Greasy Fork is available in English.
Automatically force GPT-4o, even if switched back to GPT-5
Forces ChatGPT to always use the GPT‑4o model, even if it automatically or manually switches to GPT‑4 or GPT‑5. Adds a toggle button next to the model switcher to enable or disable this behavior. The script monitors DOM changes and selects GPT‑4o automatically when needed. Ideal for users who prefer GPT‑4o’s performance and want to avoid unexpected model switches.
