LLMs on device is the future. It's more secure and solves the problem of too much demand for inference compared to data center supply, it also would use less electricity. It's just a matter of getting the performance good enough. Most users don't need frontier model performance.
SSD weights offload makes it feasible to run SOTA local models on consumer or prosumer/enthusiast-class platforms, though with very low throughput (the SSD offload bandwidth is a huge bottleneck, mitigated by having a lot of RAM for caching). But if you only need SOTA performance rarely and can wait for the answer, it becomes a great option.
