When importing voyageai in Python 3.14, this error occurs:

It is impossible to keep using voyageai as our company updates to 3.14, it is such a simple fix, can't it be done asap?

[fzliu]

Python 3.14 support was added in #46

[sghng]

Can confirm that this package works ok for me now.

EDIT: no it still doesn't work. the HTTP endpoint was used instead of Python SDK

[Leomconti]

There is no new version tagged after this #46 merge though? What am I missing?
Also no support for 3.14 shown in https://pypi.org/project/voyageai/

[ilanbenb]

Please release v3.8 for this :)

[violuke]

Following merge of #46 can a new release be made please. @kenhong @fzliu 🙏

[panzi]

Is there any rough ETA on when there will be a release with this fixed? I think this is the last of our dependencies keeping us from using Python 3.14+.

Looked at our dependencies more closely: voyageai also depends on langchain-text-splitters which depends on langchain-core which still uses pydantic.v1. But it only uses it for issublcass() and never instantiates it. So that might be fine and thus voyageai is probably really the last of our dependencies that holds us back.

It's surprising to see that this SDK depends on langchain... I think it's a terrible idea for the official SDK of an embedding provider to depend on that kind of downstream utilities...
