# Jan

Connect Jan to RunAPI with a custom OpenAI-compatible provider. Create a
standard RunAPI API key in the [Authentication
Guide](https://runapi.ai/docs/guides/authentication.md) before continuing.

## Install Jan

Download and install the desktop application from the [official Jan
website][1], then open its settings.



[1]: https://jan.ai/

## Add the RunAPI provider

1.  Open **Settings -> Model Providers -> Add Provider**.
2.  Set the API format to **OpenAI-compatible** and the provider name to
    `RunAPI`.
3.  Set the Base URL to `https://runapi.ai/v1`, enter your RunAPI API
    key, and create the provider.
4.  Select a discovered model or add an exact identifier from the [Model
    Catalog](https://runapi.ai/models) in the provider's **Models** area.

The selected API format is OpenAI-compatible, so this Base URL includes
`/v1`. A provider using another public protocol must use that protocol's
own client configuration instead.

When the provider is saved, Jan requests `{base_url}/models`, which
resolves to `https://runapi.ai/v1/models`. If the model you need is not
returned, use the manual **+** action instead of changing the Base URL.

## Configure model capabilities

Jan does not infer every capability for a custom provider. Enable only
the vision, tools, or audio behavior that the selected model declares in
the [Model Catalog](https://runapi.ai/models). A UI switch cannot add an unsupported API
capability.

## Verify the connection

Start a new chat, select the RunAPI model, and send `Reply with the word
connected.` A normal complete or streamed response confirms the provider
and model are active.

## Troubleshoot

* **Every request returns `404`:** make sure the Base URL includes
  `/v1`; Jan appends the operation path.
* **No models appear:** confirm the Base URL is `https://runapi.ai/v1`,
  then add the exact model identifier manually.
* **Provider creation returns `401` or `403`:** replace the key with a
  valid standard RunAPI API key, not a Management Key.
* **Capability controls do not match the model:** configure each custom
  model from its declared capabilities rather than relying on automatic
  detection.
* **A fallback key is not tried:** Jan rotates keys for `401`, `403`, or
  `429`; other errors do not trigger key rotation.

For shared protocol behavior, use the [LLM API
Quickstart](https://runapi.ai/docs/guides/llm-api/quickstart.md). For request and response
fields, use the [Chat Completions API
Reference](https://runapi.ai/docs/api/openai/chat-completions.md).
