Thank you for your contribution! This is a clean and necessary removal of the deprecated GPT-4.5 Preview model. The change looks good and I've verified there are no references to this model elsewhere in the codebase.

A couple of suggestions for future improvements:

1. Consider linking PRs to GitHub issues even for simple deprecation removals - this helps with documentation and tracking.
2. It might be worth adding tests for the openAiNativeModels configuration to ensure model configs remain valid after changes.

Good removal of the deprecated model. The deletion is clean and doesn't affect the surrounding model configurations.
