Model Comparison
The same prompt run on several models, each in its own column with its own status: streaming, finished or failed with Retry. Time, tokens and cost appear when reported, the fastest and cheapest are marked among those that reported, and a warning appears when the models ran with different settings. Pick one with Use this, rate and copy.

The decision inside it
Missing numbers are not zeros
A self-hosted model with no price says "Not reported", never $0.00, and it cannot win Cheapest. A comparison is only fair when like is compared with like, so different settings are flagged.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Model Comparison for this.
Install it: npx shadcn@latest add @layro/model-comparison
Import it from @/components/ui/model-comparison.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.
API
“Copy prompt” above puts a full brief on your clipboard — install command, dependencies, props, and the mistakes an assistant usually makes with this component.
