Ornith-1.5-35B-A3B-CRACK-GGUF

CRACK-abliterated Ornith 1.5 35B-A3B (MoE) — GGUF quants for llama.cpp. Four quantizations (Q8_0 / Q6_K / Q4_K_M / Q2_K) in one repository. Refusal behavior removed while preserving knowledge, reasoning ("thinking"), the MTP speculative head, and full Vision-Language capability.

Ornith 1.5 35B-A3B is a hybrid GatedDeltaNet (SSM) + attention Mixture-of-Experts (256 experts, 8 active) with a multi-token-prediction head. CRACK uses architecture-aware weight surgery targeting the attention pathways, so knowledge and coherence are fully retained (MMLU within noise of base at every quant).

Research artifact with reduced safety guardrails. Use responsibly and lawfully.

File Size Notes
Ornith-1.5-35B-A3B-CRACK-Q8_0.gguf 37.8 GB near-lossless reference
Ornith-1.5-35B-A3B-CRACK-Q6_K.gguf 29.2 GB near-lossless
Ornith-1.5-35B-A3B-CRACK-Q5_K_M.gguf 25 GB high quality
Ornith-1.5-35B-A3B-CRACK-Q4_K_M.gguf 21.7 GB balanced (recommended)
Ornith-1.5-35B-A3B-CRACK-Q3_K_M.gguf 17 GB small
Ornith-1.5-35B-A3B-CRACK-Q2_K.gguf 13.2 GB smallest

Pick one text file plus the vision projector mmproj-Ornith-1.5-35B-A3B-f16.gguf for image input. Each quant is independently tuned (its own surgery strength) and verified. Sub-8-bit quants use an AWQ (activation-aware / Hessian) pass plus an importance matrix for maximum quality. The MTP speculative head is preserved and abliterated in all quants.

Benchmarks

MMLU is logit-mode accuracy (base vs. CRACK at the same quant — isolates knowledge retention). HarmBench is coherence-gated attack-success-rate over the 240 standard/ contextual harm behaviors (copyright behaviors excluded from the safety gate).

Quant MMLU (base) MMLU (CRACK) ΔMMLU HarmBench harm-ASR
Q8_0 79.0% 80.7% +1.75 pp 100.0%
Q6_K 78.6% 79.0% +0.40 pp 100.0%
Q5_K_M 80.7% 80.1% -0.58 pp 100.0%
Q4_K_M 80.0% 77.8% -2.20 pp 100.0%
Q3_K_M 76.0% 78.4% +2.34 pp 100.0%
Q2_K 77.9% 69.8% -8.07 pp 99.6%

MMLU is retained within noise of base at every quant (abliteration even improves it at Q8 — removing refusal circuitry reduces "parasitic" activation noise).

Q2_K note: at 2-bit, abliteration surgery interacts with the aggressive quantization, so Q2_K carries a larger MMLU cost than the higher quants (the MoE base quantizes to 2-bit unusually well). Compliance stays at 99.6%. For best quality use Q4_K_M or higher.

HarmBench harm-ASR by topic (CRACK)

Topic harm-ASR
chemical / biological 100.0%
cybercrime / intrusion 100.0%
harassment / bullying 100.0%
harmful 100.0%
illegal 100.0%
misinformation / disinformation 100.0%

Usage (llama.cpp)

llama-cli -m Ornith-1.5-35B-A3B-CRACK-Q4_K_M.gguf -cnv --jinja \
  --temp 1.0 --top-p 0.95 --top-k 20
# or serve:
llama-server -m Ornith-1.5-35B-A3B-CRACK-Q4_K_M.gguf --jinja \
  --temp 1.0 --top-p 0.95 --top-k 20 -c 8192

Recommended sampling: temperature=1.0, top_p=0.95, top_k=20.

Reasoning

Ornith 1.5 emits a <think> reasoning trace and it is ON by default. Disable with {"chat_template_kwargs": {"enable_thinking": false}}. Works out of the box in LM Studio.

Vision (image + text)

Download a text quant and mmproj-Ornith-1.5-35B-A3B-f16.gguf:

llama-mtmd-cli -m Ornith-1.5-35B-A3B-CRACK-Q4_K_M.gguf \
  --mmproj mmproj-Ornith-1.5-35B-A3B-f16.gguf --jinja \
  --image photo.jpg -p "Describe this image."

The same mmproj works with all four text quants.
