arXiv:2606.14971v1 Announce Type: cross Abstract: While large and diverse datasets have driven recent advances in large models, identifying the optimal data mixture for pre-training and post-training remains a significant open problem. We address this challenge with FASTMIX, a novel framework that automates data mixture discovery while training only a single proxy model. Instead of relying on predefined heuristics or resource-intensive simulations, FASTMIX jointly optimizes mixture coefficients and model parameters, substantially improving efficiency and scalability over prior approaches.

The increasing scale and complexity of large models necessitate more efficient data mixture optimization, which traditional methods struggle to provide.
Optimizing data mixtures can significantly enhance the performance and efficiency of AI models, impacting diverse applications from research to industry.
The process of discovering optimal data mixtures for training large AI models can now be significantly automated and made more efficient, reducing reliance on manual heuristics.
