How Itaú is building generative AI for its entire customer base
What happened
Itaú is deploying a conversational AI layer called ia.i, powered by OpenAI models, to serve its 70 million customers across banking services such as checking accounts, credit, cards, insurance, and more. The system uses a Customer DNA layer to provide personalized context and is governed by IARA, a platform that controls model access and ensures compliance. The solution supports multimodal interactions—text, voice, image—and connects users to human support when needed. Early rollout reached about 300,000 customers, with the bank learning how the tool improves daily financial decisions.
Why it matters
By making banking interactions simpler and more personalized, the AI could help ordinary users manage finances more effectively. It also shows how large banks can integrate advanced AI while maintaining governance and privacy.
Reality check
An automated, sceptical read of the sourceIncremental. The approach uses existing OpenAI models and standard governance practices, extending them to a large banking context rather than introducing a fundamentally new technology.
Is this a big deal?
