Description

Shelley currently has three ways to configure models:

1. Config file (which allows the exe.dev gateway)
2. Environment flags
3. BYOK (Bring Your Own Key) in the UI

The goal is to consolidate model management into the BYOK UI as the primary configuration method.

Proposed Approach

Seed the database with exe.dev gateway models when building the exeuntu image, rather than relying on config files or env flags. This allows the BYOK UI to be the single source of truth for model configuration.

Notes

• There are nuances to work out in the implementation details
• This should align with the broader goal of having all model configuration manageable through the UI
