Where the speeds come from

Prompt estimated from median of 6 measured prefill points for this device (llama.cpp ROCm), rescaled to this model.
Generate estimated from median of 6 measured decode points for this device (llama.cpp ROCm), rescaled to this model.
First token 4K-token prompt ÷ estimated prefill speed. Excludes model load and queueing.

Caveats

KV-cache size could not be established from the config (compressed or backend-specific attention).
Fixed recurrent/convolution state is unknown and not included.
