AI Token Counter
Estimate tokens and API cost for GPT-4, Claude, Gemini, Llama and other LLMs. Estimate uses ~4 chars/token (industry rule of thumb).
// How Tokens Work
LLMs split text into tokens (subwords). English averages ~4 characters or 0.75 words per token.
// Why It Matters
You pay per token. Long prompts and verbose outputs add up fast on production workloads.
// Estimation Note
This is a fast approximation. Use OpenAI's tiktoken or Anthropic's official counter for exact billing.
// Tips
Trim system prompts, request JSON instead of prose, and use cheaper models for classification.
