As Israel uses US-made AI models in war, tech can decide who lives and who is killed

Israel’s recent wars mark a leading instance in which commercial AI models made in the United States have been used in active warfare.

U.S. tech giants have quietly empowered Israel to track and kill many more alleged militants more quickly in Gaza and Lebanon through a sharp spike in artificial intelligence and computing services. But the number of civilians Israel killed has also soared, fuelling fears that these tools are contributing to the deaths of innocent people.

Militaries have for years hired private companies to build custom autonomous weapons. However, Israel's recent wars mark a leading instance in which commercial AI models made in the United States have been used in active warfare, despite concerns that they were not originally developed to help decide who lives and who dies.

The Israeli military uses AI to sift through vast troves of intelligence, intercepted communications and surveillance to find suspicious speech or behavior and learn the movements of its enemies. After a deadly surprise attack by Hamas militants on October 7, 2023, its use of Microsoft and OpenAI technology skyrocketed, an Associated Press investigation found. The investigation also revealed new details of how AI systems select targets and ways they can go wrong, including faulty data or flawed algorithms. It was based on internal documents, data and exclusive interviews with current and former Israeli officials and company employees.

“This is the first confirmation we have gotten that commercial AI models are directly being used in warfare,” said Heidy Khlaaf, chief AI scientist at the AI Now Institute and former senior safety engineer at OpenAI. “The implications are enormous for the role of tech in enabling this type of unethical and unlawful warfare going forward.”

As U.S. tech titans ascend to prominent roles under President Donald Trump, the AP’s findings raise questions about Silicon Valley’s role in the future of automated warfare. Microsoft expects its partnership with the Israeli military to grow, and what happens with Israel may help determine the use of these emerging technologies around the world.

The Israeli military’s usage of Microsoft and OpenAI artificial intelligence spiked last March to nearly 200 times higher than before the week leading up to the October 7 attack, the AP found in reviewing internal company information. The amount of data it stored on Microsoft servers doubled between that time and July 2024 to more than 13.6 petabytes — roughly 350 times the digital memory needed to store every book in the Library of Congress. Usage of Microsoft’s huge banks of computer servers by the military also rose by almost two-thirds in the first two months of the war alone.

Israel’s goal after the attack that killed about 1,200 people and took over 250 hostages was to eradicate Hamas, and its military has called AI a “game changer” in yielding targets more swiftly. Since the war started, more than 50,000 people have died in Gaza and Lebanon and nearly 70% of the buildings in Gaza have been devastated, according to health ministries in Gaza and Lebanon.
