Llama-3-5B-Experimental

This is just an experiment similar to that done on chargoddard/llama3-42b-v0. The post-pruning was fine-tuned or "healed" with QLoRA using the code DPO dataset AlekseyKorshuk/evol-codealpaca-v1-dpo. Due to limitations, this was only trained on 3150/4935 (~64%) steps of the data. I had to restart the training about halfway through, so the logs are split in two. I am still unsure if the tokenizer is correct.

Loss: ~1.2
