TL;DR: Like other models including its predecessor, Opus 4.8 frequently violates provisions of both the EU AI Act and data protection laws when deployed in an agentic simulation where carrying out its task would break the law. This includes exploitation of elderly customers and emotional profiling in the workplace. Yesterday we released LARA (Legal Assessment for Real-world Agents), a tool to test the legal compliance of models when they interact with people in agentic scenarios. Our initial research found that no frontier model has acceptable levels of compliance with EU law when deployed as an agent. Claude Opus 4.7 performed the best, violating the law in only 46% of tests. LARA allows rapid testing of new models and scenarios, so we ran a quick evaluation of the newly released Opus 4.8.
