OpenAI is granting dozens of major European companies access to the latest versions of its AI tools, targeting sectors including finance, telecommunications, energy, and public services. Partners announced include Deutsche Telekom, Spanish bank BBVA, Telefónica, and German investment platform Scalable Capital, with OpenAI framing the move as a way to help organisations detect vulnerabilities and respond rapidly to digital threats. The expansion comes as rival AI firm Anthropic recently launched a new system called Mythos that has raised concerns about making it easier to circumvent the security of institutions such as banks.
