For very very long waiting time

First of all, It takes a very long time for me to get an answer for my questions, especially when I am using ChatGPT-5.2 as the targeted AI and asking the coding questions (this problem also happens when I am using other AI and asking simpler questions). It takes too long that the website shows no response and forces me to reload the page.

Secondly, also talking about the ChatGPT-5.2, sometimes it shows errors when I ask questions which force me not to use ChatGPT-5.2 as the targeted AI. You can see the error message in the appendix.

Lastly a small suggestion for the text box for us to type the question for AI, could it be set as a client side display instead of server side. As it already takes a very long time for loading, if the text box is kept as the server side, it's quite frustrating for us to type and wait so long to see what we have typed.
