Runtimes

Choose how the Vue primitives get their messages: the AI SDK, assistant-cloud, or your own store.

A runtime fills the threads key of AuiConfig. The AuiProvider makes its messages and actions available to Vue primitives. Choose the runtime by where conversations and messages need to live.

Runtime	Threads	Messages	Guide
`AISDKChat`	One thread	One client-side AI SDK chat	AI SDK
`AISDKThreads`	A thread list in memory	One client-side AI SDK chat per thread	AI SDK
`AISDKThreads` with `cloud`	A thread list backed by assistant-cloud	One AI SDK chat per thread, with cloud-backed history	Cloud
`RuntimeAdapter`	Supplied by your runtime	Your external store	External store

AISDKChat

AISDKChat creates one thread. Its default AssistantChatTransport sends to /api/chat.

app/components/ChatAssistant.client.vue

<script setup lang="ts">
import { AuiConfig, AuiProvider } from "@assistant-ui/vue";
import { AISDKChat } from "@assistant-ui/ai-sdk";

const config = AuiConfig({
  threads: AISDKChat(),
});
</script>

<template>
  <AuiProvider :config="config">
    <slot />
  </AuiProvider>
</template>

See AISDKChat for transport options and the server route.

AISDKThreads

AISDKThreads creates a list with one AI SDK chat per thread. Without cloud, the list and chat histories stay in memory for the lifetime of the client.

app/components/ThreadsAssistant.client.vue

<script setup lang="ts">
import { AuiConfig, AuiProvider } from "@assistant-ui/vue";
import { AISDKThreads } from "@assistant-ui/ai-sdk";

const config = AuiConfig({
  threads: AISDKThreads(),
});
</script>

<template>
  <AuiProvider :config="config">
    <slot />
  </AuiProvider>
</template>

See AISDKThreads for the runtime setup and Thread list for the controls that switch between conversations.

assistant-cloud

Pass an AssistantCloud instance as the cloud option to AISDKThreads for a remote thread list and cloud-backed message history. The Cloud guide covers setup and persistence.

External store

Use RuntimeAdapter when your own store supplies message state and actions. The External store guide shows how to connect it to AuiConfig.
