OpenAI Launches Cybersecurity Model GPT-5.5-Cyber in Europe!

OpenAI is rolling out its GPT-5.5-Cyber model in Europe, targeting vetted cybersecurity teams and institutions under the EU Cyber Action Plan. This model offers enhanced security capabilities but is not significantly more powerful than previous versions. With access governed by a Trusted Access framework, European organizations can now identify and validate software flaws more effectively. The move aims to establish a competitive edge against Anthropic's recently launched Mythos model.
