Finance leaders warn over Mythos as UK banks prepare to use powerful Anthropic AI tool

Release of new Claude model, so far limited to US firms, will expand to British institutions in coming days

British banks will be given access in the next week to a powerful AI tool that was deemed too dangerous to be released to the public, as a series of senior finance figures warned over its impact.

Anthropic, which has so far limited the release of the new model to a small clutch of primarily US businesses, including Amazon, Apple and Microsoft, said it would expand that to UK financial institutions in the coming days.
