Environment Variable Configuration Guide

This document provides all environment variables supported by 88API and their configuration instructions. You can customize the system's behavior by setting these environment variables.

Tip

88API supports reading environment variables from the .env file. Please refer to the .env.example file and rename it to .env for use.

Tiktoken File Configuration

After downloading the tiktoken files, please rename them as follows:

cl100k_base.tiktoken renamed to 9b5ad71b2ce5302211f9c61530b329a4922fc6a4
o200k_base.tiktoken renamed to fb374d419588a4632f3f557e76b4b70aebbca790

These files should be placed in the directory specified by TIKTOKEN_CACHE_DIR to improve token calculation performance and reduce network dependency.

Tiktoken Configuration Example

# Docker environment example
TIKTOKEN_CACHE_DIR=/app/data/tiktoken

  # Then download and rename the tiktoken files and place them in this directory:

# /app/data/tiktoken/9b5ad71b2ce5302211f9c61530b329a4922fc6a4

# /app/data/tiktoken/fb374d419588a4632f3f557e76b4b70aebbca790

Tiktoken is the tokenizer used by OpenAI to calculate the number of tokens in the text. By caching these files locally, the system can avoid downloading them from the network every time it starts, improving stability and performance, especially in network-restricted environments.
