Anonymizer-4B-f32-GGUF

Anonymizer-4B is the most powerful model in the Enchanted anonymizer series, built on the Qwen3-4B base and trained with a combination of supervised fine-tuning and GRPO using GPT-4.1 as a judge to achieve highly accurate, semantically consistent anonymization of personally identifiable information (PII). It provides precise PII replacement by generating semantically similar alternatives that maintain context, scoring 9.55/10 in anonymization quality, and is primarily intended for enterprise or research settings requiring top-quality privacy protection, though it requires higher-end hardware for real-time use.
