faced service strain and xAI has dealt with hiccups in its recent model releases. If the partnership scales smoothly, users could see improved responsiveness and reduced congestion during peak demand.

Microsoft, Google, and xAI are partnering with the US government to provide early access to newly developed AI models. The Center for AI Standards and Innovation will evaluate the systems to assess national security risks before they’re released to the public. The effort is aimed at measuring advanced AI capabilities while identifying potential harms ahead of time.
Tesla earned over $500 million last year from Elon Musk’s other businesses. xAI contributed roughly $430 million, while SpaceX added about $143 million. The reported revenue links Tesla to services tied to AI chatbots and energy storage, with additional xAI-related revenue showing up for Tesla earlier this year.
xAI has released Grok 4.3, pairing a major pricing cut with a new “always-on” reasoning design and a 1 million-token context window. The model is aimed at agentic tasks, with built-in web search, code execution, and file retrieval tools. xAI also launched custom voice cloning from 120-second samples, priced for enterprise use—available with geographic limits and enterprise-gated API access.
Elon Musk testified that xAI trained Grok using OpenAI models, drawing attention to “distillation,” the method used to transfer capabilities into smaller systems. The claim intensifies scrutiny of how frontier AI labs protect their models while challengers argue they can learn from outputs. Legal and technical debates over copying, licensing, and competitive fairness are likely to intensify.

Elon Musk’s $150 billion lawsuit against OpenAI is no longer just a legal fight. In a sharp X attack, Musk called Sam Altman “Scam Altman,” while the trial in California centers on claims that OpenAI abandoned its non-profit mission after shifting to a capped-profit model and partnering with Microsoft. OpenAI says the structure was necessary—and rivalry with xAI drives the case.
The US Justice Department has intervened in xAI’s challenge to a Colorado tech law, arguing it violates the Fourteenth Amendment’s equal protection guarantee. In court papers, the department says the law forces companies to prevent unintended discriminatory effects while still permitting certain discrimination intended to advance diversity goals—an approach it says is unconstitutional.
xAI’s legal chief, Keele, has resigned, saying the role was a “dream” and the team exceptional. In posts on X and LinkedIn, she praised working with Elon on the technology but said work-life balance concerns drove the decision, despite admiration for the company’s vision, commitment, and daily smart execution.
Elon Musk claims xAI’s next Grok model could correct inaccuracies found in Wikipedia by using vast amounts of synthetic data to refine answers and add missing context. Amid rising AI competition, Musk hinted the system might even move toward a “Grokipedia,” raising questions about who controls updates to widely used public knowledge.
