While LLMs excel at generating cogent text based on their training data, they may also need to interact with external systems. Function calling allows them to construct such calls. The LLM does not execute these calls directly, instead it creates a data structure that describes the call, passing that to a separate program for execution and further processing. The LLM's prompt includes details abou

WCAG 3.0’s Proposed Scoring Model: A Shift In Accessibility Evaluation — Smashing Magazine
WCAG is evolving. Since 1999, the Web Content Accessibility Guidelines have defined accessibility in binary terms: either a success criterion is met or not. But real user experience is rarely that simple. WCAG 3.0 rethinks the model — prioritizing usability over compliance and shifting the focus toward the quality of access rather than the mere presence of features. Could this be the start of a ne
