chatgpt5-codex/chatgpt-5.6-ai-free-desktop

This repository offers a desktop application that claims to provide free access to a model it calls ChatGPT 5.6, described as OpenAI's latest AI model, for tasks like reasoning, creative writing, and coding help, inside a native desktop window rather than a browser tab. The README states it works by using API reverse proxies and custom web interface wrappers rather than an official OpenAI subscription or API key. According to the project, the app supports Windows 10 and 11, macOS, and Linux, and needs an active internet connection to function. Installation involves downloading a zip file from the repository's releases page, extracting it, running the application, and following in-app instructions to configure access to the model. The listed features include full model access, coding and debugging support, content generation, a clean interface, and the ability to export conversation history. The README itself flags this as an unofficial client, stating plainly that OpenAI may change or restrict this kind of access at any time, and it recommends users only download the file from this specific repository and scan it with VirusTotal, a malware scanning service, before running it. Readers should treat that warning seriously: this project is not affiliated with or endorsed by OpenAI, it depends on workarounds the README does not fully explain, and using unofficial reverse proxy tools to access a paid AI model for free carries real security and legal risk, since it may violate OpenAI's terms of service and there is no way to verify what the reverse proxy service on the other end is actually doing with your data or conversations. The project is credited to a single author under the username yuzunes and is released under the MIT license. Beyond the setup instructions and feature list, the README does not describe the underlying reverse proxy mechanism, its infrastructure, or how reliable ongoing access is likely to be.
