What about a longer context?

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

KV cache per token = 2 × 8 layers × 4 KV heads × 256 × 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”
