+  description: |
+    This model is a fine-tuned version of Qwen/Qwen2.5-7B-Instruct on the OpenThoughts2-1M dataset.
+
+    The OpenThinker2-7B model is the top 7B open-data reasoning model. It delivers performance comparable to state of the art 7B models like DeepSeek-R1-Distill-7B across a suite of tasks. This model improves upon our previous OpenThinker-7B model, which was trained on 114k examples from OpenThoughts-114k. The numbers reported in the table below are evaluated with our open-source tool Evalchemy.
