March 17 (Reuters) - OpenAI has ‌signed a ​new ​deal to sell access to its AI models to U.S. defense and government agencies through Amazon's cloud unit ‌for classified and unclassified work, the ChatGPT maker said ⁠on Tuesday.

The contract enables OpenAI to support the Pentagon under a deal it ‌secured late last month, after ‌the agency dropped its previous AI provider, Anthropic.

Anthropic, which won a Pentagon contract worth up to $200 million in July 2025, ​had been a key U.S. defense AI supplier, working with Palantir and Amazon Web Services (AWS) to deploy its Claude models ⁠in classified military and intelligence systems.

But its relationship with the Pentagon collapsed in February after ​Anthropic refused to allow unrestricted military use of its AI, particularly for domestic surveillance and autonomous weapons. ​Following which, the Pentagon labeled it ‌a "supply chain risk" and effectively cut it off from government work.

OpenAI, which had previously focused on unclassified ⁠government use, has now secured a Pentagon contract to provide its models for classified operations.

Its partnership with AWS builds on this latest shift, ⁠reflecting how access to government and defense contracts, especially via cloud providers already ​embedded in federal systems, is becoming a key battleground.

Securing government contracts could also help the ChatGPT maker attract large corporate clients, which often see high-stakes ‌public sector work as a strong signal of trust and reliability.

Following OpenAI's transition to a for-profit ‌structure last fall, the company updated its agreement with Microsoft to ⁠allow partnerships with rival cloud ‌providers in selling AI ​to national security customers, including the Pentagon.
