I haven't evaluated this one, but for what I have, it seem the pplx-decider-v1.2 (and its -flash variant) are pretty good. Anyone evaluated all these open-source decision models on their own tasks? (I evaluated on MonitoringBench).
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.
You might also be interested in this index for decision models: https://huggingface.co/spaces/multimodalart/jev-decision-ind...
Thanks for the index. I will try to navigate it. For now I cannot even find this respan/span-02 in it :/
