What about a longer context?
An estimate, not a measurement: the KV cache grows with context, takes VRAM and slows generation down.
| Context | KV cache | Estimated VRAM | Fits in 12 GB? | Estimated speed |
|---|---|---|---|---|
| 4 096 | 0,5 Go | 6,0 Go | yes | ≈ 77,3 tok/s |
| 8 192 | 1,1 Go | 6,5 Go | yes | ≈ 70,7 tok/s |
| 16 384 | 2,1 Go | 7,6 Go | yes | ≈ 60,3 tok/s |
| 32 768 | 4,3 Go | 9,7 Go | yes | ≈ 46,6 tok/s |
| 65 536 | 8,5 Go | 14,0 Go | no | — |
| 131 072 | 17,0 Go | 22,5 Go | no | — |
KV cache per token = 2 × 34 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”
