Integrate GPT-5 Family Models (GPT-5, GPT-5-mini, GPT-5-nano, etc)

Please incorporate the latest GPT-5 family models.

At present, our most advanced models come from the GPT-4 family. Although they have performed well, the new GPT-5 models bring notable improvements that would enhance our AI capabilities.

From my tests, GPT-5-nano is not only stronger but also more affordable than GPT-4o-mini, for exemple.

Including the latest models that are currently absent would provide us with better options.

Thanks!
