Assessment

Why?

Strongest counted support: OpenAI says its Navier–Stokes result used an internal model significantly more capable than GPT-6 Astra. weight 1.800000 evidence

Suppressed as dependent: The excerpt says the OpenAI team used an internal model more advanced than GPT-6 Astra.; Speaker says the OpenAI team used not GPT-6 Astra but an internal, more advanced model.

Review gaps: independence reviewed

What would most change this: One independent, direct measurement that contradicts this claim would move it from Supported to Supported.

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.

Claim edges

None. Edges are stored and displayed; v0.1 does not propagate probability across them.
