Add Text Files

This is not an official feature of OpenAI's API. This is simply a conveniece feature to help you add multiple text files to your user prompt easily. Files are not uploaded; the text is extracted as plaintext. Edit start and end separators as needed. The concatenated content of all files with separators is added to the token count and cost automatically. Add to the prompt text if you want to see the full prompt with files and separators in the preview.

Understanding GPT-4 Tokens

Tokens in GPT-4 serve as the basic units of processing, representing words, parts of words, or punctuation. Understanding these tokens is crucial for effective and cost-efficient use of AI language models.

The Role of js-tiktoken Library

The js-tiktoken library is integral to this application, encoding text and images into GPT-4 tokens. This calculation helps estimate the cost for processing data through OpenAI's GPT-4 API.

How the GPT-4 Token Calculator Web Application Works

This user-friendly application facilitates free prompt text input and image uploads, displaying token counts and calculating costs based on the data provided.

Text Input Handling: Encodes text into tokens, displaying the count and calculating the cost.
Image Upload and Processing: Processes uploaded images to determine token requirements.
Token Calculation for Images: Calculates tokens based on image size and specified tile size.
Total Cost Calculation: Summarizes the total expense for using GPT-4's capabilities.

Tokenization & AI Development

This application is a valuable tool for planning efficient and cost-effective projects involving AI language models, showcasing the potential of combining web technologies with AI computation tools.
