Bypass Membership Limits: Access Overseas LLMs Easily with Chatbox

Background

Domestic users can conveniently use local large‑model services (e.g., Doubao, Deepseek, Tencent Yuanbao, Alibaba Qianwen), but membership requirements prevent direct access to overseas models such as ChatGPT, Gemini, Claude, and Grok. To quickly experience these overseas models, four solutions are proposed, and the third solution—using an open‑source desktop client with a proxy API—is chosen.

Basic Introduction

The chosen desktop client is Chatbox , an open‑source AI chat application that supports multiple language models.

Core Features

Cross‑platform support for Windows, macOS, and Linux.

Compatibility with many models, including OpenAI GPT series, Claude, and any service that follows the OpenAI API format.

Localized interface with Chinese and other languages.

Main Functions

Chat session management and conversation history.

Custom API configuration allowing users to set their own API keys and endpoints.

Support for locally deployed models.
