How Prompt Compare works
A straightforward lab session — pick platforms, write once, compare live.
- 01
Write one prompt
Start with your question or task (up to 4,800 characters). You set up everything first — you only pay when you run the live comparison.
- 02
Choose your AI platforms
Pick 2–6 models across OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral, Perplexity, Cohere, Alibaba, MiniMax, ByteDance, Moonshot, Meta, and more — including frontier options like Fable 5.
- 03

Good to know
Results are generated through model APIs. Consumer chat products may use additional tools, memory, browsing, product instructions, or settings.
Consumer chat apps may add memory, browsing, or UI features that API results do not include. Prompt Compare shows what each model returns through its API for the same prompt — a fair apples-to-apples snapshot.
