I didn't look specifically at open-source but I evaluated as many decision models as I could on openrouter against how good are they at detecting phishing, which isn't the best use of these models but I was interested to see how they compared. https://emdashcyber.com/phishnchips-decision-models/

I had my first use case recently, and did some very non-systematic benchmarking of models on OpenRouter.

The only one that came close to Jev itself was the one from respan (respan/span-02), which is also open source and cheaper too.
