`JsonSpec` will define the **Max value length** of the input and output of the agent. You can get the **Path** file [here](https://raw.githubusercontent.com/openai/openai-openapi/master/openapi.yaml){.internal-link target=\_blank}.

**Max value length**:

```txt
400
```

For the example, we used `OpenAI` as the LLM, but you can use any LLM that has an API. Make sure to get the API key from the LLM provider. For example, [OpenAI](https://platform.openai.com/){.internal-link target=\_blank} requires you to create an account to get your API key.

Check out the [OpenAI](https://platform.openai.com/docs/introduction/overview){.internal-link target=\_blank} documentation to learn more about the API and the options that contain in the node.
