# Conversation

> TypeScript SDK reference

Defined in: [src/genai/conversation.ts:72](https://github.com/wandb/weave/blob/8c5f077eb11c42b84000726ff20504abc728d3fb/sdks/node/src/genai/conversation.ts#L72)

A Conversation groups Turns under a single `gen_ai.conversation.id`. It is
not itself an OTel span — children stamp the conversation id onto theirs.

### startTurn()

> **startTurn**(`opts?`): [`Turn`](./turn)

Start a new `Turn` under this `Conversation`. The turn inherits the
conversation's `conversationId`; `agentName`, `agentId`, `agentDescription`,
`agentVersion` and `model` fall back to the conversation's values when not
provided on `opts`.

#### Parameters

##### opts?

[`TurnInit`](./turninit) = `{}`

#### Returns

[`Turn`](./turn)

#### Examples

```ts twoslash theme={null}
// @noErrors
const turn = conversation.startTurn();
```

```ts twoslash theme={null}
// @noErrors
const turn = conversation.startTurn({
  model: 'gpt-4o',
  agentName: 'research-bot',
  agentId: 'research-bot-prod',
  agentDescription: 'Looks up facts on Wikipedia.',
  agentVersion: '1.4.2',
  userMessage: 'What is the weather in Tokyo?',
  systemInstructions: ['You are a helpful weather bot.'],
  startTime: new Date('2026-05-29T10:00:00.000Z'),
});
