GPT and Perplexity Deep Research for real workflows
GPT is provided by OpenAI and emphasizes advanced reasoning and strong coding. Perplexity Deep Research, from Perplexity AI, emphasizes web search and cited sources. The stronger option depends on the input, output constraints, and review standard.
How to test GPT vs Perplexity Deep Research
Run the same prompt, source context, output format, and acceptance criteria through both models. Score accuracy, instruction following, edit time, latency, and current cost separately. Repeat the test on several representative tasks before standardizing on either model.
