| # K2-Chat: a fully-reproducible large language model outperforming Llama 2 70B Chat using 35% less compute K2 Chat is finetuned from [K2-65B](https://huggingface.co/LLM360/K2). K2 Chat outperforms Llama 2-70B-Chat on all evaluations conducted. The model also outperforms Llama 3-70B-Instruct on coding tasks.
