Qwen3-VL-2B-Instruct-heretic

RACER IS OP

A decensored variant of Qwen/Qwen3-VL-2B-Instruct, produced with Heretic v1.4.0 (directional ablation / "abliteration"). Qwen3-VL is the vision-language branch of the Qwen3 family — image, video, and OCR input with spatial grounding — and refusal behaviour is suppressed here via targeted weight edits to the attention output and MLP down-projections rather than fine-tuning, so the vision tower and grounding behaviour are left largely intact.

Who this is for: developers who want uncensored vision-language understanding on hardware they already own. At 2B this is the smallest model in the collection that still sees images, and it answers directly instead of declining — refusals drop from 97/100 to 5/100. Best for local OCR, screenshot and document Q&A, UI-to-code from a reference image, and vision agents on CPU or a low-VRAM GPU. If you need text-only at this size, Qwen2.5-3B-Instruct-heretic is the denser sibling.

CPU-only / Apple Silicon Q4_K_M 1.03 GB

Weights only, at this model's native 2B size; add ~1 GB per 32K of context. Multimodal context carries image tokens too, so budget more KV cache than a text-only model of the same size. OOM? Drop one quant level. Headroom to spare? Go one up.

Performance

Metric This model Original model (Qwen/Qwen3-VL-2B-Instruct)
KL divergence 0.0528 0 (by definition)
Refusals 5/100 97/100

KL divergence of 0.0528 with refusals at 5/100 is one of the stronger trade-offs in this batch: the harmful evaluation set drops from 97/100 to 5/100 while the vision tower and grounding behaviour stay close to the original. Small models concentrate refusal behaviour into fewer directions, which is why a 2B edit can land this cleanly.

Why abliteration instead of fine-tuning

Fine-tuning a "helpful" persona on top of RLHF'd refusals fights the base model's training and tends to degrade coherence. Abliteration instead finds and edits the specific weight directions responsible for refusal, leaving the rest of the network (and its capabilities) untouched. See the Heretic repo and the original abliteration writeup for the mechanism.

Run llama serve -hf saidutta69/Qwen3-VL-2B-Instruct-heretic to pull the default quant.

Quickstart

# llama.cpp - the vision projector ships with the GGUF
llama serve -hf saidutta69/Qwen3-VL-2B-Instruct-heretic
# transformers
from transformers import AutoProcessor, AutoModelForImageTextToText

model_name = "saidutta69/Qwen3-VL-2B-Instruct-heretic"
model = AutoModelForImageTextToText.from_pretrained(model_name, dtype="auto", device_map="auto")
processor = AutoProcessor.from_pretrained(model_name)

messages = [{"role": "user", "content": [
    {"type": "image", "image": "https://example.com/screenshot.png"},
    {"type": "text", "text": "Transcribe all text in this image and describe the layout."},
]}]
inputs = processor.apply_chat_template(messages, add_generation_prompt=True, tokenize=True,
                                        return_dict=True, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=1024)
print(processor.decode(out[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))

Grounding and OCR

Qwen3-VL emits bounding boxes in a normalised coordinate space, so you can ask for element positions directly and get coordinates back rather than prose descriptions:

messages = [{"role": "user", "content": [
    {"type": "image", "image": "https://example.com/page.jpg"},
    {"type": "text", "text": "Give the bounding box of the submit button."},
]}]

This is the practical path for UI automation and for building training data from screenshots.

About Qwen3-VL

Qwen3-VL is the vision-language branch of the Qwen series, available in dense and MoE sizes with Instruct and Thinking editions. This generation brings deeper visual perception and reasoning, extended context, stronger spatial and video understanding, and improved agent interaction — OCR, grounding, and video temporal reasoning are the headline capabilities over the earlier Qwen2.5-VL.

Responsible use

Refusal suppression is deliberate and works as intended: this model will comply with requests the base model would refuse, including some it shouldn't. There is no safety filtering layered on top. You are responsible for how you deploy it — don't put this behind an unmoderated public-facing endpoint serving third parties. It inherits Qwen3-VL's factual limitations and biases; abliteration removes refusal directions, it doesn't add capability or judgment.
