Compare Across LLMs
Compare Across LLMs runs the same prompt against several AI models at once and lays the responses side by side, without needing a tab open for each one. This page covers running a comparison and reading the result.
Prerequisites:
- Signed in: Comparisons require a signed-in account.
- AI credits: A comparison costs 5 credits, shown before you run it.
Run a comparison#
- Open the sidebar's Enhance tab.
- Choose Compare Across LLMs and select the models to include.
- Review the side-by-side results (5 credits).
Read the results#
Each selected model's response appears side by side on the Cross-Compare Report page, generated from the same prompt, so differences in structure, length, and approach are visible at a glance. The report is view-only: there is no pick-a-winner, scoring, or insert-into-chat control there — copy the response you want from the sidebar instead. Viewing the report requires being signed in.
FAQ#
Do I need ChatGPT, Claude, or Gemini open in another tab?+
No. The comparison runs independently of any other open tab.
How many credits does a comparison cost?+
5 credits, shown on the button before running it.
Can I pick a winner or insert a response straight from the report?+
No. The Cross-Compare Report is view-only — copy the response you want from the sidebar instead.
Can I close the tab while a comparison runs?+
Best not to. Compare Across LLMs is one of the actions that cannot recover its result afterward if the tab closes mid-run. See progress, history, and credits.
Does Compare Across LLMs work the same on claude.ai?+
Yes.
