From the speaker
- They don’t have GPT-5
- after 14 months of trying
Our interpretation
- The claim concerns OpenAI's position on May 13, 2024.
- The plain reading of 'have' is possession of a completed GPT-5 model, including internally. Public non-release alone does not establish this.
- Fourteen months refers approximately to the interval since GPT-4's announcement. It does not establish when GPT-5 development began or whether work continued throughout that interval.
Counts as supported if: Reliable dated development records or disclosures establish that OpenAI lacked a completed GPT-5 on May 13, 2024, despite attempting to develop its successor over approximately the stated interval.
Counts as contradicted if: Reliable records establish that a completed GPT-5 existed by May 13, 2024, or establish a development chronology incompatible with the claimed duration.
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.
- Evidence as of
- Deadline state when assessed
- No horizon

- 2026-10-28.7
Rationale
The approximate interval since GPT-4's announcement is supported. The stronger assertion about OpenAI's internal possession of GPT-5 is not settled by the examined records. Treating absence of a public demonstration as proof of internal absence would assume Marcus's preceding argument rather than verify it.
Limitations
- Internal completion status may not be public.
- The claim does not define what would qualify as GPT-5.
Evidence (1 item)
Context only: OpenAI,
We’ve created GPT‑4, the latest milestone in OpenAI’s effort in scaling up deep learning.
Why it matters here: The announcement supports the approximate elapsed-time reference. It establishes neither the start of GPT-5 development nor its status on May 13, 2024.

What would settle it
Dated internal records or reliable retrospective disclosures establishing GPT-5's development and completion status on May 13, 2024.
