K2: a Fully Transparent OSS Reproduction of Llama 2 Performance Using 35% Less Data
LLM360 demystifies the data recipe used for Llama 2 - 70B with K2. While K2’s performance deviates slightly from Llama’s, the scores share enough similarities to provide insight into the potential characteristics of training datasets used for Llama 2.
Evaluations

About LLM360
LLM360 is an initiative for comprehensive and fully open-sourced LLMs, where all training details, model checkpoints, intermediate results, and additional analyses are made available to the community. Our goal is to advance the field by inviting the community to deepen the understanding of LLMs together. As the first step of the project LLM360, we release all intermediate model checkpoints, our fully-prepared pre-training dataset, all source code and configurations, and training details. We are committed to continually pushing the boundaries of LLMs through this open-source effort.
