What about a longer context?

An estimate, not a measurement: the KV cache grows with context, takes VRAM and slows generation down.

ContextKV cacheEstimated VRAMFits in 16 GB?Estimated speed
4 0960,6 Go6,6 Goyes≈ 133 tok/s
8 1921,1 Go7,2 Goyes≈ 121 tok/s
16 3842,3 Go8,3 Goyes≈ 102 tok/s

KV cache per token = 2 × 36 layers × 8 KV heads × 128 × 2 bytes (f16). Estimated VRAM = measured VRAM + added KV cache. Speed ≈ measured speed × weights ÷ (weights + added KV cache) — attention compute is not modelled, the real drop is slightly larger. Fine-tune it in the “Configurator”
