internal OpenAI Astra model has reportedly solved ten significant open problems in mathematics and computer science. The effectiveness of AI financial advice has been noted as surprisingly good, particularly when users pose the right questions. A recent study indicates that only 8.9% of websites actively block AI crawlers, yet a vast majority. 8%, are not cited in AI-generated answers. The proliferation of generative AI is causing a dilution of the market for books. A personal benchmark for AI capability involves generating an SVG of a frog with a Habsburg jaw. EU's new rules on AI models are now enforceable, prompting questions about upcoming changes.
