When you send your first prompt, the Arena creates a thread for the conversation and lists it in the sidebar. Every turn after that, battle or chat, is saved to the same thread with both answers, the models used, and your vote.

​
Visibility

Private

private The default. Only you can open it.

Unlisted

unlisted Anyone with the link can view it. It isn’t listed anywhere.

Public

public Anyone can view it. Meant for threads you’re happy to have reshared.

​
Share a thread

1

Open the share dialog

Open the thread and click the share button in the header.
2

Choose who can see it

Pick Unlisted or Public. Only the owner can change visibility.
3

Copy the link

Share links look like https://arena.dualmindlab.tech/share/<thread-id>. Viewers don’t need an account while public sharing is enabled.
A shared thread shows your prompts, both answers and the model names. Don’t share threads that contain anything private.

​
Access rules

Renaming, changing visibility and deleting a thread are always limited to its owner.

​
Threads from code

Pass a threadId to Start a battle or Chat to save that turn to the thread.
