About Token Calculator
Thinking in tokens is the new literacy of the AI age. We built Token Calculator to help developers, researchers, and businesses accurately estimate costs and optimize prompts for Large Language Models.
Our Mission
As LLM pricing models become more complex and context windows grow larger, "eyeballing" costs is no longer sufficient. Our mission is to provide a transparent, precise, and secure toolset for the AI community.
Why Trust Us?
- Engineering Precision: We use the exact BPE (Byte Pair Encoding) tokenizers (
tiktoken) used by OpenAI models, ensuring 100% accuracy for GPT-4 and GPT-3.5. - Privacy First: We understand that prompts often contain proprietary code or sensitive PII. That's why we engineered our tool to run client-side only.
- Up-to-Date Pricing: We continuously monitor API pricing changes from major providers (OpenAI, Anthropic, Google) to ensure your cost estimates are current.
The Team
Token Calculator is maintained by a small team of AI engineers and web performance experts passionate about the open web.
