What you can do with it
Arena lets you compare responses from different AI models, including anonymous head-to-head battles where you vote on your preferred answer. It also provides direct model selection and public rankings. This makes it useful for comparing capabilities on your own prompts, while contributing feedback to a public model-evaluation platform.
What’s included for free
Arena's terms currently state the service is offered free of charge. Model availability and usage controls may change. Prompts and votes are collected for evaluation and may be shared with model developers.
Demos may have queues or temporarily unavailable compute.
