How to Connect GPT-5.6 to Claude Code

rickasaurus · x · 2026-07-13

The post shares a method to integrate GPT-5.6 into Claude Code: by configuring a proxy via CLIProxyAPI, pointing Claude Code to gpt-5.6-sol, and running the provided alias command, it can be set up in about 5 minutes.

The core information isn't about the model itself, but rather this "cross-tool invocation" development workflow: using a proxy layer to plug external models into an existing coding environment, making it convenient for developers to try out other models directly within Claude Code.
