It's essential for developers optimizing prompts and managing API costs."},{"question":"How do I use LLM Token Counter?","answer":"Paste or type your text in the input area, select the model or tokenizer you want to estimate for, and the tool shows the token count and estimated cost in real time. Compare counts across multiple models simultaneously."},{"question":"Why do token counts differ between models?","answer":"Each model uses a different tokenizer with its own vocabulary and encoding rules. For example, GPT-family tokenizers differ from Claude-family tokenizers. The same text can produce different token counts, which directly affects API costs."}],"howTo":[{"title":"Paste text to count","description":"Paste any content: prompt text, article, code snippet, or conversation.
