Token Counter by Model
Count tokens for any AI model in real time. Paste your prompt to see exact token counts for OpenAI models or fast estimates for Claude, Gemini, and more.
Token Counter by Model lets you measure the exact token length of any prompt or text across 30+ AI models — including GPT-5.5, Claude Sonnet 4.6, Gemini 3.1 Pro, and more. Knowing your token count before sending a request helps you stay within model limits, estimate API costs accurately, and avoid unexpected truncation.
Unlike generic word counters, this token counter uses the native BPE tokenizer for OpenAI models, running entirely in your browser with no data sent to any server. For Claude, Gemini, Llama, and other providers, it applies model-specific character ratios that reflect how each tokenizer splits text in practice.
Paste your prompt below, select a model, and get an instant token count alongside the estimated word and character equivalents.
