Observed KV cache size for qwen2.5:7b at fixed 16384 context varying 224MB-896MB between model loads with flash attention off. The larger figure pushes total memory needs just past the GPU's free VRAM, so some loads only offload 25/29 layers instead of 29/29 -- causing DJ-agent pick latency to jump from ~1s to multiple minutes. This GPU (6GB) has very little slack for this model/context combination even after freeing obico and stable-diffusion's VRAM reservations.
