I have no idea what I’m doing… if this causes the apocalypse someone please let me know.

magnum-v4-72b 8.0bpw h8 EXL2

Anthracite did post 8bpw quants, but they used 6-bit heads. I’m probably not doing 123b, my wallet still has PTSD from the big mixtrals…

Includes measurement.json file for further quantization

Original Model: https://huggingface.co/anthracite-org/magnum-v4-72b

Original Model Card

This is a series of models designed to replicate the prose quality of the Claude 3 models, specifically Sonnet and Opus.

experimental because trained on top of instruct; but turned out amazing; hence code named magnum-alter, the original model that kickstarted the v4 family

This model is fine-tuned on top of Qwen2.5-72B-Instruct.

Prompting

A typical input would look like this:

<|im_start|>system
system prompt<|im_end|>
<|im_start|>user
Hi there!<|im_end|>
<|im_start|>assistant
Nice to meet you!<|im_end|>
<|im_start|>user
Can I ask a question?<|im_end|>
<|im_start|>assistant
