GPT-family counts are exact — they use the same open o200k tokenizer as the models. Anthropic and Google keep their tokenizers private, so those counts are clearly-labeled estimates (Claude typically tokenizes ~10–20% above o200k; use Anthropic's free count_tokens API endpoint for exact numbers). Prices come from each provider's public pricing page — follow the links on the model pages to verify. Everything runs in your browser; your text is never uploaded.
