Compare models on one prompt, no code

The which-model argument rarely survives three prompts in the playground. Free tier, in the browser.

Hi Russell,

*****************************************************
Compare models on one prompt in the browser, no code.
*****************************************************

There is one place where the entire frontier sits side by side waiting for your prompt: the OpenRouter Chat playground, in your browser. The argument about which model is best for your workload usually survives about three prompts in here.

What it is for

Race three models on one prompt

Same prompt, side by side: watch where they differ on speed, style, and how they reason.

Free tier, in the browser

No card and no code; pick a model from the dropdown and start typing.

Keep the winner

When a model earns it, its slug drops into any API call as one string. The integration can come later or never.
