Five open Jev replicas, in Chinese
小墨同学 on Laya 421M, Decider-2B, NanoJev 0.6B, Reflex and System-One 4B, and which run best on Apple silicon.
Open x.com ↗Jev 发布没几天，开源社区已经开始疯狂复刻了🔥
最值得推荐的五个模型：
1、Laya 421M：原生决策模型，支持 Mac
2、Decider-2B：最像 Jev，基于 Qwen3.5
3、NanoJev 0.6B：专门的 Decision Head
4、Reflex：Qwen3.5 + Direct Logits
5、System-One 4B：专门做概率校准
How builders describe it
A Chinese-language roundup of open System One efforts including Laya 421M, Decider-2B, NanoJev 0.6B, Reflex, and System-One 4B, with parameter counts.
The decision Jev makes
Benchmark questions with known answers, to check accuracy and confidence.
Where it fits
Head-to-head tests, calibration studies and independent research into how well Jev decides, how fast, and at what cost. All 682 benchmarks & research projects →
