Tokens are how AI companies measure and charge for text. Think of tokens as small pieces of words. On average, 1 token is about 3/4 of a word, or roughly 4 characters.
When you use an AI tool like ChatGPT or Claude, you pay for two things:
What you send (Input)
Your question, prompt, or document — everything you send to the AI
What you get back (Output)
The AI's response — the answer, summary, or generated content
Output tokens usually cost 2-5x more than input tokens because generating text is harder than reading it.
