+# PI-LLM Dataset File List
+
+This repository hosts the **PI-LLM** dataset.  
+Currently it includes two files:
+
+- **core.parquet** → Main dataset (randomized updates). Recommended as the primary/SOTA comparison setting; All tested models fail to reliably retrieve the last value. 
+- **sequential_additional.parquet** →  Sequential mode (non-randomized, strict per-key ordered update blocks). Trivial for humans yet still challenging for many LLMs; smaller (all <600B) models are especially affected, with proactive-interference effects clearly exposed (even in short contexts, ~5–8k tokens).
