U.S. Immigration and Customs Enforcement Deploys Palantir’s AI to Process Public Tips in Real Time

In a move that blends cutting-edge artificial intelligence with law enforcement operations, U.S. Immigration and Customs Enforcement (ICE) has begun using Palantir’s generative AI tools to process and summarize immigration enforcement tips submitted through its public tip line. The revelation comes from the Department of Homeland Security’s (DHS) newly released 2025 AI Use Case Inventory, which catalogs the agency’s growing reliance on AI across its operations.

According to the inventory, the “AI Enhanced ICE Tip Processing” service is designed to help ICE investigators “more quickly identify and action tips” for urgent cases. The system also translates submissions not made in English and produces a “BLUF”—a military acronym for “bottom line up front”—which serves as a high-level summary of each tip using at least one large language model (LLM).

DHS says the software is “being actively authorized” in support of ICE operations and helps reduce the “time-consuming manual effort required to review and categorize incoming tips.” The tool officially became operational on May 2, 2025, according to the inventory.

The inventory provides limited details about the specific large language models Palantir employs. However, it confirms that ICE uses “commercially available large language models” trained on public domain data by their providers. Notably, the inventory states, “There was no additional training using agency data on top of what is available in the models’ base set of capabilities. During operation, the AI models interact with tip submissions.”

This development marks a significant evolution in ICE’s tip-processing capabilities. While Palantir has been a major ICE contractor since 2011, providing analytical tools for investigative case management, the company’s work processing tips has remained largely unknown until now. The only previous public mention came in September 2025, when ICE made a $1.96 million payment to Palantir to modify its Investigative Case Management System (ICM) to include the “Tipline and Investigative Leads Suite.”

The AI-enhanced tip processing may represent an update to the “FALCON Tipline,” which replaced ICE’s previous tip-processing system around 2012. According to a DHS document last updated in 2021, the FALCON Tipline processes tips submitted by the public or law enforcement agencies about “suspected illegal activity” or “suspicious activity” to ICE’s Homeland Security Investigations (HSI) Tipline Unit.

When HSI receives a tip, investigators within its Tipline Unit conduct “queries” across various “DHS, law enforcement, and immigration databases.” After analyzing these results, HSI agents write “investigative reports” and then refer tips to the appropriate offices within DHS. The new AI system appears to streamline this workflow by automatically categorizing, summarizing, and translating incoming tips.

A DHS spokesperson told WIRED that ICE employs various technologies to aid “in the arrest of criminal gang members, child sex offenders, murderers, drug dealers, identity thieves and more, all while respecting civil liberties and privacy interests.” The spokesperson emphasized that Palantir has had federal contracts with DHS for fourteen years and currently provides solutions for investigative case management and enforcement operations.

The 2025 DHS AI Use Case Inventory, published annually since 2022, does not mention AI tip processing in its 2024 edition, suggesting this represents a new application of AI within the agency. The inventory’s publication follows growing scrutiny of federal agencies’ use of AI and the need for transparency in how these powerful tools are deployed.

Privacy advocates and civil liberties organizations have expressed concern about the integration of AI into immigration enforcement, particularly given Palantir’s controversial history with ICE. The company’s technology has been used to support deportation operations and track undocumented immigrants, leading to protests and calls for accountability.

The use of commercially available LLMs trained on public data raises questions about data security and the potential for bias in the AI’s outputs. While DHS states that no agency data was used to train the models, the interaction between the AI and sensitive tip submissions could still present privacy challenges.

As federal agencies increasingly turn to AI to enhance operational efficiency, the balance between technological advancement and civil liberties protection remains a critical concern. The deployment of Palantir’s AI tools by ICE represents just one example of how artificial intelligence is reshaping government operations, with implications that extend far beyond immigration enforcement.

The transparency provided by the AI Use Case Inventory represents a step toward accountability, but many details about how these systems function in practice remain unclear. As AI becomes more deeply integrated into government operations, the need for robust oversight and clear guidelines for ethical AI use becomes increasingly urgent.
