Replacement for GPT-4o in the OpenAI GPT Plugin

[Jim Kirkpatrick]

OpenAi is retiring GPT-4o:

"On February 13, 2026, alongside the previously announced retirement⁠ of GPT‑5 (Instant and Thinking), we will retire GPT‑4o, GPT‑4.1, GPT‑4.1 mini, and OpenAI o4-mini from ChatGPT. In the API, there are no changes at this time"

In the OpenAI GPT Plugin setup changing gpt-4o to gpt-5.2 has no obvious effect. Looking at the config file for the plugin, it appears that gpt-4o is hardwired there. Will it be updated or is there a way to get the system working on gpt-5.2?
