US notice directs civilian agencies to remove DeepSeek products

On October 20, the Federal Register published a notice describing a Homeland Security order that excludes DeepSeek products from federal civilian procurement. The order also covers affiliate products and third-party services developed using DeepSeek implementations.

The publication date is not the date the underlying order was issued. This is a federal civilian procurement and IT restriction, not a ban on every private US user.

UNIDIR plans an October 22 forum on military AI

UNIDIR plans to open participation in a new AI, Peace and Security forum in New York on October 22. At an October 20 press conference, director Robin Geiss warned that military AI is narrowing the room for human judgment, AP reported.

UNIDIR opened the research centre in June. This week's event is the forum, not the research centre's creation. A discussion forum does not create a binding treaty or verify military compliance.

METR backs low-risk finding, questions Anthropic's tests

METR published a review of Anthropic's August risk report on October 20. It agrees that misalignment risk was low for the covered models, deployed before July 15. It doubts the report's methods would reliably detect a higher risk level.

This was a limited review of an internal report, not the broader access announced later. Anthropic could veto publication or redact the review. METR says no redactions occurred and its conclusions did not change.

FairStress tests whether AI changes its decisions under pressure

The Allen Institute for AI introduced FairStress on October 20. Its 300 decision scenarios cover 29 domains. The benchmark asks whether matched arguments change a model's choice differently when candidates' demographic identities change.

These are the authors' research results, not an independent audit of real hiring or lending. The benchmark tests one definition of fairness, based on equal criteria and equal resistance to persuasion.
