What
Follow-up to #901. Lowers
footprintinsrc/model_list.jsonfor the Qwen3.5 models whose token embeddings are now memory-mapped, and says in the model cards that only these three are covered.The 9B and every other model are unchanged: they still keep their embedding tables in RAM (noted on the cards).
How measured
Linux XRT, default 32768 context,
flm serve, one chat round, old engine libraries vs the shipped (#901) ones. Process RSS (VmRSS) after chat:Decode speed is unchanged (45.8 / 27.9 / 15.2 tok/s, old and new).
The old footprint values do not equal any single RSS figure I could reproduce, so the new values are the old ones minus the measured saving, rounded up to 0.1 GiB.
Windows and HRX were not measured.
