I still have it in my TODO list. Recently I bought OrangePI 5 max that has rk3588 SOC in it. It's far from ideal though how rockchip (and others along the chain) do the support. It's half baked, half glued software with blob bootcode from China. Even u-boot relies on rockchip's blob SPL. I treat it with certain level of scepticism. And yes, I know even RPI is not opened in this regard.thank you for sharing the name of the projec
It's powerfull little thingy though.
Starting point for this project in my case: rknn. But basically I'd need to google how to setup local LLM with this chipset. There are some YT videos for this board where people tested chat bots on this.
