Pundit ClaimsAI claims by Gary Marcus and Ed Zitron, with the evidence

“Suleyman’s colleague Kevin Scott hinted that GPT-5 would blow away PhDs, and be vastly better than GPT-4; in reality the improvements were far more modest.)”

Promises are cheap, paragraph 8.

Our reading:

GPT-5's improvements over GPT-4 were far more modest than Kevin Scott had hinted.

Why

On June 5, 2024, The Decoder reported that Kevin Scott said early looks at next-generation models suggested they could pass PhD qualifying exams. He said GPT-4-class models perform about as well as high school students on AP exams (e1). Scott added that this 'probably sounds like a bigger deal than it actually is' (e1). The report does not show him naming GPT-5. 'Blow away PhDs' is Marcus's paraphrase, not Scott's wording. On August 7, 2025, OpenAI said GPT-5 pro scored 88.4% on GPQA without tools (e2). OpenAI reported this figure itself, and the evidence gives no GPT-4 score to compare it with. The claim gives no measure for 'far more modest', and the hint it compares against is hedged and does not name a model. So the claim cannot be scored as true or false.

Caveats

  • The GPQA figure comes from OpenAI and was not independently checked.
  • The figure is for GPT-5 pro with extended reasoning, not necessarily for the standard GPT-5 model.
  • Scott's remarks are known only from a news report (e1), not from a recording or transcript in the evidence.
  • The evidence gives no GPT-4 score on the same benchmarks, so it does not show how big the improvement was.
  • The evidence does not compare GPT-5's real-world usefulness with GPT-4's.

Where we had to interpret

  • Scott's recorded June 2024 remark was that next-generation models 'could pass PhD qualifying exams', compared with GPT-4 matching high schoolers on AP exams. He also said it 'probably sounds like a bigger deal than it actually is'. He did not name GPT-5 in the coverage I read.
  • 'Blow away PhDs' is Marcus's paraphrase. 'Far more modest' has no measure. On benchmarks such as GPQA, GPT-5 scores very high, but whether the real-world gain was 'far more modest' than a hint is a judgment call.
  • There is no plain, agreed measure for comparing a hint to an outcome, so I treat this as not adjudicable.
