Pernicious Prophecy 70B Overview

Pernicious Prophecy 70B, developed by Black Ink Guild (SicariusSicariiStuff and invisietch), is a 70 billion parameter model built on the Llama-3.3 architecture. It utilizes a unique two-step development process involving a merge of four high-quality Llama-3 based models, followed by a targeted SFT (Supervised Fine-Tuning) step.

Key Capabilities & Features

• Uncensored Outputs: Specifically designed to produce uncensored content, addressing refusals and positivity bias found in other models.
• Versatile Use Cases: Optimized for roleplay, general assistant tasks, and diverse applications.
• Extended Context Length: Tested and stable with a context length of up to 32,768 tokens, making it suitable for long-form interactions.
• Enhanced Storytelling: Incorporates models known for exceptional formatting, roleplay performance, and long-form storytelling capabilities.
• Prompt Sensitivity: Highly responsive to detailed system prompts, allowing for precise control over output style and content.

Development Process

The model's creation involved:

1. Merge Step: A model_stock merge combining SicariusSicariiStuff/Negative_LLAMA_70B (for low censorship and reduced bias), invisietch/L3.1-70Blivion-v0.1-rc1-70B (for formatting and intelligence), EVA-UNIT-01/EVA-LLaMA-3.33-70B-v0.1 (for varied, long-form storytelling), and aaditya/Llama3-OpenBioLLM-70B (for anatomical understanding and reasoning).
2. Finetuning Step: A qlora-based finetune on 2x NVIDIA RTX A6000 GPUs using a curated 18 million token dataset to refine the merge and address specific issues.

Recommended Settings

Users should employ the Llama-3 Instruct format. Suggested sampler settings include a Temperature of 0.9-1.1, Min P of 0.06-0.12, Repetition Penalty of 1.07-1.09, and a Repetition Penalty Range of 1,536. The model is sensitive to prompting, with specific tips provided for formatting and system prompts.
