The car wash test evaluates AI reasoning by asking whether to walk or drive 50 meters to a car wash. Most leading AI models, including Claude Sonnet 4.5, GPT-5.1, Llama, and Mistral, fail to provide the correct answer, which is to drive.

Top AI models can generate near-verbatim copies of bestselling novels, indicating that they memorize more training data than previously understood. This memorization capability raises legal concerns regarding copyright and the implications for AI developers.

GPT-5.2 proposed a formula for a gluon amplitude that was later verified by an internal OpenAI model. The research demonstrates that a previously unexpected particle interaction can occur under specific conditions, focusing on gluons, which carry the strong nuclear force.

OpenScholar synthesizes scientific research and accurately cites sources, achieving a level of accuracy comparable to human experts. In a study, researchers found that the AI model significantly reduces the issue of hallucination seen in other models like GPT-4o, which fabricated 78-90% of its outputs.
