You can buy sub-$0.50 microcontrollers. But even at $5, I don't know why you'd want to run models on them, it's an environment constrained to the point of being useless for this task.

And I hope it stays that way, I don't want MCU shortages...

Fun and learning is a really good reason. It also reminds me of the damascene: trying to achieve something that doesn't feel possible, and working through all the extreme resource-constrained engineering limits.

I think most of my embedded projects aren't that useful, but they've taught me a lot.

		I'm not disagreeing with you, I think this goes beyond impractical, it's doomed from the get go. In my book, impractical means "I built a cuckoo wristwatch". Beyond impractical: "I built a cuckoo wristwatch but there was no room for a working mechanism".

I want to run music models on the Milk-V and have them jam in realtime with me.

isn't floor price 0.10$ for last couple years?

		Well, that's sub-$0.50. But yeah, CH32V003 is in that ballpark, and some of the cheapest Microchip and Infineon products are around $0.20. It's almost never worth it to buy the cheapest chip unless you're making a million of something, but there are very good ones around $1-$2, and $5 is the upscale stuff.
