OxCoder-9B — MERNIK Quantization
MERNIK ("the one who measures") quants of OrionLLM/OxCoder-9B (Qwen3.5-9B agentic coding finetune, 262K context): imatrix-driven priority-queue allocation, judged by all three columns in synergy — PPL (canary), KLD-vs-ref (rank), scored tasks (verdict).
Results (all builds, all columns)
HE = HumanEval, 164 tasks, pass@1. llama-server --jinja, temp 1.0 /
top_p 0.95 / top_k 20 / presence 0.0, max_tokens 2048, fixed seeds.
PPL/KLD: llama-perplexity -ngl 99 -c 1024 -n 64 -b 512 --seed 7,

OxCoder-9B-MERNIK-5100-Q4.gguf |
5.36 GB | 7.5670 | 0.0505 | 88.41% (145/164) — small beats NeoHorse big: distillate depth |
| Q6_K (stock) | 7.36 GB | 7.6758 | 0.0116 | 84.15% (138/164) — flat keeps up, allocation still wins |
Finetune-vs-finetune duel: distillate leads on all weights.
⚡ Fast ring: GPQA-recognition (non-standard). Ox-MSE-6500 49.5%, Ox-SMAPE-5100 49.0% — below Neo despite winning HE: thinkers spread first-token mass. Recognition ≠ reasoning; details in
