1.**Models** — add providers with their API keys and model lists; the credential fields are the same as in the in-app model settings. Saved models become server-side models available to all users, merged with any `AI_MODELS_CONFIG` / `ai-models.json` from your environment at request time (the panel does not modify those env files).
2.**Other sections** — access codes, generation parameters, features, observability, and quota. Saved settings are written to `data/settings.json` and apply immediately — no restart needed (a few settings such as Langfuse and DynamoDB are marked "Restart Required").
## Precedence
Settings saved in the panel override environment variables, which override built-in defaults. Removing a saved value falls back to the environment variable.
## Notes
- Secrets are stored in plaintext in `data/settings.json` (file mode 600). Keep the file private.
- On serverless platforms (Vercel, Cloudflare Workers) there is no persistent disk, so the panel is read-only — configure via environment variables there.
- With Docker, the `data/` directory is persisted via the volume in `docker-compose.yml`.
-`NEXT_PUBLIC_*` variables are baked in at build time and cannot be changed in the panel.
