## 📖 OneRec-Foundation-Pretrain Models

This repository provides the pre-trained weights of the OneRec-Foundation series, which has undergone Itemic-Text Alignment and Full-Parameter Co-Pretraining.

We release this checkpoint to enable users to perform customized post-training or alignment tailored to their specific downstream tasks and datasets, providing greater flexibility for specialized research.

For technical details on the pre-training architecture, please refer to our Technical Report.
