Will Chase Bank send a notice to customers about updates to its security protocols, referencing the threat of social engineering attacks that can be attributed to LLMs, before 2024?

Google Brain introduced the Transformer model in 2017 and advanced it further in 2018, which have become the basis of Large Language Models (LLMs). There is no formal definition for LLMs, though one article describes them as follows:

Typically, a large language model contains more than 100 billion parameters and is trained using advanced algorithms on a large corpus.

With the release of ChatGPT there has been speculation about the impact these increasingly capable LLMs will have on society.

One potential impact could be the use of LLMs to impersonate customers and account owners in the finance industry, such as by evading bank security protocols via chat support.

According to Wikipedia the bank JPMorgan Chase is the largest in the US by total assets and market capitalization. JPMorgan Chase is the parent company to its consumer and commercial banking subsidiary Chase Bank.
