You could set up swap space on Intel Optane media, it'll be about the same performance as DDR3 and sells for ~$1/GB on the secondary market. Though it will be a lot more power hungry than Flash, let alone DRAM - so not suitable for all uses.

Doesn’t that require an Optane capable system?

Optane is a technology I’m still mad never became mainstream. It would be particularly useful today when trying to run local models.

Optane is available in NVMe form factor that will work basically everywhere. There's also Optane persistent DIMMs that only work in highly specific systems.
