# CopilotKit Intelligence Mode
Intelligence currently ships as a managed cloud service. The only supported `apiUrl` /
`wsUrl` today is the CopilotKit-managed cloud Intelligence instance — the `ɵ`-prefixed
runtime internals and REST/WebSocket contract that back Intelligence are still
stabilizing and `organizationId` is reserved for future self-hosted deployments. If you
need on-prem durable threads today, use SSE mode with a persistent runner
(`SqliteAgentRunner` or a custom one) instead.
Obtain `apiKey` and `organizationId` from the CopilotKit Cloud dashboard.
### URL format
The client prepends `/api/...` and the Intelligence websocket layer derives `/runner`
or `/client` suffixes internally. Pass the bare base URLs — do NOT append `/api`,
`/socket`, `/runner`, or `/client` yourself:
```typescript
// Correct — bare base URLs
apiUrl: "https://api.copilotkit.ai",
wsUrl: "wss://api.copilotkit.ai",
// Wrong — adding /api produces /api/api/... on every REST call; /socket/runner is not a real path
apiUrl: "https://api.copilotkit.ai/api",
wsUrl: "wss://api.copilotkit.ai/socket",
```
Source: `packages/runtime/src/v2/runtime/intelligence-platform/client.ts:41-46, 259,
356-357, 437, 468, 682-708`.
## Setup
```typescript
import {
CopilotRuntime,
CopilotKitIntelligence,
createCopilotRuntimeHandler,
} from "@copilotkit/runtime/v2";
const intelligence = new CopilotKitIntelligence({
apiUrl: "https://api.copilotkit.ai",
wsUrl: "wss://api.copilotkit.ai",
apiKey: process.env.COPILOTKIT_CLOUD_API_KEY!,
organizationId: process.env.COPILOTKIT_CLOUD_ORG_ID!,
});
const runtime = new CopilotRuntime({
agents: {
/* ... */
} as any,
intelligence,
identifyUser: (request) => ({
id: request.headers.get("x-user-id") ?? "anonymous",
}),
// Optional tuning:
generateThreadNames: true, // default true — 1 LLM call per new thread
lockTtlSeconds: 20, // clamped to ≤ 3600
lockHeartbeatIntervalSeconds: 15, // clamped to ≤ 3000
});
const handler = createCopilotRuntimeHandler({
runtime,
basePath: "/api/copilotkit",
});
export default { fetch: handler };
```
When `intelligence` is set, the runtime auto-wires `IntelligenceAgentRunner` internally.
Do NOT pass `runner` — see the failure-modes section.
## Core Patterns
### Identify the user from an auth cookie
`identifyUser` is for user identification only — it does NOT forward thrown `Response`s.
`resolveIntelligenceUser` (`handlers/shared/resolve-intelligence-user.ts:14-24`) wraps the
call in try/catch and converts any thrown value (including `Response`) into a generic
`errorResponse("Failed to identify user", 500)`. Gate auth in `hooks.onRequest`
(see the `middleware` skill) and keep `identifyUser` focused on returning an id:
```typescript
import {
CopilotRuntime,
createCopilotRuntimeHandler,
} from "@copilotkit/runtime/v2";
import { parse } from "cookie";
const runtime = new CopilotRuntime({
agents,
intelligence,
// identifyUser returns the id; auth rejection is hooked elsewhere.
identifyUser: async (request) => {
const cookies = parse(request.headers.get("cookie") ?? "");
const user = await resolveSession(cookies["session"]); // your auth lib
return { id: user?.id ?? "anonymous" };
},
});
const handler = createCopilotRuntimeHandler({
runtime,
basePath: "/api/copilotkit",
hooks: {
onRequest: async ({ request }) => {
const cookies = parse(request.headers.get("cookie") ?? "");
const user = await resolveSession(cookies["session"]);
// onRequest DOES forward thrown Responses — use it for auth rejection.
if (!user) throw new Response("Unauthorized", { status: 401 });
},
},
});
async function resolveSession(token: string | undefined) {
if (!token) return null;
return { id: "user-123" };
}
```
### Disable thread-name generation to avoid a per-thread LLM call
```typescript
new CopilotRuntime({
agents,
intelligence,
identifyUser: (req) => ({ id: req.headers.get("x-user-id")! }),
generateThreadNames: false,
});
```
### Frontend — no config change
The frontend reads `GET /info` on mount. When the runtime reports `mode: "intelligence"`
and an `intelligence.wsUrl`, `CopilotKitCore` auto-switches from SSE to the websocket
transport. The React integration just points at the runtime URL:
```tsx
import { CopilotKitProvider } from "@copilotkit/react-core/v2";
export function App({ children }: { children: React.ReactNode }) {
return (
<CopilotKitProvider runtimeUrl="/api/copilotkit">
{children}
</CopilotKitProvider>
);
}
```
## Common Mistakes
### CRITICAL Missing identifyUser
Wrong:
```typescript
new CopilotRuntime({ agents, intelligence });
```
Correct:
```typescript
new CopilotRuntime({
agents,
intelligence,
identifyUser: (req) => ({ id: req.headers.get("x-user-id")! }),
});
```
`identifyUser` is required on `CopilotIntelligenceRuntimeOptions` — omitting it is a
TypeScript error and (if suppressed) crashes handlers at request time. Every thread is
scoped to a user ID.
