is ChatGPT app using my CPU/GPU for hidden computation?

I was randomdly checking the Activity Monitor on my MacBook Pro 14-inch, Nov 2023 with Apple Silicon M3. I noticed the native macOS app of ChatGPT taking 10-20% of the CPU while it's not in the foreground...

Is it just really inefficient or doing a ton of http calls without reason?!

Is it possible chatGPT is offloading a bit of computation to my machine?!

Can you also check on your machine and let me know?
