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

“Putting aside terms like "performance" — as they are largely used as a means of generating things "accurately" or "faster" rather than being good at stuff — Large Language Models have effectively plateaued.”

The Subprime AI Crisis, paragraph 68. The full statement is at the source.

Our reading, the sentence that was checked:

Setting aside 'performance' measures of accuracy or speed, Large Language Models have effectively plateaued.

Conditions

  • putting aside terms like 'performance' (accuracy or speed) (qualifier, stated by the speaker)

From the speaker

  • Putting aside terms like "performance"
  • "accurately" or "faster"
  • Large Language Models have effectively plateaued
  • "More powerful" never seems to mean "does more"

Our interpretation

  • This describes the state of LLM capabilities at publication, not a prediction about all subsequent development.
  • With no reporting period specified, use the latest partial calendar month before publication, September 1–16, 2024, as the contemporary observation window. Earlier models provide comparison baselines.
  • The ordinary reading is that contemporary models had stopped adding materially different useful task capabilities. Accuracy or speed improvements alone do not contradict the stated claim.
  • A new training method or product interface is not automatically a new model task capability.

Counts as supported if: Contemporaneous comparative evaluations show no material extension of useful task capabilities beyond earlier models, after excluding accuracy and speed improvements.

Counts as contradicted if: Contemporaneous demonstrations and evaluations establish that current LLMs can perform materially different useful tasks that preceding models could not perform meaningfully.

Retrospective: these criteria were written after the outcome was public.

Current assessment

Was it true for the period described?

Outcome: Unresolved

The record was checked, and the evidence available by the cutoff does not settle it.

Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale

The September evidence challenges a broad claim of stagnation: o1 introduced a different reasoning approach, and ARC Prize described improved generalization. But the claim explicitly excludes accuracy and speed, and the retrieved evaluations largely measure success on existing tasks. They do not cleanly settle whether useful task capabilities had plateaued under that narrower reading. Later releases cannot decide this historical observation.

Limitations

  • The distinction between a new capability and better execution is consequential and unstated.
  • The selected observation window is an evaluator interpretation.
  • The search does not establish an exhaustive inventory of contemporary demonstrations.

Evidence (2 items)

  • Context only: OpenAI,

    perform complex reasoning

    Why it matters here: The announcement describes a different reasoning approach and substantial results on math, coding and science evaluations. Much of the evidence measures success rates on existing task categories, which the claim expressly distinguishes from doing new things.

  • Context only: ARC Prize,

    greater generalization

    Why it matters here: The evaluators identified improved adaptation to novelty, which challenges a broad claim of stagnation. Their measured results also placed o1-preview near Claude 3.5 Sonnet on this benchmark, leaving the narrower claim about materially different useful tasks unsettled.

What would settle it

Comparative evidence about models available by publication showing materially new useful task abilities, or a broad evaluation establishing their absence under an explicit capability definition.
