Wall Street banks are testing Anthropic's Mythos model internally.

Wall Street banks are beginning to internally test Anthropic PBC's Mythos model, after Trump administration officials encouraged them to use the model to detect system vulnerabilities. According to sources familiar with the matter, although JPMorgan Chase is the only bank named to participate in testing the Mythos model, other large financial institutions have either already received or are expected to receive permission to use the model in the coming days. These sources indicate that Goldman Sachs, Citigroup, Bank of America, and Morgan Stanley are all internally testing this technology. These institutions either declined to comment or have not yet responded.
