This. I have no problems to combine couple endpoints in one script and explaining to QWQ what my end file with CSV based on those jsons should look like. But try to go beyond that, reaching above 32k context or try to show it multiple scripts and poor thing have no clue what to do.
If you can manage your project and break it down to multiple simple tasks, you could build something complicated via LLM. But that requires some knowledge about coding and at that point chances are that you will have better luck of writing whole thing by yourself.
I would say, that 16gb is barely enough, if you planning gaming. UE5 games can easily fill up that, so if you wanna have game recording or browser in background, then above 16 is mandatory. Maybe at least 24gb.
