If you have a Steam Deck, it may be your best hardware for a "we have local llm inference at home"-server

Key Points

  • The Steam Deck's 16 GB of soldered DDR5 RAM may outperform typical PC CPU RAM for small LLMs, as long as the model fits in memory.
  • CPU inference remains viable for models that fit within 16 GB, making the device a low-power alternative for at-home local inference.
  • For users without a high-VRAM GPU, the Steam Deck could function as a practical local LLM inference server at home.
  • The discussion centers on LocalLLaMA usage and suggests Steam Deck might be the best available option for local, non-remote inference in some setups.

I find this kind of funny. Obviously not if you have a spare >12GB VRAM machine available, this is mainly a "PSA" for those who don't. But even then you might want to use those resources for their main purpose while some inference runs.

The Steam Deck does not have much RAM, but it has 16 GB *soldered* DDR5. This would likely be better than the CPU RAM in your regular PC, as long as the model fits in at all. And CPU inference is perfectly viable for stuff that must fit into 16 GB. Also it is a low power device. Thoughts?
