> `const` **startSession**: (`opts`) => [`Conversation`](../interfaces/conversation) = `startConversation`

<GitHubLink url="https://github.com/wandb/weave/blob/7c9efdc9fe05ffcaf2430dd652ef9bc5b3ffdfaa/sdks/node/src/genai/api.ts#L33" />

Start a new Conversation and install it as the current conversation.
Subsequent calls to `startTurn` will pick it up automatically.

Pass `attributes` to propagate custom (non-semconv) attributes to every
span the conversation emits.

## Parameters

<ParamField path="opts" type="ConversationInit = {}">
  See [`ConversationInit`](../interfaces/conversationinit).
</ParamField>

## Returns

[`Conversation`](../interfaces/conversation)

## Examples

```ts twoslash theme={null}
// @noErrors
weave.startConversation({agentName: 'research-bot'});
```

```ts twoslash theme={null}
// @noErrors
weave.startConversation({
  agentName: 'research-bot',
  conversationId: '019efa53-8a65-711c-b4c1-7c1cb72c0bb7',
  attributes: {'myagent.version': '1.23'},
});
```
