Grok 4.5 Is Live Worldwide, Except in the EU, Because of the AI Act
xAI's Grok 4.5 went live worldwide on July 8, 2026, but remains blocked across the European Union's 27 countries because the AI Act classifies the model as a systemic risk system. xAI promises access later in July, but with no confirmed date.
A Global Launch, With One Exception
xAI launched Grok 4.5 worldwide on July 8, 2026, available through Grok Build, the Cursor editor and the company's API console, according to TechCrunch. Elon Musk described the model as roughly comparable to Claude Opus 4.7, but much faster. More than two weeks after launch, though, the model remains unavailable across all 27 European Union countries.
The Reason Is Regulatory, Not Commercial
According to Cybernews and TrendingTopics.eu, the block stems from mandatory compliance requirements under the EU's AI Act for high capability AI systems, not a commercial decision by xAI. The AI Act classifies Grok 4.5 as a general purpose AI model with systemic risk, a category applied to models trained above a threshold of 10 to the 25th power floating point operations, which imposes additional risk assessment, technical documentation and transparency obligations before commercial release in the European bloc.
No Firm Arrival Date
xAI says EU access is expected later this July 2026, but has not given an exact date, according to the company's own developer guide. European users have voiced frustration on social media at seeing the model available everywhere else while they remain without official access, with some turning to VPNs to get around the block, a workaround that does not solve API access for companies bound by regulatory compliance.
Aggressive Pricing, Whenever It Arrives
Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, according to ExplainX, competitive pricing against other frontier models on the market. Once, and if, EU access opens within the promised window, the model should join the list of high performance, competitively priced options available to European companies, but for now that price comparison remains purely theoretical for anyone operating inside the bloc.
Why It Matters for Choosing a Model in Brazil
Brazil is not under the EU's AI Act, so Grok 4.5 has already been available here since the global launch. Even so, the episode is a warning for Brazilian agencies and companies serving European clients or planning to expand operations into Europe: AI model availability is not globally uniform, and architecture decisions that depend on a single vendor can run into regulatory barriers completely outside the technical control of the team building the product.
What's Clear
The Grok 4.5 case shows that regulatory fragmentation in AI is already a practical reality, not just a theoretical debate. While the AI Act raises entry barriers for systemic risk models in Europe, other jurisdictions, Brazil included, remain without an equivalent gate. For anyone building a product on top of third party models, the lesson is simple: never lock a product's architecture to a single AI vendor without accounting for the fact that the regulatory availability map changes from country to country, and can shift overnight.
