+# 🔍 ERNIE 4.5 LogProb Compare
+
+This demo compares two ERNIE 4.5 models — `baidu/ERNIE-4.5-0.3B-PT` and `baidu/ERNIE-4.5-0.3B-Base-PT` — on the same input sentence.
+
+For each token, the app displays:
+- Token-wise log probabilities
+- Top-k predicted tokens (with probability)
+- Total sentence log probability
+
+Useful for debugging, evaluation, or teaching language model internals.
