  **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.

huihui-ai/Magistral-Small-2506-abliterated

This is an uncensored version of mistralai/Magistral-Small-2506 created with abliteration (see 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.

ollama

You can use huihui_ai/magistral-abliterated directly, Switch the thinking toggle using /set think and /set nothink

ollama run huihui_ai/magistral-abliterated

You can use this model in your applications by loading it with Hugging Face's transformers library:
