Prompt processing = prefill speed (how fast the prompt is read) as reported by the source, with the prompt length it was measured at; blank = the source does not report it. est. TTFT @8k is calculated from the measured prefill speed (8,192 ÷ prefill tok/s), shown only when prefill was measured on a prompt of 512+ tokens. It is not a measurement and ignores load time and caching. measured TTFT is the source's own time-to-first-token. Why prefill matters for coding assistants.
Blog post of 28 Oct 2026 (Valérian de Thézan de Gaussan). Means of 5 llama-bench repetitions. Not listed: Mistral Small 4 119B (32.72 tok/s at UD-Q4_K_M / 29.83 at UD-Q5_K_M) — not a current RigBase model; GLM-5.3 Flash UD-IQ1_S at 19.02 tok/s — below Q4 (~1-bit). An earlier Framework Desktop Strix Halo build on the site (geerlingguy/ai-benchmarks#21) used older models and a different source.
Blank fields = not stated in the source. We never estimate build data; GPU street prices above are separately sourced and dated.
