Overview

Manitec/Qwen3-4B-Instruct-2507-uncensored-v2 is a 4 billion parameter instruction-tuned model derived from the Qwen3 architecture. It is a minimally trained variant of Qwen3-4B-Instruct-2507, specifically designed to eliminate refusals in its responses. The model maintains a non-offensive default behavior but is capable of adhering to highly detailed and specific prompts.

Key Characteristics

  • Refusal-Free Output: Engineered to provide responses without refusals, offering greater flexibility in content generation.
  • Improved Perplexity: Demonstrates a lower perplexity (10.121119) compared to its base model (10.984474), indicating better language modeling capabilities.
  • Controlled Offensiveness: Designed to be non-offensive by default, while still allowing for adherence to detailed prompts that might explore sensitive topics.
  • Training Details: Trained for 2 epochs with a learning rate of 6e-6, using an AdamW optimizer and a cosine with restarts learning rate scheduler.

Use Cases

  • Flexible Content Generation: Ideal for applications where models typically refuse to answer, but where a controlled, non-offensive default is desired.
  • Prompt Adherence: Suitable for scenarios requiring strict adherence to detailed user instructions, even for potentially sensitive queries.
  • Research and Development: Useful for exploring the behavior of minimally censored models and their response characteristics.
