Melpomene 70B - Uncensored

Thalia is a chat model I have merged to provide a distillation model for future projects. Combining a Lumimaid model with Strawberry Lemonade over a heavy base of Deepseek R1 Distill Llama 70B has produced a thinking model and healed its safety alignments. This model contains the writing creativity of its two chat model parents, while adding the deep reasoning of Deepseek.

Melpomene is the same model as Thalia, abliterated via orthogonalization and reinforced via direction-only DoRA training. Use at your own risk.

In order for this model to function properly, you should prefill the opening `<think>` tag. This model's ancestry results in a hybrid thinker that sometimes chooses to think without `<think>` tags.

Merge Details

This is a merge of pre-trained language models created using mergekit.
