FWIW I think the actual Jev Model by TypeSafe has some solid potential, but its potential is gated by its properity architecture.
Until they release what they did to reach their performance and cost, the open-source variants will keep falling short
Also another issue is a lot of these "open-sourced' jev models are just running some LoRa/distilled/fine-tuned variant of QWEN which from a cost perspective makes no sense when at that point youre better off hosting QWEN
