Add support for new models (gpt-4o, o1-preview and o1-mini)

This is not an eval - it just to add support for the following new models:
gpt-4o
o1-preview
o1-mini

If your code is prone to raising errors due to undefined variables, missing models, or other issues, you might want to add more detailed error handling. Consider wrapping potential error-prone sections with try-except blocks.
