ExuluDefaultProviders

ExuluDefaultProviders is a nested object containing ready-made ExuluProvider instances for the most commonly used models. Each entry is a fully configured provider that you can pass directly to ExuluApp.create() or reference when building an agent’s model list in the platform UI. The accessor path matches the provider key in the docs: ExuluDefaultProviders.<vendor>.<accessor>.

Example

import { ExuluApp, ExuluContext, ExuluDefaultProviders } from "@exulu/backend";

const app = new ExuluApp();

await app.create({
  providers: [
    ExuluDefaultProviders.anthropic.sonnet45,
    ExuluDefaultProviders.openai.gpt41,
    ExuluDefaultProviders.google.vertexGemini25Flash,
  ],
  contexts: [productContext],
  config: { /* ... */ },
});

Notes

Each default provider has a stable id (e.g. claude_sonnet_4_5_provider) that IMP stores in the database when a user selects it. Do not change the id without a migration.
You can mix default providers with custom ExuluProvider instances in the same array.
Model IDs in this table reflect the source at the time of the installed @exulu/backend version. Check the platform’s model admin page for live availability.
