Complete field report on Strata v0.1.42–v0.1.43: 15 verified speed/depth rows (canonical prompts, cold prefill, MTP), and three full quality evals — HellaSwag 92.66%, GSM8K 98.10%, ARC-Challenge 98.43% — all 13/13 shards approved. 180B MoE on 2x16 GB consumer GPUs via expert streaming.
Verified UD-IQ4_XS speed suite on Strata v0.1.43.1: reasoning 105.7 / code 107.6 tok/s (TTFT 649/589 ms), verified-at-depth decode 101.4/100.8/94.3 tok/s at 16k/65k/131k with cold prefill 3.2–3.7k tok/s. All five runs verifiedRun:true; full contamination-handling disclosure included.
Five weeks taking Qwen3.8-27B on a single Tenstorrent Blackhole P150 from 7.7 tok/s to ~50-55 tok/s single-stream decode (DFlash2), ~1,200 tok/s prefill and native 262K context, using a custom mixed BFP4/BFP8 quant (now GPTQ). Covers the quant, every speed-test milestone, quality checks, power and thermal data, the dead ends, lessons learned and what's next.
Qwen3.8-27B on two RTX 3060 12GB cards, llama.cpp 0.4.1-dev. Measured 129,000-token synthetic prompt at 497.8 prompt tok/s and 42.7 output tok/s mean, with exact recall of 3/3 canary facts in two runs. Configured context 131,072; ngram-mod + MTP3; batch 2048, ubatch 512.
vLLM 0.29 on a 64GB CMP 170HX. AutoRound W4A16 + DFlash2, production max-model-len 131072. 133 tok/s short decode, 98 tok/s with a 7.3k prefix. Not an 8k-ctx speed-run.
A 65,100-token prompt on a single 16 GB card: 4-bit KV cache (1.1 GB for the whole context), host-staged embedding table, 99 s TTFT (was 146 s before the flash-attention fix), 23.46 tok/s decode, 14.24 GB peak. Speculative decoding is unavailable past 4K context by design.
