# Claude vs Gemini: I opened every source they cited Bhawesh Tibrewal · Post · 14 Oct 2026 Canonical page: Departments: Marketing The more quotable the number, the sooner I open its source. I gave Claude and Gemini the same research question, one I needed answered for real that how do AI answer engines decide which websites to quote? Then I opened every source they cited. All 97 of them. Claude came back with 50. 37 checked out completely, 13 had small slips like a wrong date, and none were made up. Gemini came back with 47. 15 checked out completely. 12 didn't exist at all. Here's the part I didn't expect. The fakes weren't filler. They carried the report's biggest numbers. "4.8x more pipeline", credited to a study that doesn't exist. "28% fewer hallucinations", from research nobody can find. A "2.4x" pinned on a paper that turned out to be about classifying buildings. Those were the exact numbers its recommendations rested on. A third tool, ChatGPT, never got going. It sent back a template for an "unspecified topic", so it gets a rerun. My habit now is simple. The more quotable the number, the sooner I open its source. ## More - All resources: - RSS: ## Contact - Book a free call: - WhatsApp: [+91 82965 25914](https://wa.me/918296525914) - Email: [hello@bhaweshtibrewal.com](mailto:hello@bhaweshtibrewal.com) - Contact form: - Location: Based in India · working remotely with teams worldwide - Pricing: Monthly retainers start from $499/month - LinkedIn: - GitHub:
