## Add a decision model

Go to **Models + Endpoints**, open the **Add Model** tab and pick the provider, for example OpenAI. Pick the decision model under **LiteLLM Model Name(s)**, for example `gpt-6-luna`, and a **Decision model** note confirms the pick and links to the Decisions playground. Enter the provider credentials as you would for any other model, then click **Add Model**. The model then answers on `/v1/decisions` and `/v1/systemone` under its public model name. Providers that need an endpoint URL, such as Databricks and Microsoft Foundry, take it in the **API Base** field, matching the `api_base` in the [proxy setup](./index.md#proxy-setup). The optional **Mode** dropdown has a **Decisions - /v1/decisions** entry from `v1.107.0-rc.1`, named **Evaluation - /v1/decisions** in `v1.106.0`, for health checking the model over `/v1/decisions`.

## Decisions playground

The Playground **Decisions** tab (Beta) sends requests to both routes. Open it at `LITELLM_PROXY_BASE_URL/ui/?page=llm-playground&tab=system-one`, or go to **Playground** and pick **Decisions**. The **Endpoint** selector picks `/v1/decisions` (OpenAI Decisions format) or `/v1/systemone` (System One format). The **Model** selector lists the decision models in your `model_list`, such as `jev` from the [proxy setup](./index.md#proxy-setup), and a proxy with no decision models shows an **Add a decision model** link instead. An OpenAI decision model such as `luna` is listed once its `model_info` sets `mode: evaluation`.

```yaml showLineNumbers keep-model-ids
model_list:
  - model_name: luna
    litellm_params:
      model: openai/gpt-6-luna
      api_key: os.environ/OPENAI_API_KEY
    model_info:
      mode: evaluation
```

**API key** picks the key. **Current UI Session** uses your dashboard login, and **Virtual Key** attributes the call to a key you paste. **Load example** fills in one of four requests: **Triage a bug report**, **Route a support ticket**, **Moderate a forum comment** or **Score a sales lead**. The form starts empty, and the eraser button clears it. Type the text the model should read into **Input**, then give each question a **Name**, an **Answer type** and **Instructions**. The answer types are **Choice**, **Yes / no** and **Score** on `/v1/systemone`, and **Predicate**, **Choice** and **Score** on `/v1/decisions`, which also takes an optional **Safety identifier**. **Add question** adds a card, and the trash buttons remove questions, options and levels. The **cURL** tab shows the same request as a curl command that follows your edits, and **Copy cURL** copies it once the form has no issues. The form only takes text, so send image input on `/v1/decisions` with curl or the SDK.

Problems the form can catch, such as an empty **Input**, are listed above **Send**, which stays disabled until they are fixed. Others come back from the provider when you send, such as a `/v1/systemone` yes / no question with no instructions and no **Yes means** or **No means**. Once the call returns, each question shows its answer and probabilities, and the **Response** header shows the latency, the model name from the response and the token usage. **Raw response** opens the JSON body. An error, such as a 401 for a bad key, shows **Decisions request failed** and the error message instead of the answers.

The tab is in `v1.106.0` and later, and not in `v1.104.2` or `v1.105.0`. `v1.106.0` starts with the first example filled in, picks others from a dropdown instead of **Load example**, and labels the eraser **Clear**. The [TypeSafe page](../pass_through/typesafe.md#try-it-in-the-admin-ui) walks through the System One form, validation and answer view.
