Perplexity AI is better for real-time search, verified facts, and quick summaries of multiple sources. ChatGPT (GPT-5.2) is better for reasoning, writing, coding, creativity, and multimodal tasks. Use Perplexity when you need fast, source-based answers; use ChatGPT when you need deeper explanations, structured content, or complex problem-solving.
Many Perplexity users find that relying on a single AI tool can’t meet all their workflow needs. Many also want to use top models like GPT-5.2 and Gemini 3 Pro side by side for comparison and deeper research.
GlobalGPT solves this problem. It gives you access to 100+ top AI models—Perplexity, GPT-5.2, Claude Sonnet 4.5, Gemini 3 Pro,Sora 2 Pro and Nano Banana Pro—all in one place, so you don’t need multiple subscriptions to cover your workflow. It spans the full AI workflow, from chat and research to image and video generation, and with a basic plan around $5.8, it’s one of the cheapest ways to access a multi-model toolkit.
