 ## Model Description
 
-This is a random baseline model for the Frugal AI Challenge 2024, specifically for the text classification task of identifying climate disinformation. The model serves as a performance floor, randomly assigning labels to text inputs without any learning.
+This model is a fine-tuned version of answerdotai/ModernBERT-base on the Tonic/climate-guard-toxic-agent dataset. It achieves the following results on the evaluation set:
+
+Loss: 4.9405
+Accuracy: 0.4774
+F1: 0.4600
+Precision: 0.6228
+Recall: 0.4774
+F1 0 Not Relevant: 0.5064
+F1 1 Not Happening: 0.6036
+F1 2 Not Human: 0.3804
+F1 3 Not Bad: 0.4901
+F1 4 Solutions Harmful Unnecessary: 0.3382
+F1 5 Science Is Unreliable: 0.4126
+F1 6 Proponents Biased: 0.4433
+F1 7 Fossil Fuels Needed: 0.4752
