Supported ProvidersNEW

Sophon is bring-your-own-key: it ships with no pre-configured providers. You add the ones you want, and each provider's credentials are encrypted at rest in models.json. The tables below list every provider Sophon supports.

The id in each row is the value you set as the provider type — both in models.json (the providerType field) and in the interactive sophon models add wizard. Use these exact ids.

The model lists each provider exposes — display names, capabilities, and per-token pricing in pickers and Settings — are backed by Sophon's bundled Model Catalog, which you can extend or override with your own entries.

Cloud LLM providers

API key unless the Notes column says otherwise.

Local / self-hosted

No auth — set a base URL (a sensible default is assumed if you omit it).

OpenAI-compatible

For any endpoint that speaks the OpenAI Chat Completions format.

Subscription / CLI sign-in

These reuse an existing subscription instead of a metered API key. Per-token cost is reported as $0 because billing is flat-rate. See Subscription & CLI Sign-In for the sign-in flow.

models.json example

A single configured provider looks like this. sophon models add writes the same structure for you (and encrypts the key):

{
  "providers": [
    {
      "id": "anthropic-primary",
      "name": "Anthropic",
      "providerType": "anthropic",
      "apiKey": "sk-ant-...",
      "priority": 1,
      "isDefault": true,
      "models": [
        { "id": "claude-sonnet-4-5", "isDefault": true }
      ]
    }
  ]
}

priority orders providers for routing and failover; lower numbers are tried first. Combine multiple providers, set per-provider budgets, and control fallback in Routing, Failover & Budgets.

Reaching a provider that isn't listed

If a model isn't covered by a native provider above, two ids fill the gap:

• openrouter — one API key fronts 100+ hosted models across many vendors.
• custom-openai — point at any OpenAI-compatible base URL (self-hosted, a proxy, or a new vendor) with an optional key.

• Subscription & CLI Sign-In — use Claude Pro/Max, ChatGPT, or Copilot instead of an API key.
• Routing, Failover & Budgets — priority, fallback, and spend limits across providers.
• Configuration — add your first provider via the Dashboard or CLI.
