Itaú rolls out generative AI for all customers and staff

Itaú, Brazil’s largest private bank, is launching generative AI tools across its full customer base and workforce. The bank announced two main products: ia.i, a conversational interface for customers and employees, and IARA, a governance platform to manage AI deployment. Itaú says this is part of its AI First strategy and will apply to both internal operations and public-facing services.

Why it matters

Brazil’s banking sector is one of the most tightly regulated in the world. Itaú’s move to deploy generative AI at this scale signals that large incumbents are shifting AI from back-office support to direct customer interaction. This puts pressure on smaller banks and fintechs to match the speed and automation that customers will now expect, even in markets where compliance requirements have slowed technology adoption in the past.

IARA, the governance platform, is Itaú’s answer to regulatory and risk concerns. OpenAI says IARA will help Itaú stay within regulatory guidelines, a key requirement for any bank using AI for customer-facing roles. Other countries have already started demanding documentation and controls for agentic AI systems, as seen in Hong Kong’s recent guidance. Itaú’s approach could set a new standard for Latin American banks.

How Itaú is deploying generative AI

OpenAI describes ia.i as a conversational interface that lets customers and employees interact with Itaú’s services using natural language. Customers can ask questions, get account information, and access support without waiting for a human agent. Employees can use the same system to automate routine tasks, which could reduce errors and free up time for more complex work.

IARA, the governance platform, is designed to manage AI models, track their use, and ensure compliance with Brazilian financial regulations. According to OpenAI, IARA provides oversight and governance, which is necessary as banks face scrutiny over automated decision-making and data privacy.

Itaú’s AI First strategy is a commitment to making generative AI a permanent part of its core systems. This is a departure from the industry’s usual slow, risk-averse approach to new technology. Itaú is betting that gains in efficiency and customer satisfaction will justify the investment and the risks of being early to scale.

What this means if you run a business

Itaú’s launch is a signal to business owners in regulated sectors. Large incumbents are now able to deploy AI-driven customer interfaces at scale, even under strict compliance requirements. Customers will expect faster, automated service, and regulators will expect clear documentation and control over AI systems.

If you operate in a regulated industry, Itaú’s use of a governance platform like IARA shows that technical implementation is not enough. You will need to demonstrate how your AI systems make decisions, how you audit them, and how you protect sensitive data. This can add cost and complexity, but it is becoming a baseline expectation for trust and contracts.

For smaller firms, the challenge is keeping up with new standards for service speed and transparency set by larger competitors using AI at scale. Itaú’s rollout could push other sectors to adopt similar governance and conversational AI tools, as both regulators and customers adjust their expectations. As seen in other recent AI vendor shifts, cost and control are now central to AI strategy, not just technical performance.
