Jev + fallback vs. GPT-5.6 Luna on passage support

The claim

Same accuracy as GPT-5.6 Luna and faster, but the fallback route cost more overall.

Our read

Reporting a downside is a credibility signal. A useful reminder that a cascade only saves money when the fallback fires rarely.

Plausible: Evidence is real but thin, or it matches a well-established pattern. Not yet reproduced.

Test status

We haven't reproduced this yet. When we do, measured accuracy, latency, and cost will appear here next to the claimed figures.
