According to a Bloomberg report, European Commission officials traveled to San Francisco on May 28 for talks with Anthropic, seeking more information about the capabilities of the Mythos model and pushing for its availability within the EU. Sources indicate that the discussions are still in an information-gathering phaseais and no final arrangements have been made. Launched in April this year, Mythos can automatically discover and exploit software zero-day vulnerabilities. Anthropic currently only makes it available to a select few US partners, leaving European financial institutions and critical infrastructure operators without access.
The talks are the latest step in the EU’s ongoing pressure campaign. In early May, EU Economy Commissioner Valdis Dombrovskis confirmed that the EU is in contact with Anthropic; in late May, Spain’s economic minister warned that negotiations have seen “limited progress.” Meanwhile, OpenAI has proactively committed to granting the European Commission access to its cybersecurity model GPT-5.5-Cyber. European Commission spokesperson Thomas Regnier also stated that once the AI Office’s enforcement powers come into effect in August this year, it will, if necessary, “ensure access” to Mythos. Anthropic simultaneously announced that the Mythos-class model is expected to be made available to all customers “in the coming weeks.”
