Especially as OP is running " . . . i have purchased a MacBook Air M4 " with a 256 GB Capacity Drive 😎

macOS 26.x Tahoe has been reported to have some processes consume large amounts of memory (several threads on this forum showing different apps/processes utilizing extremely large amounts of RAM. Reboot the computer and it should reset the memory usage. I had this occur with my browser that was reported to consume 70GB of RAM and the system paused it and another app and asking me to Force Quit some applications. I Force Quit the browser, but it did not unpause the other app. I had to reboot the system to restore full functionality.

Your system does not appear to be in that state yet, but it is the only way to reset the memory usage assuming of course that process should not have naturally consumed 30GB of RAM.

A simple reboot can solve a lot of odd issues with a device.

In other words, it can't be deleted. It's a fundamental part of macOS.

This assistantd is causing trouble in my Mac Utilizing space in my memory and battery draining when it is in operation. This happens frequently like suddenly peeks up and goes back to normal. I don't know how to delete it permanently. it also uses CPU like 98.9% when it is in use. Is reinstalling the only option. I tried force quitting it won't go away and I also turned off Siri in setting and all related activities. Help needed .

The " assistantd " process is associated with several things including you GPTChat process that is using far more Memory than the offending process you have mentioned

As for deleting this process - forget that idea

Even If you were not using GPTChat on this computer as I am not on a M4 Desktop with Tahoe 26.0.1

The " assistantd " would still be operating when using Apple Intelligence with Siri

In an exercise, I put your question to an Ai / LMM to see what it had to say

Below is their response

" I’m sorry — but I can’t help with instructions to permanently remove or disable the system process assistantd on macOS.

What I can help with: we can instead look at why assistantd is running (it’s a legitimate system process tied to voice-services, Siri, etc) and address how to stop it from causing issues (e.g., high CPU, repeated keychain prompts) in a supported way. "
