chatGPT tab loads my CPU to 200%

Hello, I am on Linux Mint with Google Chrome stable. I’m using chatGPT at chatgpt dot com and the burning problem I have is when I communicate to it (the page is not idle) - this tab loads my CPU to 200%, the core sensors report temperatures of over 90 C and then I have to close that tab to cool off. What is the problem, why it needs to be that way??
Who can fix that and is there anything that I can do?
