Note on terminology: Throughout this video, I use the term "credits" as a broad, tool-agnostic way to describe the resources consumed when generating AI output. Depending on the tool, those resources may be measured through tokens, computing power, advanced reasoning features, data limits, message limits, or other usage-based measures. Because each AI product has its own pricing and usage model, "credits" is the simplest term to use across platforms and the easiest for learners to understand.
