Hi, @hwchase17! I'm Dosu, and I'm helping the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.

From what I understand, the issue is a request to add AI21 Embeddings support, but there are no further details provided. In the comments, there is some discussion about whether AI21 offers embeddings through an API, and one user suggests that the issue may already be resolved and can be closed, providing a link to the relevant code. Another user asks if they can work on the issue, and another user states that the issue has been solved on another thread. Finally, a user asks if the issue is solved or if they can assign it to themselves, receiving positive reactions from other users.

Before we close this issue, we wanted to check with you if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.

Thank you for your understanding and contribution to the LangChain project!
