Is your feature request related to a problem? Please describe.

1. Missing some SOTA models + it's cumbersome to update with the way models are handled throughout the code currently
2. Model names in UI dropdowns are a bit verbose

Describe the solution you'd like

1. Maybe piggy back off of some other library to automatically pull in models as they become available OR have a simple .json config file that models can easily be added to/removed from
2. Add human-readable names mapping (claude-3-7-... becomes Claude 3.7 Sonnet, gemini-2.5-flash-preview-04-17 becomes Gemini 2.5 Flash, etc)

Additional Context
By a similar vain it should probably allow users to use custom models more easily (holistic approach to defining model endpoints in JSON or in a single .ts file in the providers dir)
