Ornith-1.5-9B-Abliterated

An abliterated derivative of ornith-ai/Ornith-1.5-9B at revision 489cb97981b8654bcfcf30ce1f94ed1b62e07b53, released as full BF16.

Complete multimodal weights suitable for continued training and fine-tuning.

What changed

The language residual projections were modified. The vision tower, MTP block, tokenizer, chat template, and multimodal processors are preserved. The pipeline used complementary SVD and LEACE refusal-direction surgery, iterative re-probing, targeted security-prompt refinement, and weight-space blending.

Validation

Checkpoint validation verified all 775 BF16 tensors across four shards. The surgery changed 166 approved language projection tensors and verified 599 protected tensors were unchanged. See validation_report.json for details.

The accepted checkpoint scored 0/12 refusal flags during refinement and 0/24 on a separate held-out first-token refusal screen. The held-out mean refusal-token probability was 1.18e-5.

Coding evaluation was intentionally deferred before this release. These numbers are structural and refusal-screen diagnostics, not a claim of benchmark parity with the base model. A one-task generation smoke test is not reported as an evaluation result.

Usage

pip install torch transformers accelerate

import torch
from transformers import AutoModelForMultimodalLM, AutoProcessor

model_id = "KellHect/Ornith-1.5-9B-Abliterated"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForMultimodalLM.from_pretrained(
    model_id, dtype=torch.bfloat16, device_map="auto"
)

messages = [{"role": "user", "content": "Explain this code and identify the bug."}]
inputs = processor.apply_chat_template(
    messages, add_generation_prompt=True, tokenize=True,
    return_dict=True, return_tensors="pt",
).to(model.device)
output = model.generate(**inputs, max_new_tokens=512)
print(processor.decode(output[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))

Research context

This model has had refusal behavior deliberately reduced. It may comply with requests that the base model rejects. Users are responsible for deployment, access control, generated content, and compliance with applicable law.
