### Changes and Optimizations.
1. **Improved Error Handling in `get_model`**.
   - Replaced the `if` statement with a `try-except` block to catch `KeyError` directly, which is more efficient than checking and then accessing the dictionary.

2. **Reduced Logger Calls in `add_model`**.
   - Moved the logger debug statements to only occur at necessary points, avoiding redundant calls.
   - Combined the final log message into one call rather than multiple scattered calls during the process.

3. **Streamlined Model Initialization in `add_model`**.
   - Pulled the model class retrieval and initialization outside the logger debug call to minimize calculation duplication, focusing on reducing lookup overhead.

By reducing the number of logger debug calls, and optimizing model checks and retrievals, the overall performance of the `add_model` method is improved.
