Do you love C programming but feel left out from the AI boom?
Say hello to openai-c — a lightweight, dependency-minimal, MIT-licensed C client for the OpenAI Chat API.

✨ What is OpenAI C?

openai-c is a minimal wrapper around OpenAI’s Chat Completion API, written in pure C11. It lets you send prompts to models like gpt-3.5-turbo and get back responses — all without leaving your beloved C codebase.

🚀 Features

• Written entirely in C (C11 standard)
• Supports gpt-3.5-turbo and customizable model names
• Simple API: openai_init(), openai_chat(), openai_cleanup()
• Uses libcurl and cJSON
• Lightweight and fast
• MIT licensed

🧩 Basic Usage

#include <stdio.h>
#include "openai.h"

int main() {
    openai_init("your-api-key");

    char* res = openai_chat("Hello, who are you?");
    if (res) {
        printf("OpenAI says: %s\n", res);
        free(res);
    }

    openai_cleanup();
    return 0;
}
