Overview

Huihui-Qwen3-4B-Instruct-2507-abliterated is a 4 billion parameter instruction-tuned model derived from Qwen/Qwen3-4B-Instruct-2507. Its primary distinction is the application of an "abliteration" process, a technique aimed at removing refusals and significantly reducing safety filtering present in the base model. This makes it an uncensored version, intended as a proof-of-concept for refusal removal without relying on TransformerLens.

Key Characteristics

Uncensored Output: Safety filtering has been substantially reduced, allowing for a wider range of generated content.
Abliteration Technique: Utilizes a new and faster method for refusal removal, yielding improved results compared to previous implementations.
Research Focus: Developed as a crude, proof-of-concept implementation for exploring methods to remove refusals from LLMs.

Usage Warnings

Users should be aware of significant warnings associated with this model due to its reduced safety filtering:

Risk of Sensitive/Controversial Outputs: The model may generate content that is sensitive, controversial, or inappropriate.
Not Suitable for All Audiences: Outputs may be unsuitable for public settings, underage users, or applications requiring high security.
Legal and Ethical Responsibilities: Users are solely responsible for ensuring compliance with local laws and ethical standards.
Research and Experimental Use: Recommended for research, testing, or controlled environments, not for production or public-facing commercial applications.
No Default Safety Guarantees: The model has not undergone rigorous safety optimization, and huihui.ai disclaims responsibility for consequences arising from its use.
