What it is

A tool to estimate the number of tokens an OpenAI chat completion request will use, aiding in cost management and optimization.

OpenAI Chat Tokens offers a straightforward way for developers to predict and manage costs associated with using OpenAI's chat completion API by estimating the number of tokens used in requests.

When it fits — and when it doesn’t

A good fit for

  • Developers integrating OpenAI chat completions into cost-sensitive applications

  • Teams needing precise control over API usage costs in production environments

  • Individuals learning about the intricacies of tokenization and its impact on API costs

Look elsewhere if

  • Projects that do not use or plan to use OpenAI's chat models

  • Applications where real-time token estimation is critical (as this tool provides an estimate, not exact counts)

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support beyond JavaScript

    Primary documentation and examples are in JavaScript, with limited official support for other languages.

  2. 02

    Complex setup for non-trivial use cases

    Integrating the tool into complex projects requires significant configuration and understanding of token estimation nuances.

  3. 03

    Poor documentation for advanced features

    Advanced usage patterns, such as custom models or fine-tuning parameters, are not well-documented.

  4. 04

    Performance issues with large inputs

    Estimating tokens for very long text inputs can be slow and may exceed reasonable response times.

What it does well

  • Estimates token usage for OpenAI chat completions

  • Helps manage costs by predicting API usage

  • Easy to integrate into existing projects
