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

“Although GPT-4 is clearly better than GPT-3 and 3.5, it is not so far as I can tell, qualitatively better, only quantitatively better; as noted above, the limits remain more or less the same.”

GPT-4’s successes, and GPT-4’s failures, paragraph 6. The full statement is at the source.

Our reading, the sentence that was checked:

So far as Marcus can tell, GPT-4, though clearly better than GPT-3 and 3.5, is only quantitatively and not qualitatively better, and its limits remain more or less the same.

Conditions

  • so far as I can tell (qualifier, stated by the speaker)

From the speaker

  • clearly better than GPT-3 and 3.5
  • not so far as I can tell, qualitatively better
  • only quantitatively better
  • the limits remain more or less the same

Our interpretation

  • The statement combines a checkable observation about retained limitations with a qualified judgment about the kind of improvement.
  • No ordinary, unambiguous test distinguishes quantitative from qualitative improvement across the capabilities discussed.
  • Treating any surviving limitation as proof that no qualitative improvement occurred would strengthen the statement beyond what the evidence can establish.
  • Marcus acknowledges vision in the supplied context, so image input alone should not be treated as an automatic contradiction.

This claim is not graded on evidence. The record checks that the words are quoted correctly and attributed to the right person, and that the claim is classified correctly.

Current assessment

Not graded on evidence

Outcome: Can’t be checked

The statement is a recommendation, a value judgment, or too open to test. It is recorded, not scored.

Rationale

The persistence of specific limitations is checkable, but it cannot by itself settle whether improvement was qualitative. Marcus qualifies that judgment and gives no test separating the categories. The visual application is relevant contrary context, yet he already acknowledges vision. Scoring the complete statement would require imposing a disputed definition.

Limitations

  • This does not reject the checkability of narrower claims about particular limitations or benchmark improvements.
  • The visual-assistant announcement is not a matched comparative evaluation.

Evidence (1 item)

No outcome evidence: a claim of this kind is recorded and attributed, not scored.

What would settle it

A definition of qualitative improvement tied to specified capabilities and comparison tests would make a narrower claim adjudicable.
