# InternChatCompletionRequest

An OpenAI-compatible streaming chat completion request for one intern. Other OpenAI fields such as `temperature` or `tools` are ignored. The intern owns its sampling and its tools.

## Example Usage

```typescript theme={null}
import { InternChatCompletionRequest } from "@openrouter/sdk/models";

let value: InternChatCompletionRequest = {
  messages: [
    {
      content: "Summarize the open pull requests.",
      role: "user",
    },
  ],
  stream: true,
};
```

| `approvalMode` | [models.InternApprovalMode](../models/internapprovalmode.mdx) | :heavy\_minus\_sign: | How the run started by this prompt handles tool approvals. `self-drive` (the default when omitted) consents on your behalf and runs the shell unsandboxed. `manual` asks you before an approval-bearing tool runs, as an `openrouter.provide_input` permission request, and keeps the shell sandboxed until an escalation is allowed. The mode applies to the run this prompt starts and is not remembered by the session. Repeat it on each new prompt that should use it. A `tool` reply continues the run under the mode it started with.                                                                                           | manual            |

A last `tool` message answers the interaction named by its `tool_call_id` and requires `session_id`.                                                                                                                                                                                                                                                                                                                                                                                                                                              |                   |

The intern runs the model configured on it (`PATCH` the intern to change it). Streamed chunks report the runtime's identifier for that model as the intern reports it, or `openrouter/intern` on chunks whose event carries no model (before the intern reports one, and on the chunks the API emits itself: the timeout, run-ended and severed-stream error chunks, the stop chunk of a replay that ends without a terminal daemon event, and the final usage chunk after any of them). A usage chunk that follows a daemon completion event carries the model the intern reported. | openrouter/intern |

Omit it to start a new session. An id the intern has not seen before is not an error: it starts a new session under that id, so a mistyped id forks the conversation.
