Frequently Asked Questions

What is an AI playground?

An AI playground is a platform where you can experiment with multiple AI models, test prompts, and compare responses. Our free AI model comparison tool gives you access to 300+ models through OpenRouter integration.

How do I compare AI models?

Simply select different models in our split-view interface, enter your prompt, and see side-by-side comparisons. You can compare GPT-4, Claude, Gemini, and hundreds of other models with custom system messages and parameters.

What are temperature and top-p in AI?

Temperature controls randomness in AI responses (0=deterministic, 2=creative), while top-p controls vocabulary diversity. Our AI parameter tuning platform lets you adjust both in real-time to see how they affect outputs.
