+# Jet-Long Evaluation Datasets
+
+This repository contains the evaluation data used in the paper [Jet-Long: Efficient Long-Context Extension with Dynamic Bifocal RoPE](https://huggingface.co/papers/2607.07740). 
+
+- **Code:** [GitHub Repository](https://github.com/jet-ai-projects/jet-long)
+
+## Dataset Description
+
+These datasets are processed versions of standard benchmarks used to evaluate the long-context capabilities of Jet-Long:
+- **RULER-500**: A dataset for evaluating long-context understanding and retrieval up to 128K context.
+- **PG-19-subsample**: A subsampled version of the PG-19 dataset used for evaluating long-context language modeling and perplexity.
