Throughput note. llama.cpp rows include prompt-processing tokens/sec and decode tokens/sec from same-artifact llama-bench measurements. Direct QVAC logs exposed completion token counts and wall-clock request times, so the report shows a separate observed output tok/s field for QVAC; QVAC did not expose a comparable prompt-processing tok/s measurement in the run logs.

Speed, Tokens, And Footprint

Use this table for phone-fit tradeoffs: quality score, VRAM, latency, total benchmark tokens, prompt-processing speed, decode speed, and QVAC observed output throughput.
