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.
kksoftwareag project docs, as of 16 Sep 2026. The source also runs a second engine (halogen-flash-server, 35.9 t/s single user with its own 5.53-bit checkpoint); not listed here because whether that figure uses its MTP head is not stated. MTP lowers total throughput once two or more users share the box.
