Spain Demands Early Access to Anthropic's Mythos AI Model 2026

Spain is pushing for early access to Anthropic's Claude Mythos Preview, a powerful AI model that has raised alarms across Europe. The Spanish government wants to evaluate the model's ability to find vulnerabilities in financial systems before it becomes widely available.

Carlos Cuerpo, Spain's Vice President and Minister of Economy, made it clear that the European Union needs "early access" to Mythos to assess risks. He stated that "Europe cannot be a second-class region," but for now, at least for the most powerful AI startups, it is.

Why Spain Wants Early Access to Mythos

The initial alarm came from the financial sector, but the Spanish government warns that Mythos's ability to find "backdoors" affects nearly all economic sectors. Critical infrastructure and essential elements for any modern country are at risk.

Anthropic itself has acknowledged these fears. The company decided not to release the model publicly to prevent it from falling into the wrong hands. This cautious approach has only heightened concerns among European officials.

The EU AI Act: A Double-Edged Sword

The EU AI Act was celebrated as the world's first major regulation of AI technology. However, it has become clear that it may be a shot in the foot for EU countries. Advanced AI models often cannot be used within EU borders because they might violate the regulation.

This regulatory hurdle puts European countries at a disadvantage. While the US and China race ahead with AI development, Europe risks being left behind. Spain's request for early access is a direct response to this growing gap.

What This Means for the Financial Sector

Banks and financial institutions are particularly vulnerable. Mythos's ability to identify backdoors could expose weaknesses in their systems. Without early access, European regulators cannot properly assess these risks.

The Spanish government argues that waiting for a public release is not an option. By then, the damage could already be done. Early access would allow regulators to understand the model's capabilities and prepare defenses.

Key Takeaways

• Spain is requesting early access to Anthropic's Claude Mythos Preview to assess financial vulnerabilities.
• The EU AI Act may be hindering European access to advanced AI models.
• Mythos's ability to find backdoors poses risks to critical infrastructure across all sectors.
• Anthropic has withheld public release due to safety concerns.
• Europe fears becoming a second-class region in AI development.

What to Watch Next

Spain's request is likely to spark debate among EU member states. If granted, it could set a precedent for other countries seeking early access to powerful AI models. If denied, it may accelerate calls to reform the EU AI Act. The background to this story is set out in US Government Restricts Anthropic's Mythos 5 AI Model Access.

Anthropic has not yet responded to Spain's request. The company faces pressure to balance safety concerns with demands for transparency.
