Editor’s verdict

Perplexity Sonar API returns search-grounded answers with inline citations, suiting assistants and research tools that need current, verifiable information; the OpenAI API guide is a general-purpose model stack for generation, reasoning, and multimodal tasks where you supply the context yourself. Choose Sonar when live web grounding and source links are central; choose OpenAI when you need broad model capabilities and full control over retrieval. Check current model availability and terms before committing.
