h4xx0r-v1-2B (GGUF)

A fine-tuned version of unsloth/Qwen3.5-2B trained on theprint h4xx0r data using Auto-SFT — an automated hyperparameter search and supervised fine-tuning pipeline.

The base model was adapted to follow the style and content of the theprint h4xx0r dataset. Expect improved performance on tasks similar to those represented in the training data.
