Models update every few months. Knowing the version matters because behavior, price, and limits all change between releases.
AI labs ship new model versions constantly — Claude 3, 3.5, 4, 4.5, 4.7; GPT-4, 4o, 5, 5.1; Gemini 1.5, 2.0, 2.5. Each version has different strengths, prices, and quirks. APIs let you pin a version; chat apps usually default to the latest.
Check which model your favorite chat app currently uses (in settings). Note the version. Now you'll notice when it changes.
