When using ChatGPT as a search engine, in the browser, and tagging a GPT in the prompt/query, it does not trigger the GPT. It should Trigger it.
In the Web UI for ChatGPT, it allows you to tag a GPT, for example Consensus AI GPT with @Consensus, when using the ChatGPT search engine in the browser, if you type @Consensus that GPT is not triggered.
