# Sessions
> Continue one conversation across multiple V4 runs.
A **session** holds the agent's conversation and can reuse its live browser.
One session ID can contain multiple runs. Every run creates a session implicitly
unless you pass an existing session ID.
Pass `session_id` / `sessionId` to continue:
```python Python theme={null}
first = client.runs.create("Open Hacker News")
client.runs.wait_for_completion(first.id)
follow_up = client.runs.create(
"Now summarize the top story",
session_id=first.session_id,
)
result = client.runs.wait_for_completion(follow_up.id)
print(result.result)
```
```typescript TypeScript theme={null}
const first = await client.runs.create({
task: "Open Hacker News",
model: "grok-4.5",
});
await client.runs.waitForCompletion(first.id);
const followUp = await client.runs.create({
task: "Now summarize the top story",
model: "grok-4.5",
sessionId: first.sessionId,
});
const result = await client.runs.waitForCompletion(followUp.id);
console.log(result.result);
```
Omit the session ID for a new conversation. Pass only a [workspace
ID](/cloud/agent/workspaces) when you want a fresh conversation that keeps the
same files.
