What happened

Summary

Jeff 是一组从 Qwen3.5 和 Gemma 4 微调出来的 0.8B 参数小模型,专门做零样本分类——也就是不给例子直接判断类别。亮点是作者说在家用普通显卡上就能训练,推理一次只要 30 毫秒左右,延迟很低,适合塞进实时决策流程。模型兼容 Jev 格式,GitHub 上放了代码和权重。不过正文没披露用了多大训练集、在什么基准上测过,所以实际效果...

    Jeff: 0.8B decision models trained at home, ~30 ms inference

    Jeff is a set of 0.8B parameter models fine-tuned from Qwen3.5 and Gemma 4 for zero-shot classification. Trained on consumer hardware at home, it runs inference in ~30 ms and is Jev-compatible. The post doesn't disclose dataset size or benchmarks, but the GitHub repo includes code and weights. For teams needing lightweight decision pipelines, the latency and size are practical.
