Why do different models give different token counts?

Each model family uses its own tokenizer, so the same text splits into a different number of tokens. That directly affects cost and how much fits in a request.

Are the counts accurate?

Yes. ChatGPT uses OpenAI's public tiktoken encoding, and Claude and Gemini use each vendor's official count API — none of them is an estimate.

LLM tokenizers

Token counts drive both cost and context limits, and every model tokenizes text differently. These tools give you the exact count per model — ChatGPT in your browser with the open tiktoken encoding, Claude and Gemini via each vendor's official count API — so you can budget prompts and compare models with confidence.
