openjev (now SemIf): a Jev-style model on one RTX 3090
VerifiedNot yet tested by usOther model
The claim
Runs a Jev-style decision model locally on a single consumer GPU.
Our read
Real and runnable. It is not Jev, and its accuracy is its own.
Verified: The thing exists and the core claim checks out against a source you can open.
Test status
We haven't reproduced this yet. When we do, measured accuracy, latency, and cost will appear here next to the claimed figures.
