For the LLMs uninitiated - I checked and ChatGPT Plus costs 20$/month, which puts it into same category as those services others build. Is this what you meant by having a subscription?

If I don't use ChatGPT for other purposes it seems like same prices to me, without the hassle of setting it up and tweaking. Or am I missing something?

A lot of HN users already have subscriptions to one of these LLM services.
