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 ~15068.2-18170.5 tok/s and fits up to 856k context; beyond that it spills to SSD swap and slows to ~276-332.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 856k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
