Qwen3.5-9B-Unredacted-MAX

Qwen3.5-9B-Unredacted-MAX is an unredacted evolution built on top of Qwen/Qwen3.5-9B . This model applies advanced refusal direction analysis and abliterated training strategies to reduce internal refusal behaviors while preserving the reasoning and instruction-following strengths of the original architecture. The result is a capable 9B parameter language model optimized for detailed responses and improved instruction adherence.

• 9B Parameter Architecture : Built on Qwen3.5-9B , offering substantially stronger reasoning capacity while remaining deployable on modern GPUs.
• Improved Instruction Adherence : Optimized to follow complex prompts with minimal unnecessary refusals.
• Efficient Deployment : Suitable for research experimentation, local inference, and AI development workflows.

Quick Start with Transformers

pip install transformers==5.3.0 (or) git+https://github.com/huggingface/transformers.git

from transformers import Qwen3_5ForConditionalGeneration, AutoProcessor
import torch

model = Qwen3_5ForConditionalGeneration.from_pretrained(
    "prithivMLmods/Qwen3.5-9B-Unredacted-MAX",
    torch_dtype="auto",
    device_map="auto"
)

processor = AutoProcessor.from_pretrained(
    "prithivMLmods/Qwen3.5-9B-Unredacted-MAX"
)

messages = [
    {
        "role": "user",
        "content": [
            {"type": "text", "text": "Explain how transformer models work in simple terms."}
        ],
    }
]

text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)

inputs = processor(
    text=[text],
    padding=True,
    return_tensors="pt"
).to("cuda")

generated_ids = model.generate(**inputs, max_new_tokens=256)

generated_ids_trimmed = [
    out_ids[len(in_ids):] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)
]

output_text = processor.batch_decode(
    generated_ids_trimmed,
    skip_special_tokens=True,
    clean_up_tokenization_spaces=False
)

print(output_text)

Intended Use

• Alignment & Refusal Research : Studying refusal behaviors and the impact of activation-level modifications.
• Red-Teaming Experiments : Evaluating robustness across adversarial or edge-case prompts.
• Local AI Deployment : Running capable instruction models on consumer GPUs or high-end GPUs.
• Research Prototyping : Rapid experimentation with transformer architectures.

Limitations & Risks

Important Note : This model intentionally reduces built-in refusal mechanisms.

• Sensitive Output Possibility : The model may generate controversial or explicit responses depending on prompts.
• User Responsibility : Outputs should be handled responsibly and within legal and ethical boundaries.
• Model Size Constraints : Although stronger than smaller variants, a 9B model still has limitations compared to very large frontier architectures.
