OpenAI details layered protections in US defense department pact

Feb 28 (Reuters) – OpenAI said on Saturday that the agreement it struck a day ago with the Pentagon to deploy technology on the U.S. defense department’s classified network includes ​additional safeguards to protect its use cases.

U.S. President Donald Trump ‌on Friday directed the government to stop working with Anthropic, and the Pentagon said it would declare the startup a supply-chain risk, dealing a major blow to the artificial intelligence lab after a showdown about technology guardrails. Anthropic said ‌it ​would challenge any risk designation in court.

Soon ⁠after, rival OpenAI, which is ⁠backed by Microsoft, Amazon, SoftBank and others, announced its own deal late on Friday.

“We think our agreement has more guardrails than any previous agreement for classified AI deployments, including Anthropic’s,” OpenAI said ​on Saturday.

The AI firm said that the contract with the Department of Defense, which the Trump administration has renamed the Department ⁠of War, enforces three red lines: OpenAI ⁠technology cannot be used for mass domestic surveillance, ​to direct autonomous weapons systems, or for any high-stakes automated decisions.

“In our ​agreement, we protect our red lines through a more expansive, ‌multi-layered approach. We retain full discretion over our safety stack, we deploy via cloud, cleared OpenAI personnel are in the loop, and we have strong contractual protections,” OpenAI said.

The Pentagon signed agreements worth up ⁠to $200 million each with major AI labs in the past year, including Anthropic, OpenAI and Google. The Pentagon is seeking to preserve all flexibility ⁠in defense and ‌not be limited by warnings from the technology’s ⁠creators against powering weapons with unreliable AI.

OpenAI cautioned that ​any ‌breach of its contract by the U.S. government ​could trigger ⁠a termination, though it added, “We don’t expect that to happen.”

The company also said rival Anthropic should not be labeled a “supply-chain risk,” noting, “We have made our position on this clear to the government.”
