They say their work represents the first demonstration of "quantum enhancement" in a production\-scale, pretrained large language model \(LLM\)\. One of the key metrics used to measure the quality and capabilities of AI systems such as Anthropic's Claude, OpenAI's ChatGPT and similar services is a unit known as "perplexity" — often expressed as PPL\. This measures a system's general ability to properly predict the next word in a sentence or sequence of words\. Get the world’s most fascinating discoveries delivered straight to your inbox\.
