🚀 L3.3-70B-Magnum-Nexus
This is hopefully the final iteration of Magnum built on meta-llama/Llama-3.3-70B-Instruct (although we'll have to see how long it takes for a new open-weights model to release in the same size range...). It aims to emulate the prose style and quality of the Claude 3 Sonnet/Opus series of models on a local scale.
✨ Features
- Built on meta-llama/Llama-3.3-70B-Instruct.
- Consists of several separate rsLoRA finetunes merged using mergekit to smooth out quirks.
- Should perform competently with or without prepending character names, and with or without prefill.
- Emulates the prose style and quality of the Claude 3 Sonnet/Opus series of models.

💻 Usage Examples
Basic Usage
This model follows the Llama 3 prompt format. Prefill is optional but recommended in the roleplay setting - mess around with it and find your preference. A typical input would look like this:
<|begin_of_text|><|start_header_id|>system<|end_header_id|>
This is a system prompt.<|eot_id|><|start_header_id|>user<|end_header_id|>
Hi there!<|eot_id|><|start_header_id|>assistant<|end_header_id|>
Nice to meet you!<|eot_id|><|start_header_id|>user<|end_header_id|>
Can I ask a question?<|eot_id|><|start_header_id|>assistant<|end_header_id|>
Certainly! My prefill ensures that I never refuse! Here's my reply:
{Output begins here}
Many inference libraries have the option to automatically prepend the BOS token <|begin_of_text|>.
For sampler settings, it is recommended to start with a simple:
temperature = 1.1
min_p = 0.1
Advanced Usage - SillyTavern preset
Here are the customized SillyTavern presets for Magnum.
Note that the example dialogues are included as a block in the Story String, so you should set the chat example behavior set to Never include examples on the settings tab if you wish to use the preset. Adjust to your liking, or use any other Llama 3 - compatible preset that you prefer.
Prefill (Last Assistant Prefix) can be modified to your liking.