Source: `packages/runtime/src/v2/runtime/core/runtime.ts:156-160`.
### CRITICAL Adding /api or /socket suffixes, or pointing at an unsupported self-hosted server
Wrong:
```typescript
new CopilotKitIntelligence({
apiUrl: "https://api.copilotkit.ai/api", // double /api prefix
wsUrl: "wss://api.copilotkit.ai/socket", // /socket is not a real path
apiKey,
organizationId,
});
new CopilotKitIntelligence({
apiUrl: "https://internal.myco.com/intelligence", // self-hosting is not yet supported
wsUrl: "wss://internal.myco.com/intelligence",
apiKey,
organizationId,
});
```
Correct:
```typescript
new CopilotKitIntelligence({
apiUrl: "https://api.copilotkit.ai",
wsUrl: "wss://api.copilotkit.ai",
apiKey: process.env.COPILOTKIT_CLOUD_API_KEY!,
organizationId: process.env.COPILOTKIT_CLOUD_ORG_ID!,
});
// For on-prem durability without Intelligence: SSE mode + SqliteAgentRunner.
```
Two failure modes to avoid:
1. The client prepends `/api/...` to every REST call (`#request` at line 356-357) and
the websocket layer derives `/runner` / `/client` suffixes from `wsUrl` internally.
Passing `apiUrl: ".../api"` produces double-prefixed `/api/api/threads`; passing
`wsUrl: ".../socket"` produces a broken `.../socket/runner` upgrade path.
2. Self-hosting Intelligence is not yet supported. The `ɵ`-prefixed runtime internals
and REST/WebSocket contract are still stabilizing. `organizationId` is reserved for
future self-hosted instances. For on-prem durable threads today, use SSE mode +
`SqliteAgentRunner` (see `copilotkit/agent-runners`).
Source: `packages/runtime/src/v2/runtime/intelligence-platform/client.ts:41-46, 68-69,
259, 356-357, 437, 682-708`.
### HIGH Setting runner alongside intelligence
Wrong:
```typescript
import { SqliteAgentRunner } from "@copilotkit/sqlite-runner";
new CopilotRuntime({
agents,
intelligence,
runner: new SqliteAgentRunner({ dbPath: "./threads.db" }),
});
```
Correct:
```typescript
new CopilotRuntime({
agents,
intelligence,
identifyUser,
});
```
`CopilotIntelligenceRuntimeOptions` excludes `runner` at the type level. Intelligence
forces its own `IntelligenceAgentRunner` tied to the Cloud WebSocket; a user-supplied
runner is rejected.
Source: `packages/runtime/src/v2/runtime/core/runtime.ts:149-173,285-294`.
### HIGH Calling /threads against an SSE-mode runtime
Wrong:
```typescript
// SSE-only runtime (no `intelligence` configured)
await fetch("/api/copilotkit/threads");
```
Correct:
```typescript
// Enable Intelligence mode first, OR don't call thread routes.
// Client-side, the useThreads hook errors with "Runtime URL is not configured" when
// the runtime isn't in Intelligence mode.
```
The `/threads`, `/threads/subscribe`, `PATCH /threads/:id`, `POST /threads/:id/archive`,
`DELETE /threads/:id`, and `/threads/:id/messages` routes always resolve in the router,
but the handlers call `requireIntelligenceRuntime(runtime)` first and return HTTP 422
("Missing CopilotKitIntelligence configuration. Thread operations require a
CopilotKitIntelligence instance to be provided in CopilotRuntime options.") when the
runtime isn't an `IntelligenceRuntime`.
Source: `packages/runtime/src/v2/runtime/handlers/intelligence/threads.ts:37-48`;
route table in `dev-docs/architecture/setup-intelligence.md:179-183`.
### LOW Over-clamping lockTtlSeconds
Wrong:
```typescript
new CopilotRuntime({
agents,
intelligence,
identifyUser,
lockTtlSeconds: 86400, // "I want 1-day lock"
});
```
Correct:
```typescript
new CopilotRuntime({
agents,
intelligence,
identifyUser,
lockTtlSeconds: 3600, // max is 1 hour
});
// Rethink long-running workflows if 1 hour is insufficient.
```
`lockTtlSeconds` is silently `Math.min(value, 3600)`; `lockHeartbeatIntervalSeconds` is
`Math.min(value, 3000)`. Requests over the cap are clamped without warning.
Source: `packages/runtime/src/v2/runtime/core/runtime.ts:281-307`.
### MEDIUM generateThreadNames unset expecting no LLM cost
Wrong:
```typescript
new CopilotRuntime({ agents, intelligence, identifyUser });
// assumes no extra LLM spend
```
Correct:
```typescript
new CopilotRuntime({
agents,
intelligence,
identifyUser,
generateThreadNames: false,
});
```
`generateThreadNames` defaults to `true`. Every newly created thread triggers an extra
LLM call on the Cloud side to generate a short name, billed against your Cloud quota.
Source: `packages/runtime/src/v2/runtime/core/runtime.ts` (generateThreadNames default).
