llama.cpp switches lazy-mode default to auto: 51B-param embedding table stays on disk

whiteh4cker · reddit · 2026-09-01

Starting with b10726, llama.cpp's default --lazy-mode is now auto: the 51B-parameter PLE n-gram embedding table of Qwen 3.5 Flash Next is no longer loaded into RAM but mmap'd and read from disk on demand during inference, even with --load-mode none. Pass --lazy-mode off to restore the old eager loading behavior.
