+- **Developed by:** huihui-ai
+- **License:** apache-2.0
+- **Finetuned from model :** huihui-ai/gemma-3-1b-it-abliterated(https://huggingface.co/huihui-ai/gemma-3-1b-it-abliterated)
+
+This gemma3_text model was trained 2x faster with [Unsloth](https://github.com/unslothai/unsloth) and Huggingface's TRL library.
