Hi, we're currently testing py3.13 (rc3) viability in our project and is most likely blocked by this PR through the python sdk from openai.

openai==1.51.0
├── jiter [required: >=0.4.0,<1, installed: 0.5.0]

Do you have any estimations on when this PR will be merged (and a new version published)?
Thanks!
