“Exhibit A: OpenAI’s CTO Mira Murati just publicly acknowledged what I long suspected: there is no mind blowing GPT-5 behind the scenes as of yet.”
Our reading, the sentence that was checked:
As of June 2024, OpenAI has no mind-blowing GPT-5 model waiting behind the scenes.

From the speaker
- OpenAI’s CTO Mira Murati just publicly acknowledged
- no mind blowing GPT-5 behind the scenes
- as of yet
Our interpretation
- Mind blowing is read ordinarily as a substantial capability advance over the models then available publicly.
- GPT-5 is treated as shorthand for the anticipated next major model; the quoted remarks address internal models generally rather than confirming an internal model name.
- The observation window is June 1–15, 2024, the current month through publication, reflecting just and as of yet.
- The claim concerns an already-existing internal capability lead, not whether a much stronger future model could be developed.
Counts as supported if: A contemporaneous on-record account from someone positioned to know says OpenAI's internal models lacked a substantial capability lead over public models.
Counts as contradicted if: Dated internal evaluations or credible on-record accounts establish that OpenAI already possessed a substantially more capable next-generation model during the target period.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Supported
The dated evidence matches what the claim committed to, under the criteria frozen before grading.
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
On the ordinary reading of a substantially stronger model already waiting internally, the contemporaneous report supports Marcus. It attributes to Murati the assessment that internal models were only modestly ahead of public ones. This supports a qualitative June capability comparison, not a precise finding about a model officially named GPT-5 or a limit on future progress.
Limitations
- The decisive source is contemporaneous news reporting because the relevant primary interview transcript could not be recovered.
- The assessment relies on the CTO's reported account, without independent access to internal evaluations.
- The result depends on the stated ordinary interpretation of mind blowing and GPT-5.
Evidence (1 item)
Supports the claim: The Decoder,
not much
Why it matters here: The contemporaneous report attributes a modest internal capability lead to OpenAI's CTO. This supports the ordinary qualitative reading, although it does not independently measure private models or identify one as GPT-5.
