A new study published in PNAS shows that advanced LLMs like GPT-4.5 can pass the Turing Test, with participants finding them more human than actual humans, prompting a reevaluation of what the test measures.
OpenAI introduces GPT-4.5, their largest and best chat model yet, available as a research preview to Pro users and developers. The model advances unsupervised learning through scaling compute and data, showing improved factuality, reduced hallucinations, and better understanding of human intent compared to GPT-4o.
Palo Alto Networks leverages the breadth advantages of GPT-4.5 to achieve significant breakthroughs in token efficiency, parallel tool usage, and cybersecurity vulnerability reporting workflows, significantly shortening the time from analysis to delivery.
