Measured speed (generation tokens/sec)
| Model | Quant | Engine | tok/s | Prompt processing (tok/s) | Details |
|---|---|---|---|---|---|
| GLM-5.3 Flash | EXL3 4-bit + DFlash2 | TensorFold, 2 nodes, 1 stream | 60.4 | 1,979 @ 32k-token prompt est. TTFT @8k ≈ 4.1 s (calculated from measured prefill) | ⚡ spec-decode (DFlash)context: 1M📏 Single-stream decode as published on Mia's AI Lab recipe card (Decode speed, one stream). Peak throughput 108.8 tok/s ×4 streams. |
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.
Recipe and numbers by Mia's AI Lab (mia-ai.net), recipe last updated 2026-10-25; RigBase read the recipe card on 2026-10-27 and checked the decode figure against the recipe page. RigBase did not re-run it. Prefill is prompt-processing speed on a 32k prompt where listed.
