This pull request introduces a new feature to the OpenAIEmbeddings
class within the langchain_openai
package, allowing users to disable the safe_len_embedding
functionality when interacting with OpenAI API compatible servers that may not support this feature. The implementation adds a new boolean attribute disable_safe_len_embeddings
to the class, which defaults to False
. When set to True
, the embedding methods (embed_documents
and aembed_documents
) bypass the length-safe embedding function and directly call the OpenAI API (or compatible server) to generate embeddings for each text in the input list.
The code changes are straightforward and well-contained within the existing structure of the OpenAIEmbeddings
class. The addition of this feature enhances flexibility for users working with different OpenAI API compatible servers, providing them with an option to toggle the length safety mechanism based on the capabilities of their specific server.
From a code quality perspective, the changes are clear and follow the existing coding conventions of the project. The use of type annotations and docstrings would further improve readability and maintainability, especially for public methods and new attributes. Additionally, considering potential future enhancements or changes in API compatibility, it might be beneficial to include validation or logging around this new feature to assist users in troubleshooting and understanding the implications of disabling length safety.
Overall, this pull request represents a minor yet useful enhancement to the langchain_openai
package, offering users more control over their interactions with OpenAI API compatible servers.

The change in this pull request involves modifying the invoke
method of a class to avoid mutating the metadata
and tags
fields directly. Instead, it creates new dictionaries and lists by combining the existing ones with those from the instance (self
). This approach avoids side effects that can occur from directly modifying the input parameters, which is a good practice for maintaining code that is easier to understand and debug.
The use of dictionary unpacking (**
) and list concatenation (+
) are standard Python techniques for creating new composite objects without altering the originals. This change improves the code's safety by ensuring that the original config
object passed to the method remains unchanged outside the method's scope.
Overall, this is a small but meaningful improvement in code quality, focusing on immutability and side-effect-free programming. The commit message is clear and to the point, though it could benefit from a bit more context on why this change was necessary or what problem it solves. The code change itself is straightforward and uses idiomatic Python.
