Llama-Nephilim-Metamorphosis-v2-8B
This repo contains a merge of pre-trained language models created using mergekit.
A coherent Llama 3 model (composed of fine-tunes based on Instruct) was merged at low weight into a Llama 3.1 Instruct model. No fine-tuning was performed afterward. The resulting model is mostly coherent for direct chat and text generation, retaining long context capability of 3.1. A gradient merge was used at the ends and the the embed_tokens and lm_head layers retained from 3.1, which should better preserve handling of context above 8K tokens.
Testing has been performed out to 16K context, using temperature 1 and minP 0.01. Safety remains mostly intact.
Built with Llama.
