I have a ChatGPT Plus membership that allows me to use the GPT-5.4 model. However, when I choose the “ChatGPT (Web)” option, it defaults to GPT-4, which lacks reasoning capabilities, even though it still accesses my account. Unfortunately, the plugin panel doesn’t seem to offer any way to switch to the newer GPT model.
