[Wolfram|Alpha](https://www.wolframalpha.com/about) offers expert, real-time, verifiable answers for knowledge queries and supports natural language queries.

You can submit inline queries to fetch factual figures, and solve one line problems.

#### Querying Wolfram|Alpha

Type your query followed by = ?

```
distance to the moon = ?
```

After a moment an answer from Wolfram|Alpha will be inserted:

```
distance to the moon = 365,519 kilometers
```

{% hint style="warning" %}
Wolfram|Alpha supports only queries in English at this time.
{% endhint %}

#### Fall back on OpenAI models

If Wolfram|Alpha does not have an answer for your query (for instance, if your query was not expressed in English), knowledge assistant will fall back to the latest model from OpenAI instead.

The OpenAI's large language model we use may "hallucinate" factually incorrect information and cannot obtain real-time information from the internet.
