# lobotollama-368b prune [Meta-Llama-3.1-405B-Base](https://huggingface.co/meta-llama/Meta-Llama-3.1-405B).
This is a negative-merge of pre-trained language models created using [mergekit](https://github.com/cg123/mergekit).

# Just so you meow, this did not turn out all that great in the perplexity benchmarks. Needs healing, you'll probably need 32xh100 to do a full finetune.
# Model was designed to fin in a M2 mac-studio 192gb in 4bit.
