Llama-3-15B-Instruct-zeroed

This is a merge of pre-trained language models created using mergekit.

Merge Details

Merge Method

This model was merged using the passthrough merge method while zeroing o_proj and down_proj which led to an decrease in perplexity (good) compared to similar 15B merges. This was a recommendation from Charles Goddard - thank you for sharing the method of merging as well as Toasty Pigeon for bringing it to my attention!

Finetuned Version

A finetuned version of this model can be found at elinas/Llama-3-15B-Instruct-zeroed-ft which seems to improve performance.
