We are introducing the py integration to Javelin AI Gateway
www.getjavelin.io. Javelin is an enterprise-scale fast llm router &
gateway. Could you please review and let us know if there is anything
missing.
Javelin AI Gateway wraps Embedding, Chat and Completion LLMs. Uses
javelin_sdk under the covers (pip install javelin_sdk).

### Description
- Add support for streaming with `Bedrock` LLM and `BedrockChat` Chat
Model.
- Bedrock as of now supports streaming for the `anthropic.claude-*` and
`amazon.titan-*` models only, hence support for those have been built.
- Also increased the default `max_token_to_sample` for Bedrock
`anthropic` model provider to `256` from `50` to keep in line with the
`Anthropic` defaults.
- Added examples for streaming responses to the bedrock example
notebooks.
**_NOTE:_**: This PR fixes the issues mentioned in #9897 and makes that
PR redundant.
- **Description:** QianfanEndpoint bugs for SystemMessages. When the
`SystemMessage` is input as the messages to
`chat_models.QianfanEndpoint`. A `TypeError` will be raised.
- **Issue:** #10643

This PR addresses the limitation of Azure OpenAI embeddings, which can
handle at maximum 16 texts in a batch. This can be solved setting
`chunk_size=16`. However, I'd love to have this automated, not to force
the user to figure where the issue comes from and how to solve it.
Closes#4575.

**Description:**
changed return parameter of YouTubeSearchTool
1. changed the returning links of youtube videos by adding prefix
"https://www.youtube.com", now this will return the exact links to the
videos
2. updated the returning type from 'string' to 'list', which will be
more suited for further processings
**Issue:**
Fixes#10742

**Description:** This PR adds HTTP PUT support for the langchain openapi
agent toolkit by leveraging existing structure and HTTP put request
wrapper. The PUT method is almost identical to HTTP POST but should be
idempotent and therefore tighter than POST which is not idempotent. Some
APIs may consider to use PUT instead of POST which is unfortunately not
supported with the current toolkit yet.
### Description
Implements synthetic data generation with the fields and preferences
given by the user. Adds showcase notebook.
Corresponding prompt was proposed for langchain-hub.
### Example
```
output = chain({"fields": {"colors": ["blue", "yellow"]}, "preferences": {"style": "Make it in a style of a weather forecast."}})
print(output)
# {'fields': {'colors': ['blue', 'yellow']},
'preferences': {'style': 'Make it in a style of a weather forecast.'},
'text': "Good morning! Today's weather forecast brings a beautiful combination of colors to the sky, with hues of blue and yellow gently blending together like a mesmerizing painting."}
```

**Description:** upgrade the `dataclasses_json` dependency to its latest
version ([no real breaking
change](https://github.com/lidatong/dataclasses-json/releases/tag/v0.6.0)
if used correctly), while allowing previous version to not break other
users' setup
**Issue:** I need to use the latest version of that dependency in my
project, but `langchain` prevents it.
Note: it looks like running `poetry lock --no-update` did some changes
to the lockfiles as it was the first time it was with the
`macosx_11_0_arm64` architecture 🤷

Description:
If metadata field returned in results, previous behavior unchanged. If
metadata field does not exist in results, expand metadata to any fields
returned outside of content field.
There's precedence for this as well, see the retriever:
https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/retrievers/azure_cognitive_search.py#L96C46-L96C46
Issue:
#9765 - Ameliorates hard-coding in case you already indexed to cognitive
search without a metadata field but rather placed metadata in separate
fields.

