Description

Fix #9746

The deployment name of our o1 model is 'gpt-o1'. When adding the model, we encountered an error: "Unsupported parameter: 'max_tokens' is not supported with this model. Use 'max_completion_tokens' instead." After reviewing the code, we found that the logic checks if the model name starts with 'o1'. If the deployment name doesn't start with 'o1', the model cannot be added properly. Therefore, the logic should be changed to check if 'o1' exists anywhere in the model name instead of just at the beginning.
