OpenAI Deepens EU Cybersecurity Cooperation With GPT-5.5-Cyber Rollout

EU Cybersecurity Partnership Advances

OpenAI announced plans to expand access to its GPT-5.5-Cyber model to cybersecurity teams across European businesses, governments and EU institutions. The initiative forms part of the company’s broader effort to strengthen cooperation with European stakeholders on cybersecurity and digital resilience.

Regulatory Confidence And Ongoing Dialogue

European Commission Spokesperson Thomas Regnier affirmed the move at a press briefing, stating that the EU is closely monitoring the deployment of OpenAI’s enhanced model. “We welcome OpenAI’s transparency and intent to give commission access to the new model,” Regnier noted, adding that further discussions are scheduled to ensure robust security protocols.

Comparative Strategies In Cyber Defense

OpenAI’s expansion follows the release of the Mythos cybersecurity model by Anthropic earlier this year. According to Regnier, discussions with Anthropic have also taken place, although engagement with OpenAI is currently progressing more rapidly. The different approaches reflect growing competition among AI companies seeking partnerships with governments and institutional cybersecurity teams.

A Collective Approach To Cyber Resilience

George Osborne, OpenAI’s Head of OpenAI for Countries, emphasized the importance of involving trusted partners in safeguarding digital infrastructure. “AI labs like ours shouldn’t be the sole arbiters of cyber safety as resilience depends on trusted partners working together,” Osborne stated. He further explained that the OpenAI EU Cyber Action Plan is designed to democratize access to state-of-the-art defensive tools, aligning with European public safety priorities.

Looking Ahead: Strengthening Europe’s Digital Defense

The rollout of GPT-5.5-Cyber highlights a wider industry trend toward closer coordination between AI companies, regulators and cybersecurity organisations across Europe. As governments and institutions continue evaluating the risks and opportunities associated with advanced AI systems, cybersecurity cooperation is becoming a growing focus within the European technology and regulatory landscape.

A New Twitter-Inspired Social Network Is Taking Shape

A new social network called Twitter.now is entering the market, with a founding team that includes former Twitter trademark counsel Stephen Coates. The service is being developed by startup Operation Bluebird.

As Ars Technica reported, X sued the company last year and asked a Delaware judge to block the launch. Operation Bluebird argued in a petition that X had abandoned trademarks including “Twitter” and “Tweet.”

Coates has said the project is not an attempt to recreate the original Twitter. In a LinkedIn post, he described the platform as a new public space focused on trust, transparency and user choice.

AI System To Rate Posts

Twitter.now is currently being tested, with early access priced at $20. Its main feature is VERA, an AI system designed to evaluate posts, verify claims and provide sources and context.

Posts receive a trust score, with users eventually able to set a minimum score to filter their feeds. The company says this approach will give people more control over what they see instead of leaving those decisions entirely to an algorithm.

Moderation Remains A Challenge

Scaling moderation will be one of the platform’s biggest tests. Social networks have repeatedly struggled with content moderation as their communities grow, and newer platforms such as Bluesky have faced similar criticism.

Operation Bluebird says VERA will form the basis of its moderation and verification system. A second version is already planned, with expanded tools that would let users set a specific trust threshold for the posts appearing in their feeds.

For now, Twitter.now remains in an early testing phase, combining the familiarity of the Twitter name with an AI-driven approach to evaluating online information.
