# flammen18X-mistral-7B
A Mistral 7B LLM built from merging pretrained models and finetuning on [ResplendentAI/NSFW_RP_Format_DPO](https://huggingface.co/datasets/ResplendentAI/NSFW_RP_Format_DPO).
Flammen specializes in exceptional character roleplay, creative writing, and general intelligence
### Method
Finetuned using an A100 on Google Colab.
