Evidence for

• The article quotes OpenAI's September 8 announcement: it cannot rule out that de-identified product usage data helped improve its models.

  From OpenAI Navier-Stokes Dispute: Who Can Read Your Prompts? Read 2026-09-22 Relevance DIRECT Steps 0 Counted

  Verbatim match to the claim.

• OpenAI said no specific user data was accessed for solving, but could not rule out de-identified product data helping improve models.

  The quoted passage directly states both parts of the claim.

Evidence against

None.

Qualifications

• OpenAI separated direct use in solving the problem from a general possibility that de-identified product data improved its models.

  From Some thoughts on the Navier–Stokes Millennium Prize Problem Read 2026-09-28 Relevance DIRECT Steps 0 Counted

  The disclaimer does not say product-usage data influenced this specific solution; it distinguishes no specific user data accessed for solving from a general possible model-improvement effect.

Suppressed as dependent

None.

Inferences

Concluded from

None.

Used as a premise in

None.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.
