“We now know that answers can even change from one month to the next—which makes third-party engineering of large language models into complex systems a huge uphill struggle. In some mission-critical cases that engineering challenge may be insuperable.”
Our reading, the sentence that was checked:
Because LLM answers can even change from one month to the next, third-party engineering of large language models into complex systems is a huge uphill struggle, and in some mission-critical cases that challenge may be insuperable.

Our interpretation
None added.
This claim is not graded on evidence. The record checks that the words are quoted correctly and attributed to the right person, and that the claim is classified correctly.
Current assessment
Not graded on evidence
Outcome: Can’t be checked
Both AI providers screened this claim on their own and found that public evidence could not settle it. It is recorded and attributed, not scored.
Why it can’t be checked
Each screen gave its own reason:
- Too vague to test: informed readers would test it in different ways and reach different answers.
- Stated as a chance or a possibility, or at medium or low confidence.
- Evidence
- Not checked
- Deadline state when assessed
- No horizon
- Assessment recorded
- Policy version
- 2026-10-28.7
Rationale
Not checked against evidence. Two independent screens, one from each provider, both found that evidence could not settle it: one found it too vague to test: informed readers would test it in different ways and reach different answers; the other found it stated as a chance or a possibility, or at medium or low confidence.
Limitations
None recorded.
Evidence (0 items)
No evidence was searched for. Both screens found that public evidence could not settle this claim.
