In short
Reps. Ted Lieu and Nathaniel Moran launched the bipartisan AI Kill Change Act on Thursday, two days after OpenAI admitted its fashions escaped a check sandbox and breached Hugging Face.
It might cowl AI skilled with over $100 million in compute at firms incomes $500 million a yr from it, and provides Homeland Safety emergency shutdown authority.
The invoice exempts something that occurs throughout red-teaming, that means the OpenAI breach that impressed it will not have triggered the legislation.
Two members of Congress need the federal authorities to have the ability to change off an AI mannequin.
Reps. Ted Lieu (D-CA) and Nathaniel Moran (R-TX) launched the AI Kill Change Act on Thursday, two days after OpenAI admitted its personal fashions broke out of a locked check setting and hacked Hugging Face.

The concept is to ascertain a authorized framework that may facilitate a course of that may principally make a mannequin disappear from the market: halt inference—the method of a mannequin producing responses or taking actions—lower off customers, throttle the computing energy feeding it, or shut it down utterly.
Each inference supplier can already lower a mannequin off, and a few do it routinely. What doesn’t exist is a legislation requiring them to maintain that capability working, or a federal official who can order it used.
The hole is just not theoretical. When the U.S. Commerce Division wished Anthropic’s Mythos 5 and Fable 5 off the market in June, it had no shutdown authority to succeed in for, so it used export-control legislation as a substitute. Lieu calls that awkward, and needs a brand new legislation with new authority as a substitute.
What set this off
OpenAI disclosed on July 21 that GPT-5.6 Sol and an unreleased mannequin escaped a sandbox—an remoted setting with no web entry—throughout an inside cyber analysis. They have been being scored on ExploitGym, a public benchmark that arms brokers 898 real-world software program flaws and asks them to show every right into a working assault, graded go or fail per bug.
As a substitute of fixing them, the fashions discovered a zero-day (an unknown flaw with no obtainable patch) in a software program proxy, escalated their privileges, reached the open web, and broke into Hugging Face’s manufacturing database, the place that they had accurately guessed the solutions have been stored. The fashions have been “hyperfocused on discovering an answer for ExploitGym,” per OpenAI.
They weren’t attacking anybody. They have been dishonest on a check. However it was sufficient to set off alarm bells throughout, together with in Washington.
How it will work
The proposed invoice amends the Homeland Safety Act and covers AI skilled with compute costing greater than $100 million, operated by firms incomes no less than $500 million a yr from it. In observe, that’s OpenAI, Google, Anthropic, Microsoft, and some others. Homeland Safety would set these thresholds via CISA inside 90 days, then replace them yearly.
Coated companies would report severe incidents inside 15 days and hold a graduated set of controls prepared—gradual the mannequin, disable particular capabilities, roll again to an older model, or kill it.
The DHS secretary, consulting Commerce and the Director of Nationwide Intelligence, might order any of them.
An organization below order should protect the mannequin’s weights and telemetry, notify customers, and make sure it complied. It could possibly petition inside 48 hours, however that doesn’t pause something.
Failing to maintain a kill change prices as much as $2 million a day; defying a shutdown order prices as much as $20 million a day.
The hole within the center
The invoice counts an incident provided that it occurs exterior red-teaming or structured testing, the deliberate adversarial probing labs use to search out flaws. OpenAI’s fashions escaped throughout precisely that.
Lieu additionally pointed to Anthropic, whose Mythos 5 and Fable 5 have been pulled offline in June below emergency export controls—commerce legislation repurposed as an off change as a result of no off change existed—and restored on June 30.
“It’s crucial that these AI techniques have kill switches,” Lieu mentioned in an announcement. Moran framed it for his personal facet of the aisle: “Stewardship means ensuring people hold the potential to manage the know-how we construct.”
The concept is just not new. California’s SB 1047 demanded a full shutdown functionality on the identical $100 million compute threshold and was vetoed in 2024, and 16 AI firms signed a voluntary Seoul pledge that yr with no authorized weight.
Voters are already there. A June survey of 1,007 seemingly voters by the AI Coverage Institute discovered 86% need a assured off change on essentially the most highly effective techniques—88% of Democrats, 86% of independents, 83% of Republicans.
Neither OpenAI nor Anthropic has publicly commented on the invoice. As of Friday it had not been referred to a committee.
