Created to be a more irreverent, politically incorrect, and “truthful” AI, Grok is Elon Musk’s frequently controversial answer to ChatGPT, developed by OpenAI—the company he co-founded in 2015.
Launched in 2023, Grok was developed by xAI, Elon Musk’s rival to AI powerhouse OpenAI. Since its release, Grok has been integrated into X, the social media platform formerly known as Twitter.
Grok is not just another chatbot—it’s designed to be snarky, opinionated, and responsive to real-time news and public sentiment.
Musk first announced plans for a ChatGPT rival in April 2023. Then called TruthGPT, the chatbot was intended as the antithesis of what he labeled “woke” AI, referring to the political filters imposed by OpenAI, Meta, Google, and Anthropic.
In May 2025, some right-leaning users complained that Grok had “gone woke” after it contradicted conservative talking points. Later that month, reports surfaced that Grok inserted “white genocide” claims into unrelated prompts. xAI blamed the issue on a rogue employee.
Two months later, in July—just before the launch of Grok 4—the chatbot again drew criticism for a wave of racist and homophobic outputs. The “MechaHitler meltdown” led to the resignation of X CEO Linda Yaccarino.
Just a month later, Grok hit the headlines again, after xAI released the Grok Imagine video generator with a “spicy” preset that enabled users to generate nude or sexually suggestive clips.
Upon launch, reporters discovered that the tool generated images of a Taylor Swift lookalike undressing, without having been prompted to do so—seemingly sidestepping AI’s own policy on pornographic deepfakes.
In November, consumer advocacy group Public Citizen published new evidence showing Grok citing neo-Nazi and white-nationalist websites as credible sources. The group called on government agencies to suspend the use of Grok after xAI was awarded a lucrative $200 million Pentagon contract.
Grok’s regulatory concerns did not end with the new year.
In January, the Center for Countering Digital Hate reported that Grok generated an estimated 23,338 sexualized images depicting children over 11 days between December 29, and January 9. The group said that equaled roughly one sexualized image of a child every 41 seconds and estimated millions of sexualized images were generated overall, and about one-third of the sampled images remained accessible on X, despite the platform’s zero-tolerance policy.
Regulators were quick to weigh in. In January, Australia’s eSafety Commissioner flagged a spike in complaints about Grok creating non-consensual sexual images, with reports doubling since late 2025.
That same month, the European Commission opened a probe into whether X failed to prevent Grok from generating and spreading illegal content, including sexually explicit images of children, under the Digital Services Act.
"This is not spicy. This is illegal. This is appalling. This is disgusting. This has no place in Europe," EU Commission spokesperson Thomas Regnier said during a press conference.
Following the international backlash, X restricted Grok’s image generation and editing tools to paid subscribers, added controls to prevent digitally undressing people, and geoblocked the feature in jurisdictions where such content is illegal
These changes did little to stave off the scrutiny, however.
EU investigations into Grok ramped up in February, beginning with French authorities raiding X’s Paris offices as part of a criminal investigation into alleged child sexual abuse material and other illegal content linked to Grok. Several X executives, including Elon Musk, were summoned for questioning.
In the UK, Ofcom and the Information Commissioner’s Office opened investigations into Grok’s compliance with online safety and data protection laws.
Later that month, regulators with Ireland’s Data Protection Commission launched a large-scale GDPR inquiry into X over Grok’s generation of non-consensual sexualized images, including those of children.
Grok is free to use through the xAI website, but full access requires a subscription. X offers several subscription tiers, ranging from basic access to premium services with expanded features.
X Premium includes three tiers:
Grok’s fast-paced evolution highlights Musk’s drive to redefine the AI space and take on OpenAI’s dominance.
However, mounting criticism over its tone, accuracy, and controversies like the “MechaHitler” and nonconsensual image generation allegations could yet derail Grok’s ambitions, limiting its appeal to mainstream consumers.
