# Parameters

The Parameters page can be accessed through the side menu.

Create new system parameters to change Syntphony CAI’s behavior. A Parameter is a value that is added to configure software behavior. Insert any value to change how Syntphony CAI behaves.

The NLP confidence score module is not displayed for virtual agents integrated with LLM.

### NLP Confidence Score

In a NLP, this is a minimum level of certainty that an intent corresponds to what a user is saying. If the **minimum confidence score** is below the value set, a Not Expected answer (idk) is delivered.&#x20;

Adjusting this threshold can impact the precision and recall of the model's predictions. You can set the value by moving the bar or typing a value. [Learn more about Syntphony NLP](https://docs.conversational-ai.syntphony.com/eva-nlp/faqs-eva-nlp/)

### Request Timeout

Amount of time the virtual agent should wait for a response from OpenAI. You can set a value in seconds to configure your agent's behavior. If the request time exceeds the defined period:

* **Gen AI cell:** The flow will be halted.
* **Knowledge:** The system will trigger the Not Expected flow.
* **Rephrase Answer:** The system will deliver a static answer.
* **Zero-Shot**: System delivers fallback measures depending on where the user is in the conversation. [See them here](/user-guide/zero-shot-llm.md#request-timeout).

**The Zero-Shot module is only visible in agents integrated with OpenAI models**
{% endhint %}

### Tokens Limit

Zero-Shot models are highly influenced by the limitation of tokens: When the configured limit is reached, the system disables the functions of importing and/or creating new intents.&#x20;

### Custom Parameters

To create a custom Parameter, click on “Create parameter”. Then, a card will appear. Insert the parameter key, value, and a description, if that's the case. Click “save”. You can enable and disable a parameter any time.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.conversational-ai.syntphony.com/user-guide/configurations/parameters.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
