OpenAI Extends EU Access to Advanced GPT-5.5-Cyber AI Model as Anthropic Maintains Cautious Stance on Mythos - Tekedia

OpenAI has given EU regulators and vetted partners early preview access to its cybersecurity-focused GPT-5.5-Cyber model.

The company also launched an EU cyber action plan to coordinate technical engagement and reduce regulatory concerns.

Anthropic has not yet offered comparable early access to its Mythos system, highlighting a more cautious approach.

The European Commission welcomed OpenAI’s move and said more technical talks with the EU AI Office are planned.

The step could influence how Europe assesses frontier AI in cybersecurity and whether early transparency leads to lighter scrutiny.
