The LLM you use to help you in your work and the LLM you use to power a feature in your app will likely be different.

The LLM you use for work you'll want to be the very best.

You're only using it a capped amount (there's only so much one individual can use it), so the extra cost isn't the end of the world.

The LLM you use for the feature in your app you want to be as cheap as you can while still being good enough.

You could get possibly uncapped usage.
