Private LLM now supports two new uncensored models based on Alibaba's Qwen3 4B Instruct 2507: Qwen3 4B Heretic and Qwen3 4B Heretic NoSlop. These models run 100% on-device with zero data collection, delivering unrestricted AI for roleplay, creative writing, and uncensored chat. Update to v1.9.11 on iPhone/iPad and v1.9.13 on Mac to try them today.

What Are Qwen3 4B Heretic Models?

The Qwen3 4B Heretic models are uncensored variants of Alibaba's Qwen3 4B Instruct 2507, created using the Heretic tool - a fully automatic censorship removal system that eliminates safety alignment without expensive fine-tuning. These models remove refusals, content restrictions, and safety filters while maintaining response quality with low KL divergence (0.43).

Two Variants Available

Qwen3 4B Heretic - The standard uncensored variant that removes all safety restrictions while preserving the base model's capabilities for roleplay, creative writing, and unrestricted conversations.

Qwen3 4B Heretic NoSlop (Exclusive) - A Private LLM exclusive variant that applies the same Heretic technique to reduce flowery, cliché-heavy writing style, also known as AI slop. This produces more direct, natural outputs without the excessive prose that many language models default to. If you're tired of AI responses that sound like purple prose, the NoSlop variant delivers refreshingly direct content. This is a custom trained model that is exclusively available only in Private LLM.

Why Choose Qwen3 4B Heretic?

Unrestricted roleplay: Create believable characters that stay in persona without content filters interrupting the experience.
Interactive fiction: Build branching stories and "choose-your-own-adventure" dialogues without refusal breaks.
NSFW chat: Explore adult themes and mature content without censorship, fully local and private.
Creative writing partner: Draft scenes, refine dialogue, and develop story arcs without moralizing interjections.
Direct outputs (NoSlop): Get natural, concise responses instead of flowery AI prose.

What Makes Heretic Different?

Traditional uncensored models often require expensive fine-tuning or hand-crafted prompt engineering to bypass restrictions. Earlier methods like abliteration use manual layer selection with human evaluation, which can degrade model quality and often requires additional DPO training to recover performance. Heretic takes a different approach - it's a fully automatic system using TPE-based optimization (via Optuna) that simultaneously minimizes both refusals and KL divergence from the base model.

This technical difference matters: Heretic achieves much better quality preservation than manual abliteration methods. For example, Gemma 3 12B processed with Heretic achieves a KL divergence of just 0.16 compared to 0.45-1.04 with traditional abliteration methods - significantly closer to the original model's behavior. Heretic also optimizes per-layer refusal direction indices with separate parameters for attention and MLP layers, producing more precise results without requiring human evaluation or expensive post-training.

What this means for you:

Lower refusal rates compared to base models
Superior response quality preservation (KL divergence typically 0.16-0.43 depending on the model)
No need for elaborate jailbreak prompts
Consistently uncensored behavior across all topics
No performance degradation that requires additional recovery training

The NoSlop variant uses the same Heretic technique as the uncensored model, but for reducing AI slop in the model's responses rather than reducing censorship. This makes it particularly useful for dialogue, roleplay responses, and practical applications where direct communication matters more than literary flourish. If you're a seasoned AI user who's wary of the AI smell in responses from apps like ChatGPT, Claude, Gemini, Grok etc, this model's responses will feel refreshingly new.
