**Run the same task on multiple agents at once and see cost, time, and tokens side by side.**

Comparisons let you evaluate agents in parallel. All agents start at the same time and finish independently. A result table appears when every agent is done.

1. In the composer, click "+" and choose "Compare agents" (on Mac, "Compare Agents"), or choose "Compare with another agent" in the agent picker.
2. Pick the second agent. To add more, use "+ Add agent" (web) or the Compare chooser (Mac), which appear once a comparison has started.
3. Send the task. All agents run at once.
4. View the result page when all finish.

Where: Web and Mac composer — "+" menu › Compare agents.

Good to know: comparisons support up to eight agents. You can rename a comparison from the result page header. Related: [Read comparison results](https://agentsky.dev/help/comparison-result), [What is Agent Arena?](https://agentsky.dev/help/arena-overview).
