Playground FAQ
Is the AI playground free to use?
Yes. You can browse every model and set up prompts without an account, and when guest mode is enabled you get a small number of free messages per day. Signing up unlocks every model with pay-as-you-go pricing at provider cost — no credit card required.
Which AI models can I test in the playground?
200+ models across OpenAI (GPT-5, GPT-4o), Anthropic (Claude Opus, Claude Sonnet), Google (Gemini Pro, Gemini Flash), DeepSeek, Llama and more — the same curated catalog the OrcaRouter API serves, including image and video generation models.
Do I need an API key to try it?
No key is needed to browse models or, when guest mode is on, to send your first free messages. To send unlimited messages, compare models side by side, or attach images, sign in and the playground uses one of your API keys automatically.
Can I compare two AI models on the same prompt?
Yes — Compare mode fans one prompt out to up to three models side by side, streaming each answer as it arrives, so you can read them against each other before committing to a model in code.
Is the API OpenAI-compatible?
Yes. Everything you do in the playground maps to a standard OpenAI-compatible request — swap your base URL to api.orcarouter.ai/v1 and keep your existing SDK. The playground can show you the exact request payload for any conversation.
