 # Model Card
 
 ## 1. Model Details
-This model is the fine-tuned checkpoint described in the paper **"Not All Steps are Informative: On the Linearity of LLMs’ RLVR Training"**. It was trained using Reinforcement Learning (RL) to enhance reasoning capabilities.
+This model is a fine-tuned checkpoint described in the paper **"Not All Steps are Informative: On the Linearity of LLMs’ RLVR Training"**. It was trained using Reinforcement Learning (RL) to investigate the phenomenon of linear evolution in model weights and output log-probabilities during RLVR training.
