Long-context results

Qwen3.8-27B-filled16k · llama.cpp. Each row is a point this run measured, keyed on the prompt tokens the runtime counted (the depth of context the prompt filled).

Prompt tokens are not the configured context capacity. “—” means unmeasured or unavailable.

Scroll the table sideways for all measurements.

Long-context measurements and status for each measured prompt length.
Actual prompt tokens	First token (s)	Decode tok/s	Output tokens	Status

First-token delay includes processing the prompt with the model loaded. These speed measurements do not test answer quality or the maximum usable context.

Reproduce on your machine

Start with this model and workload selection. This command does not capture the original artifact, backend version or server settings:

Match quantization, context capacity, caching and runtime settings for a useful comparison. Duration varies by workload and hardware; the published client may differ from this run's version. How it's measured.
