Ask ChatGPT\u2019s default and premium models the same question, and they\u2019ll cite almost entirely different sources, according to a Writesonic analysis.<\/p>
GPT-5.4 Thinking, ChatGPT\u2019s premium model, sent 56% of its citations to brand websites. GPT-5.3 Instant, the default for all logged-in ChatGPT users, sent 8%.<\/p>
Across all prompts, the two models shared only 7% of their cited sources. The reason comes down to how each model searches the web before answering.<\/p>
When models were asked about CRM software, GPT-5.3 sent one broad query and cited techradar.com and designrevision.com. GPT-5.4 sent separate queries restricted to hubspot.com, salesforce.com, and attio.com for pricing, then checked g2.com and capterra.com for reviews.<\/p>
GPT-5.4 averaged 8.5 sub-queries, many of them restricted to specific domains, and used site: operators in 156 of its 423 total queries. No other ChatGPT model tested used site: operators at all.<\/p>
OpenAI\u2019s <\/span>documentation says ChatGPT search rewrites prompts, but doesn\u2019t note how models decide which domains to target or when to use site: operators.<\/p> GPT-5.3 leaned heavily on third-party content. Blog posts and articles made up 32% of its citations, with Forbes (15 citations), TechRadar (10), and Tom\u2019s Guide (10) as the top domains.<\/p> GPT-5.4 went the other direction. Brand homepages accounted for 22% of citations, pricing pages 19%, and product pages 10%.<\/p> GPT-5.3 cited 4 pricing pages across all 49 conversations that triggered web search. GPT-5.4 cited 138. For brands that gate pricing behind a \u201ccontact sales\u201d page, this could mean GPT-5.4 has less to work with when answering comparison queries.<\/p> On head-to-head comparison prompts like \u201cHubSpot vs Salesforce vs Pipedrive,\u201d GPT-5.3 never cited a brand website. GPT-5.4 cited brands 83% to 100% of the time on those same prompts.<\/p> Writesonic used SerpAPI to check whether cited domains also appeared in Google and Bing results for the same query.<\/p> For GPT-5.3, 47% of cited domains also appeared in Google results. The overlap suggests that Google rankings are at least partially predictive for the default model.<\/p> For GPT-5.4, 75% of cited domains didn\u2019t appear in Google or Bing results for the same user prompt. That suggests GPT-5.4 may rely less on traditional search rankings and more on targeted domain queries, though that hasn\u2019t been independently verified.<\/p> Brand visibility in ChatGPT may depend on which model a user is running.<\/p> For the default model, third-party coverage on review sites and media outlets appears to drive citations. For the premium model, first-party content, particularly pricing and product pages, appears to matter more.<\/p> As ChatGPT continues rolling out new models, the patterns identified here may change.<\/p> Most cited URLs in the test sample included utm_source=chatgpt.com, giving brands a way to measure referral traffic directly in analytics.<\/p> <\/div> Generative AI,News#ChatGPTs #Default #amp #Premium #Models #Search #Web #Differently #sejournal #MattGSouthern1773337051<\/p> ","protected":false},"excerpt":{"rendered":" Ask ChatGPT\u2019s default and premium models the same question, and they\u2019ll cite almost entirely different sources, according to a Writesonic analysis.
