American Express (Amex) is planning to use artificial intelligence (AI) for transaction validation, credit approval, customer sentiment analysis, and financial predictions.

However, they have no plans to develop their own large language model (LLM) and instead plan to utilize LLMs through partnerships.

Amex has collaborated with Microsoft in the past for cloud-based AI technologies, but the exact partners for their AI services are undisclosed.

By partnering with established technology companies, Amex can leverage state-of-the-art AI technologies without investing in building their own LLM from scratch.
