## Description

This project functions as a transparent reverse-proxy gateway designed to provide unified access to various large language models. By acting as a stateless intermediary, it forwards client requests to upstream providers without logging or storing any user prompts, ensuring that interaction data remains private throughout the transmission process.

The service distinguishes itself by offering a standardized interface that normalizes diverse AI model request formats, allowing users to integrate a consistent backend across a wide range of third-party applications. It supports flexible configuration through base URL injection, enabling developers to redirect traffic from desktop clients, IDE extensions, and automation platforms to this centralized gateway.

The platform provides a reliable alternative for model consumption, featuring a pay-as-you-go billing model based on official token usage metrics. This approach allows users to access high-performance model services without the constraints of traditional subscription plans.

To facilitate integration, the project maintains an extensive directory of configuration guides for popular AI development tools, chat clients, and productivity software. Users can connect their preferred applications by updating the service endpoint settings to the provided gateway address.
