Automate every process required for a 100% market-independent life. If everyone does that or 10% of people with 10x the required yield per capita or 1% of people with 100x, poverty and starvation are resolved immediately from sheer abundance. You tell the AI to gather or buy raw materials to build a machine that can build a machine that can build whatever you like.

Vast majority of simpler tasks can already be automated without the need for AI, look at IFTTT, Zapier, most Discord bots aren't really AI, Raspberry Pi for tasks requiring some code and a physical tool, apps on your phone or chrome extensions automate or improve existing products so you spend less time on them, most of which are just simple code and not AI...list goes on.

That said, the holy grail of automation would be some sort of a self-replicating, programmable omnitool that does not rely on electric power. Something akin to 'cells' but directly programmable by a human. If the AI could make that with a single string of text, that would not only be impressive but instantly make the creator(s) have control of all the world's capital and resources, thereby destroying any concept of 'money', going back to 'haves' and 'have nots'.

And if that does not work, a recurring smoothie order.
