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

“We also know that OpenAI’s training and inference costs in 2024 were around $7 billion, meaning that either refining current models or building new ones is quite costly.”

Deep Impact, paragraph 95. The full statement is at the source.

Our reading, the sentence that was checked:

OpenAI's training and inference costs in 2024 were around $7 billion.

From the speaker

  • OpenAI’s training and inference costs
  • in 2024
  • were around $7 billion

Our interpretation

  • The ordinary reading is expenditure attributable to calendar 2024, not a forecast made during that year.
  • The post cites press estimates, so the accounting basis is estimate.
  • Around $7 billion allows ordinary approximation, but does not license substituting all research spending or annualized commitments for training and inference expenditure.
  • Training may include preparatory runs and related model work; the source does not precisely delimit those costs.

Counts as supported if: Reliable retrospective estimates or records place combined calendar-2024 training and inference expenditure near $7 billion on a consistent scope.

Counts as contradicted if: Reliable retrospective evidence places that same expenditure materially away from $7 billion, with uncertainty small enough to exclude ordinary approximation.

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

Contemporaneous reporting explains the $7 billion figure as expected spending. A later Epoch reconstruction reaches roughly that scale when broader research compute is included, but explicitly retains projections and an amortization assumption. This makes the figure plausible as a broad estimate without establishing the completed-year training-and-inference cost asserted in the post. The records also do not establish a sufficiently comparable contrary total.

Limitations

  • Primary financial records isolating the relevant expenses were not obtained.
  • The original report was inaccessible; its forecasts are represented through a readable secondary summary.
  • A broader reading that includes all research compute has more support, but changes the metric's scope.

Evidence (2 items)

  • Context only: DeepLearning.AI,

    $3 billion

    Why it matters here: The article reports expected training spending and separately forecasts approximately $4 billion of inference spending. These explain the roughly $7 billion figure's origin, but are not completed-year results.

  • Context only: Epoch AI,

    projections for the final quarter

    Why it matters here: Epoch reconstructs roughly $7 billion of research, training and inference compute, but its inputs include final-quarter projections and an assumed research amortization schedule. It therefore offers approximate corroboration under a broader scope, not a settled realized training-and-inference total.

What would settle it

A retrospective 2024 expense breakdown separating training, inference and other research, with consistent treatment of amortization, credits and personnel costs.
