A billionaire AI boss sued a beloved California firefighter after claiming he damaged his $40 million Malibu beach mansion while installing a system designed to protect the home from wildfires.

Daniel Nadler, 42, the CEO of OpenEvidence— a Google-backed artificial intelligence company described as “ChatGPT” for doctors — filed the lawsuit Tuesday morning before it was mysteriously withdrawn hours later.

The lawsuit, which The Post understands will be refiled, accused firefighter Robert Milstein of smashing his “heavy vehicle” into the exterior wall of the sprawling oceanfront estate, which Nadler claims slashed the home’s value by “millions.”

The architect-designed beachfront home features rare rammed-earth walls meant to resemble weathered coastal stone.

Milstein, who runsSoCal Fire Supply, had been setting up a fireproofing system at the mansion on October 9, 2025.

The veteran firefighter is part of the LA County Fire Community Brigade, which assists the LAFD during emergencies, and has spent two decades building a reputation as a firefighting hero in Santa Monica.

He helped save the famed Calamigos Ranch duringthe devastating 2018 Woolsey Fireand is credited by locals with defending Big Rockduring January’s Palisades Fire, helping evacuate hundreds of residents while saving millions of dollars in property.

The lawsuit alleges Milstein damaged “multiple rammed earth panels, compromising the panels’ exterior façade.”

Nadler claims the wall’s rare composition means “partial repairs will only further the damage and create a patchwork-like blight to a wall that was intended to appear as one continuous, weathered stone.”

But Milstein insists the billionaire is overstating the damage.
