From the model leaderboards section of the model catalog, you can [browse leaderboards](https://aka.ms/model-leaderboards) to compare available models as follows:
 
 - **Quality, cost, and performance leaderboards** to quickly identify the model leaders along a single metric (quality, cost, or throughput);
 - **Trade-off charts** to see how models perform on one metric versus another, such as quality versus cost;
