jev-claim-vs-measured
A post with ~400k views says TypeSafe's **Jev** is the fastest AI model ever built for trading, makes calibrated buy/sell decisions in under 100 ms, and shows how to build an HFT system on it. The article behind it contains no backtest, no P&L and no hit rate. So I ran the tests: on the raw tape at one decision per second, and at 15–60 minute horizons. It cost **$0.97** of API credit. Everything needed to check me is in this repository.

What Jev does here
Jev returns a structured decision for the local program; consult the source for the exact decision policy.
Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.
Based on repository metadata and README with rule-based classification; pending human review, with no independent runtime or performance verification.
