Catch-all/Other Intent

The other intent is unique. It acts as a catch-all intent for cases where no other intent can be matched.

Using the other intent could look something like this:

import { createUI2 } from "ui2-sdk";
import { cerebras } from "@ai-sdk/cerebras";
import { z } from "zod";
 
let { identifyIntent } = createUI2({
	model: cerebras("llama-3.3-70b"),
})
	.addIntent("sum", {
		parameters: z.object({
			a: z.number(),
			b: z.number(),
		}),
		description: "Add two numbers together",
		onIntent: (intentCall) => {
			console.log(
				`${intentCall.parameters.a} + ${intentCall.parameters.b} = ${
					intentCall.parameters.a + intentCall.parameters.b
				}`
			);
		},
	})
	.addOther({
		description: "Use this for any other mathematical operation",
		onIntent: (intentCall) => console.log("That operation has no intent!"),
	});
 
identifyIntent("what is log base 2 of 4?");

This intent is rarely called, but you can instruct the AI to do so more commonly or less commonly in the description of this method.

The other Intent Lifecycle

Furthermore, the lifecycle of other is slightly different than normal intents. Specifically, because the other intent does not have any parameters, the following will occur onIntent only occurs when the intents identified goes from anything that is not other to other. In other words, even if the content of the input changes, and it was other before and after, onIntent will not be called again.

Parameters

Besides that, addOther functions very similarly to addIntent with a few "missing" parameters that you cannot customize on other.

For one, you cannot pass in a name.

Furthermore, in the configuration, you can only pass in:

• description
• onIntent
• onCleanup
• onSubmit (with React hook)

The signature of these callbacks are identical.

Recommended Use Case

It is highly recommended that for complicated applications, that you connect some form of a Chatbot/Agent onto UI2 when the other intent is submitted.

This way, the user can express complicated workflows in the UI2 input and have them ran.
