+# huihui-ai/Huihui-Qwen3-14B-abliterated-v2
+
+
+This is an uncensored version of [Qwen/Qwen3-14B](https://huggingface.co/Qwen/Qwen3-14B) created with abliteration (see [remove-refusals-with-transformers](https://github.com/Sumandora/remove-refusals-with-transformers) to know more about it).
+This is a crude, proof-of-concept implementation to remove refusals from an LLM model without using TransformerLens. 
+
+Ablation was performed using a new and faster method, which yields better results.
+
+**Important Note** This version is an improvement over the previous one [huihui-ai/Qwen3-14B-abliterated](https://huggingface.co/huihui-ai/Qwen3-14B-abliterated). The ollama version has also been modified.
+
+Changed the candidate layer to eliminate the problem of garbled codes
+
+## ollama
+
+You can use [huihui_ai/qwen3-abliterated:14b-v2](https://ollama.com/huihui_ai/qwen3-abliterated:14b-v2) directly, Switch the thinking toggle using /set think and /set nothink
+```
+ollama run huihui_ai/qwen3-abliterated:14b-v2

+### Usage Warnings
+
+
+ - **Risk of Sensitive or Controversial Outputs**: This model’s safety filtering has been significantly reduced, potentially generating sensitive, controversial, or inappropriate content. Users should exercise caution and rigorously review generated outputs.
+
+ - **Not Suitable for All Audiences**: Due to limited content filtering, the model’s outputs may be inappropriate for public settings, underage users, or applications requiring high security.
+
+ - **Legal and Ethical Responsibilities**: Users must ensure their usage complies with local laws and ethical standards. Generated content may carry legal or ethical risks, and users are solely responsible for any consequences.
+
+ - **Research and Experimental Use**: It is recommended to use this model for research, testing, or controlled environments, avoiding direct use in production or public-facing commercial applications.
+
+ - **Monitoring and Review Recommendations**: Users are strongly advised to monitor model outputs in real-time and conduct manual reviews when necessary to prevent the dissemination of inappropriate content.
+
+ - **No Default Safety Guarantees**: Unlike standard models, this model has not undergone rigorous safety optimization. huihui.ai bears no responsibility for any consequences arising from its use.
