🚀 JackOD-9B-Coder — a 9B merge built to FINISH agentic coding tasks. Four-way omnimerge_v2 over Qwen3.5-9B: Jack = Qwopus3.5-9B-Coder (0.30), O = Ornith-1.5-9B (0.15), D = DeltaCoder (0.55). MTP head kept.
🎯 LCB beats every source AND the base: +5.45pp over the base, +14.54pp over DeltaCoder, its heaviest.
🛑 And why. Same 55 problems, same cap, generations that NEVER terminated: DeltaCoder 25/55 · base 18/55 · Qwopus 8/55 · Ornith 2/55 · JackOD 1/55. That split is the thesis: DeltaCoder is the cohort's best coder and worst at stopping, Ornith the weakest and best at stopping. The merge takes BOTH.
🤝 tool-eval-bench hardmode, 5 seeds: JackOD 144.4 ±4.7, second behind Ornith 145.6 ±4.2, above base 142.0 — all CIs overlap. But Autonomous Planning: JackOD 5.2/6, best of five, Ornith WORST at 2.8/6. Ornith stops reliably but plans worst — it stops too early. The merge does both.
🔧 Serving: temp 0.6 / top_p 0.95 / top_k 20 + presence_penalty 1.5 — the penalty stops it re-treading a tool call. Tool calling on llama.cpp needs --jinja.
🧪 Initial impression, limited testing: fixed a cline-harness task in 535s; A3B models want 1.5-4h at <50% success.
📦 25 GGUF tiers, every K/IQ imatrix-built incl Q6_K, plus a ContribDynamic ladder (per-tensor maps from our imatrix, Unsloth-UD style).
