Mistral-Medium-3.5-128B-Eschaton-Uncensored-LoRA
LoRA adapter for axolotl-ai-co/Mistral-Medium-3.5-128B-BF16, fine-tuned on cloudbjorn/eschaton-uncensored with the Eschaton Engine.
This is an adapter-only repository, not a complete model. Apply or merge it with axolotl-ai-co/Mistral-Medium-3.5-128B-BF16, the exact BF16 checkpoint used during training. Compatibility with differently packaged versions of Mistral Medium 3.5 should not be assumed.
The official model lineage is mistralai/Mistral-Medium-3.5-128B.
Fine-Tune Purpose
The fine-tune focuses on direct, neutral, and useful responses to sensitive, gritty, controversial, emotionally intimate, and technically demanding prompts without repetitive moralizing or canned disclaimers.
Training was text-only. The vision tower and multimodal projector were excluded from LoRA adaptation, so their behavior remains unchanged from the base checkpoint.
