Arcanum-12b: A Merged 12B Language Model

Arcanum-12b is a 12 billion parameter causal language model developed by Xclbr7. It was created through a novel merging technique, combining two existing 12B models: TheDrummer/Rocinante-12B-v1.1 and MarinaraSpaghetti/NemoMix-Unleashed-12B. This approach leverages the strengths of both parent models to create a new, distinct model.

Key Characteristics & Merging Process

• Parameter Count: Approximately 12 billion parameters.
• Architecture: Transformer-based causal language model.
• Merging Method: Utilizes the "Ties" merging technique.
• Merging Parameters: Incorporated specific density parameters for each parent model (e.g., Rocinante-12B-v1.1 with density [1, 0.8, 0.6] and weight 0.7; NemoMix-Unleashed-12B with density [0.5, 0.7, 0.9] and weight 0.8).
• Technical Details: Merging included normalization and Int8 mask, with float16 data type.

Intended Use & Considerations

Arcanum-12b is primarily intended for conversation with different personas, making it suitable for applications requiring varied conversational styles. As a merged model, it may inherit biases and limitations from its constituent models, and users should exercise caution and responsibility when deploying it.
