Jeva-4B

Like 43

Hi Qi and Xinchao,

Thanks for releasing Jeva. The paper and the cache/reuse design are really interesting, and we'd like to evaluate Jeva-4B for request routing and classification in a production setting.

The GitHub code is clearly Apache-2.0, and the README notes that model weights retain their respective licenses. However, this model repo doesn't have a license tag or LICENSE file. The Qwen3.5-4B backbone is Apache-2.0, but it's unclear what terms apply to the parts you trained (head.pt and backbone_adapter/).

Could you clarify:

1. What license applies to the Jeva-4B weights?
2. Is commercial use (including self-hosting behind a paid product) permitted?
3. Are there any restrictions from the training data we should be aware of?

If it's Apache-2.0 like the code, adding license: apache-2.0 to the model card metadata would make this clear for everyone downloading it.

Thanks again for the work!
