UK banks get access to OpenAI GPT-5.5 as Anthropic expands
UK banks have been offered access to OpenAI’s GPT-5.5 while being left out of Anthropic’s Glasswing expansion, according to the report. The move adds another option for financial firms as major AI vendors compete for enterprise customers.
UK banks have been offered access to OpenAI’s GPT-5.5, even as they remain excluded from Anthropic’s Glasswing expansion, according to the source report. The development shows how major AI vendors are continuing to court financial institutions with new models and access programs.
The report says 150 new organizations were inducted into Anthropic’s cyber-focused program, described as a kind of “cyber’s Soho House,” but UK banks were not included in that expansion. At the same time, those banks were offered access to OpenAI’s GPT-5.5, giving them a separate route into the latest OpenAI model.

This matters because banks handle sensitive financial data and are heavily regulated, so the AI tools they use can affect privacy, compliance, and security. GPT-5.5 is a newer OpenAI model, while Anthropic’s Glasswing expansion appears to be a program for security-focused organizations. The story shows how AI vendors are trying to get into trusted industries by offering early access and special programs.
🦞 OpenClaw angle
If you build AI tools for regulated customers, separate model evaluation from vendor hype. Test access programs against your own controls for logging, data retention, and prompt handling before you let agents touch real customer data. If one vendor excludes your region or sector, keep a second model path ready so your automation stack is not tied to a single supplier.
The source does not spell out which banks received the offer or whether the access is limited, but it places the move in the broader context of competition between OpenAI and Anthropic for enterprise and security-related customers. Financial services firms are attractive targets for AI vendors because they tend to have large budgets, strict compliance needs, and high demand for automation.
Anthropic’s Glasswing expansion appears to be tied to cyber and security use cases, based on the report’s framing. The program’s expansion to 150 new organizations suggests Anthropic is widening access, though the source specifically notes that UK banks were excluded from this round.
OpenAI’s GPT-5.5 is mentioned as the model being offered to UK banks, but the article does not provide technical details about the model or the terms of access. It also does not say whether the banks were being invited to test, deploy, or evaluate the model in production.
The reporting does make one thing clear: banks are being approached as valuable customers in the race to place AI inside regulated industries. For both OpenAI and Anthropic, the financial sector is a major proving ground for model adoption, vendor relationships, and security scrutiny.
The source also links the story to a larger pattern of AI suppliers competing for footholds in cyber and enterprise markets. Anthropic’s expanded program and OpenAI’s bank access offer are presented as parallel moves, with different companies using different routes to win influence inside sensitive organizations.
