The Download: meet the judges using AI, and GPT-5's health promises

The propensity for AI systems to make mistakes that humans miss has been on full display in the US legal system as of late. The follies began when lawyers submitted documents citing cases that didn't exist. Similar mistakes soon spread to other roles in the courts. Last December, a Stanford professor submitted sworn testimony containing hallucinations and errors in a case about deepfakes, despite being an expert on AI and misinformation himself. Now, judges are experimenting with generative AI too. Some believe that with the right precautions, the technology can expedite legal research, summarize cases, draft routine orders, and overall help speed up the court system, which is badly backlogged in many parts of the US.