## Description
This PR updates the `NeptuneGraph` class to start using the boto API for
connecting to the Neptune service. With boto integration, the graph
class now supports authenticating requests using Sigv4; this is
encapsulated with the boto API, and users only have to ensure they have
the correct AWS credentials setup in their workspace to work with the
graph class.
This PR also introduces a conditional prompt that uses a simpler prompt
when using the `Anthropic` model provider. A simpler prompt have seemed
to work better for generating cypher queries in our testing.
**Note**: This version will require boto3 version 1.28.38 or greater to
work.
**Description:**
This commit enriches the `WeaviateHybridSearchRetriever` class by
introducing a new parameter, `hybrid_search_kwargs`, within the
`_get_relevant_documents` method. This parameter accommodates arbitrary
keyword arguments (`**kwargs`) which can be channeled to the inherited
public method, `get_relevant_documents`, originating from the
`BaseRetriever` class.
This modification facilitates more intricate querying capabilities,
allowing users to convey supplementary arguments to the `.with_hybrid()`
method. This expansion not only makes it possible to perform a more
nuanced search targeting specific properties but also grants the ability
to boost the weight of searched properties, to carry out a search with a
custom vector, and to apply the Fusion ranking method. The documentation
has been updated accordingly to delineate these new possibilities in
detail.
In light of the layered approach in which this search operates,
initiating with `query.get()` and then transitioning to
`.with_hybrid()`, several advantageous opportunities are unlocked for
the hybrid component that were previously unattainable.
Here’s a representative example showcasing a query structure that was
formerly unfeasible:
[Specific Properties
Only](https://weaviate.io/developers/weaviate/search/hybrid#selected-properties-only)
"The example below illustrates a BM25 search targeting the keyword
'food' exclusively within the 'question' property, integrated with
vector search results corresponding to 'food'."
```python
response = (
client.query
.get("JeopardyQuestion", ["question", "answer"])
.with_hybrid(
query="food",
properties=["question"], # Will now be possible moving forward
alpha=0.25
)
.with_limit(3)
.do()
)
```
This functionality is now accessible through my alterations, by
conveying `hybrid_search_kwargs={"properties": ["question", "answer"]}`
as an argument to
`WeaviateHybridSearchRetriever.get_relevant_documents()`. For example:
```python
import os
from weaviate import Client
from langchain.retrievers import WeaviateHybridSearchRetriever
client = Client(
url=os.getenv("WEAVIATE_CLIENT_URL"),
additional_headers={
"X-OpenAI-Api-Key": os.getenv("OPENAI_API_KEY"),
"Authorization": f"Bearer {os.getenv('WEAVIATE_API_KEY')}",
},
)
index_name = "Document"
text_key = "content"
attributes = ["title", "summary", "header", "url"]
retriever = ExtendedWeaviateHybridSearchRetriever(
client=client,
index_name=index_name,
text_key=text_key,
attributes=attributes,
)
# Warning: to utilize properties in this way, each use property must also be in the list `attributes + [text_key]`.
hybrid_search_kwargs = {"properties": ["summary^2", "content"]}
query_text = "Some Query Text"
relevant_docs = retriever.get_relevant_documents(
query=query_text,
hybrid_search_kwargs=hybrid_search_kwargs
)
```
In my experience working with the `weaviate-client` library, I have
found that these supplementary options stand as vital tools for
refining/finetuning searches, notably within multifaceted datasets. As a
final note, this implementation supports both backwards and forward
(within reason) compatiblity. It accommodates any future additional
parameters Weaviate may add to `.with_hybrid()`, without necessitating
further alterations.

@hwchase17 - I have tagged you based on your frequent contributions to

Thank you for considering my contribution, I look forward to your
feedback, and to future collaboration.
I was trying to use web loaders on some spanish documentation (e.g.
[this site](https://www.fromdoppler.com/es/mailing-tendencias/), but the
auto-encoding introduced in
https://github.com/langchain-ai/langchain/pull/3602 was detected as
"MacRoman" instead of the (correct) "UTF-8".
To address this, I've added the ability to disable the auto-encoding, as
well as the ability to explicitly tell the loader what encoding to use.
- **Description:** Makes auto-setting the encoding optional in
`WebBaseLoader`, and introduces an `encoding` option to explicitly set
it.
