AI na świecie - najważniejsze wydarzenia z 21 października 2026

Today's Daily AI World Brief gathers the most important news about artificial intelligence from key regions of the world.

The focus is on business implementations, regulations, security, and the development of AI models.

Europa Not Self-Decidable: LLMs Cannot Draw the Boundary of What an Agent Verifier Can Check arXiv:2610.04699v2 Announce Type: replace Abstract: A verifier for an agent faces rules of two kinds: the ones a fixed check can settle and the ones that require a judge.

A team that derives its own checks fixes that split up front.

Where the requirements come from outside, as in finance, healthcare and law, the agent enforces rules it did not write, so the split falls to runtime, recurring for every predicate of every rule on every action at a rate no reviewer can audit.

Every escalation scheme assumes a model can make that decision itself, that it is self-decidable.

Across six corpora, including the EU AI Act, FINRA guidance and a deployed credit agent, we collect roughly 22,000 labels from four models built by three labs.

They agree almost perfectly where the answer is obvious and collapse on regulatory text; their errors run in opposite directions, so no model can be trusted as the conservative choice; and on the deployed agent's own rule-set they err together, over-claiming that a fixed check will do, the direction that never gets escalated.
