Q4 yes 839k 99-119.3 t/s ~1.8-2.2 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

Yes. At Q4 it generates ~99-119.3 tok/s and fits up to 839k context; beyond that it spills to SSD swap and slows to ~1.8-2.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 839k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
