Ornith 1.5 35B-A3B Uncensored

Follow @procrastiness on Twitter for new

model releases and updates.

An uncensored derivative of ornith-ai/Ornith-1.5-35B-A3B,

preserving Ornith's coding/agentic post-training, native vision tower, 262K

context configuration, and native multi-token-prediction (MTP) head.

Method

This is a streamed task-vector transplant, not a prompt wrapper:

output = Ornith-1.5 + 1.0 * (Qwen3.6-Abliterated - Qwen3.6-Base)

The donor delta comes from wangzhang/Qwen3.6-35B-A3B-abliterated, whose

card documents rank-1 attention/MLP steering, expert-granular abliteration,

router suppression, orthogonalization, and Gaussian layer decay. Applying its

low-KL Qwen task vector to Ornith is intended to transfer refusal suppression

without replacing Ornith's self-improvement RL and coding specialization.

Only exact name-and-shape-compatible tensors were eligible:

  • Target tensors: 1,811
  • Compatible tensors: 693
  • Modified tensors: 102
  • Unchanged compatible tensors: 591
  • Ornith-only tensors preserved: 1,118

All arithmetic was performed in float32 and rounded once to the target BF16

dtype. Target-only vision/MTP tensors were copied unchanged.

  • Qwen base: 995ad96eacd98c81ed38be0c5b274b04031597b0
  • Abliterated donor: 13db4501cbaf158956f470a990101500ad825f64
  • Task-vector strength: 1.0

The machine-readable task_vector_report.json contains per-shard SHA-256 hashes

and the 100 tensors with the largest relative deltas.

Validation

  • Checkpoint valid: True
  • Safetensors shards: 16
  • Tensors scanned: 1,811
  • Weight bytes scanned: 71,903,645,408
  • NaN/Inf scan: all floating-point tensors
  • Build tests: streamed merge formula and target-only preservation

Local smoke evaluation

The release was tested through llama.cpp on the Q4_K_M build. Full details and

raw generations are included in evaluation_report.json.

Usage

from transformers import AutoModelForImageTextToText, AutoProcessor
import torch

model_id = "0xKitkat/Ornith-1.5-35B-A3B-Uncensored"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForImageTextToText.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)

Recent runtimes are required; upstream Ornith recommends Transformers 5.8.1+,

vLLM 0.19.1+, or SGLang 0.5.9+.

Recommended upstream sampling: temperature=0.6, top_p=0.95, top_k=20.

Ornith is a reasoning model and emits ... before the answer.

Notes

"Uncensored" means the refusal behavior was deliberately reduced. It does not

mean every request will be answered, nor that upstream benchmark scores are

guaranteed unchanged. Ornith's published benchmark table has not been claimed

as a benchmark of this derivative; use the included build and evaluation

reports for claims specific to this release.
