American International Group (AIG) has made significant strides in its use of generative AI, leading to substantial improvements in underwriting capacity, operating costs, and portfolio integration. The company’s recent Investor Day disclosures have highlighted the tangible benefits of its AI deployment, including enhanced submission processing capacity and streamlined workflows.
AIG’s CEO, Peter Zaffino, initially described the company’s early projections as ‘aspirational,’ but later noted that ‘we see the abilities are much greater’ in a fourth-quarter earnings call, suggesting that the company has seen positive internal results. Zaffino emphasized that ‘we’re seeing a massive change in our ability to process a submission flow way… without additional human capital resources.’
The economic implications of AIG’s claims that generative AI has increased submission processing capacity are substantial. The company reported that in 2025, it ‘made progress embedding generative AI in our core underwriting and claims processes, and expanding it.’ AIG’s internal tool, AIG Assist, is implemented in most commercial lines of businesses, with Lexington Insurance, AIG’s excess and surplus unit, targeting 500,000 submissions by 2030.
AIG leverages generative models to extract and summarize incoming data and has developed an orchestration layer in its technology stack ‘to coordinate AI agents to drive better decision-making and reduce costs in the organization.’ The company relies on its ability to manage incoming data ‘at a fraction of the time’ and to orchestrate agents so they can ‘scale and be able to analyze that information that’s not biased in any way; that’s through the entire workflow.’
The launch of Lloyd’s Syndicate 2479, in partnership with Amwins and Blackstone, extended the company’s use of generative AI, demonstrating its potential for application in specific transactions. As AIG continues to refine its AI deployment, the industry can expect to see significant advancements in underwriting capacity, operating efficiency, and portfolio integration.
