AI Deep Research: ChatGPT vs. Gemini vs. Perplexity Gap

There's a significant difference in "Deep Research" capabilities among AI tools like ChatGPT, Gemini, and Perplexity. While their basic answers are similar, their deep research features vary dramatically. Deep Research involves an AI agent spending minutes reading many sources to create a cited report. Perplexity Pro offers up to 20 Deep Research runs daily, totaling around 600 monthly for approximately 20 Euros. In contrast, Google's Gemini equivalent, part of the Google AI Pro plan, caps at just 5 reports per month for a similar price. This creates a 120-times difference in usage for subscribers paying nearly identical amounts. This gap matters more than simple benchmark scores, especially for those in Ireland considering a subscription. Deep Research is designed for intensive knowledge work in fields like finance, science, and engineering, providing thorough and reliable reports. This comparison helps users decide which paid AI research tool best suits their specific needs.
