Felldude/Qwen3.5-4B-Uncensored Overview

Felldude/Qwen3.5-4B-Uncensored is a 4.5 billion parameter model built on the Qwen3.5 architecture, distinguished by its focus on generating uncensored and unfiltered responses. It leverages a unified vision-language foundation, achieving strong performance across reasoning, coding, agent tasks, and visual understanding benchmarks. The model incorporates an efficient hybrid architecture, combining Gated Delta Networks with sparse Mixture-of-Experts for high-throughput inference with minimal latency.

Key Capabilities

  • Uncensored Output: Designed to provide unfiltered results, with testing showing 98% uncensored responses when 'think mode' is off.
  • Multimodal Foundation: Features early fusion training on multimodal tokens, enabling strong performance in vision-language tasks.
  • Efficient Architecture: Utilizes Gated Delta Networks and sparse Mixture-of-Experts for optimized inference.
  • Scalable RL Generalization: Incorporates reinforcement learning across million-agent environments for robust real-world adaptability.
  • Extensive Language Support: Offers expanded coverage for 201 languages and dialects, facilitating global deployment.

Good For

  • Applications requiring uncensored or unfiltered text generation.
  • Multimodal tasks involving vision, reasoning, and coding.
  • Use cases demanding broad linguistic support across many languages and dialects.
