"Taking the mortgage underwriting process, which so many of us have experienced personally, from 21 days to as little as 47 seconds and enabling it via ChatGPT is a huge unlock for everyone," said Giancarlo Lionetti, OpenAI's chief commercial officer

. The partnership represents a significant shift in how the $1 trillion annual U.S. home-loan market operates, targeting inefficiencies that have plagued the mortgage industry for decades.

How the Tinman AI Platform Reshapes Mortgage Processing for Loan Officers

The AI mortgage engine allows loan officers at banks, mortgage brokers, and fintech firms to underwrite mortgages and generate qualification letters with a median time of 2 minutes and 24 seconds. Loan officer Tony Song said the platform will allow him to "serve 10x more customers daily compared to what was possible with the traditional mortgage underwriting process"

OpenAI's models, fed with Better.com's mortgage data, save time by simultaneously running parallel workflows on dozens of checkpoints, including appraisals, title reports, income, credit reports and other metrics

. "It's not a simple tool call. It's a multiple tool call with a super long, extended logic tree and a very large context window," explained Better.com CEO Vishal Garg

Cutting Costs and Challenging Industry Giants

The Better.com and OpenAI partnership takes direct aim at what Garg calls a "tax" charged by large mortgage aggregators. "Rocket, UWM, Pennymac, a bunch of guys that are large public companies, make their money by effectively charging a tax of one and half percent to underwrite mortgages. ... That's $20 billion that's paid by the American public in a typical year," Garg said

Better.com has already cut the cost to originate a loan from the industry standard of $9,200 to roughly $3,000, passing savings to consumers

2

. "The mortgage industry is riddled with inefficiencies that hurt consumers and the loan officers who serve them," said Leah Price, General Manager of Tinman AI Platform. "Big mortgage aggregators charge what is essentially a 1% to 2% tax on each loan just to underwrite a mortgage. That ends now"

Massive Data Foundation Powers AI Underwriting

The Tinman AI Platform is built on more than $110 billion in funded loans, over 12 million recorded customer calls, and over 5 billion pages of documentation. The system includes underwriting criteria and pricing parameters covering over 80% of the U.S. mortgage market, with capabilities for over 45 institutional mortgage investors including Fannie Mae, Freddie Mac, FHA, and banks such as J.P. Morgan Chase, Truist, Citizens Bank, US Bank, Huntington Bank, and Fifth Third.

By embedding Tinman inside ChatGPT—a platform 100 million Americans already use—Better.com is making its technology available to the entire mortgage industry for the first time

2

. Lending teams can simply log into their ChatGPT Enterprise account, download the app, and connect their guidelines, pricing, and customer relationship management systems to process and underwrite loans nearly instantly.

Strategic Pivot to Mortgage-as-a-Service

The new app represents Better.com's strategic pivot from being primarily a lender to consumers to also becoming a "mortgage-as-a-service" tech platform for other mortgage players

1

. This shift positions the company to capture value across the broader mortgage industry rather than competing solely as a direct lender. The launch expands Better's collaboration with OpenAI, which includes enterprise-wide deployment of ChatGPT across its 1,400 employees and use of OpenAI's multimodal models for Betsy, Better's AI loan agent.

For now, the tool is available to loan officers and financial institutions—not consumers directly—though that may change down the line

2

. Garg told reporters, "We're just getting started," suggesting further innovations may be on the horizon to reduce mortgage approval times even further
