The US Department of Homeland Security (DHS) published its 2025 AI use case inventory, showing law enforcement operations as the agency’s most common application of AI. Of 238 AI use cases listed across DHS, 86 were categorized as law enforcement, with Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE) accounting for a majority of DHS’s reported AI deployments (CBP 83, ICE 51). DHS also reported that 35 law-enforcement AI use cases were designated “high impact” under Office of Management and Budget (OMB) criteria, meaning outputs can materially affect rights or safety; examples cited include anomaly detection, smartphone forensics triage, open-source/social media analysis, and biometrics-driven capabilities such as facial recognition.
Within the inventory, ICE disclosed an “AI Enhanced ICE Tip Processing” capability used to sort, translate, and summarize public tip submissions to help investigators prioritize urgent cases and reduce manual review. Reporting indicates the service uses Palantir generative AI tooling to produce a “BLUF” (bottom-line-up-front) summary using one or more commercially available large language models; DHS stated the models were trained on public-domain data by providers and were not additionally trained on agency data, though they do process tip submissions during operation. The inventory lists the tool as becoming operational on May 2, 2025, and notes it was not present in the prior year’s inventory.

DHS published its 2025 AI use case inventory, showing 238 deployed AI use cases, with law enforcement as the largest category. The inventory also showed ICE’s AI use cases nearly doubled from 2024 and documented the new ICE tip-processing system.
DHS’s 2025 AI Use Case Inventory lists ICE’s 'AI Enhanced ICE Tip Processing' capability as operational as of May 2, 2025. The Palantir-supported system uses generative AI to sort, translate, summarize, and prioritize public tips for investigators.
A DHS Office of Inspector General report said the department was delinquent in mandatory AI reporting and had initially omitted 66 use cases, including ICE’s facial recognition system. The report criticized DHS’s AI governance practices.
DHS expanded its AI adoption by launching an internal generative AI chatbot. The rollout was cited as part of the department’s broader increase in AI use across components.
