ENH: Add `llm_kwargs` for Xinference LLMs (#10354)
- This pr adds `llm_kwargs` to the initialization of Xinference LLMs
(integrated in #8171 ).
- With this enhancement, users can not only provide `generate_configs`
when calling the llms for generation but also during the initialization
process. This allows users to include custom configurations when
utilizing LangChain features like LLMChain.
- It also fixes some format issues for the docstrings.

Fix typing in WebResearchRetriver (#10734)
Hello @hwchase17 

**Issue**:
The class WebResearchRetriever accept only
RecursiveCharacterTextSplitter, but never uses a specification of this
class. I propose to change the type to TextSplitter. Then, the lint can
accept all subtypes.

Bug fixes for runnables (#10738)
- tools invoked in async methods would not work due to missing await
- RunnableSequence.stream() was creating an extra root run by mistake,
and it can simplified due to existence of default implementation for

OpenAI function calling docstring and notebook imports (#10663)
This PR is a documentation fix.

Description:
* fixes imports in the code samples in the docstrings of
`create_openai_fn_chain` and `create_structured_output_chain`
* fixes imports in
`docs/extras/modules/chains/how_to/openai_functions.ipynb`
* removes unused imports from the notebook

Issues:
* the docstrings use `from pydantic_v1 import BaseModel, Field` which
this PR changes to `from langchain.pydantic_v1 import BaseModel, Field`
* importing `pydantic` instead of `langchain.pydantic_v1` leads to
errors later in the notebook

CassandraCache and CassandraSemanticCache can handle any "Generation" (#10563)
Hello,
this PR improves coverage for caching by the two Cassandra-related
caches (i.e. exact-match and semantic alike) by switching to the more
general `dumps`/`loads` serdes utilities.

This enables cache usage within e.g. `ChatOpenAI` contexts (which need
to store lists of `ChatGeneration` instead of `Generation`s), which was
not possible as long as the cache classes were relying on the legacy
`_dump_generations_to_json` and `_load_generations_from_json`).

Additionally, a slightly different init signature is introduced for the
cache objects:
- named parameters required for init, to pave the way for easier changes
in the future connect-to-db flow (and tests adjusted accordingly)
- added a `skip_provisioning` optional passthrough parameter for use
cases where the user knows the underlying DB table, etc already exist.

Thank you for a review!

Cassandra Vector Store, add metadata filtering + improvements (#9280)
This PR addresses a few minor issues with the Cassandra vector store
implementation and extends the store to support Metadata search.

Thanks to the latest cassIO library (>=0.1.0), metadata filtering is
available in the store.

Further,
- the "relevance" score is prevented from being flipped in the [0,1]
interval, thus ensuring that 1 corresponds to the closest vector (this
is related to how the underlying cassIO class returns the cosine
difference);
- bumped the cassIO package version both in the notebooks and the
pyproject.toml;
- adjusted the textfile location for the vector-store example after the
reshuffling of the Langchain repo dir structure;
- added demonstration of metadata filtering in the Cassandra vector
store notebook;
- better docstring for the Cassandra vector store class;
- fixed test flakiness and removed offending out-of-place escape chars
from a test module docstring;

To my knowledge all relevant tests pass and mypy+black+ruff don't
complain. (mypy gives unrelated errors in other modules, which clearly
don't depend on the content of this PR).

Thank you!
Stefano

Fix SingleStoreDB (#10534)
After the refactoring #6570, the DistanceStrategy class was moved to
another module and this introduced a bug into the SingleStoreDB vector
store, as the `DistanceStrategy.EUCLEDIAN_DISTANCE` started to convert
into the 'DistanceStrategy.EUCLEDIAN_DISTANCE' string, instead of just
'EUCLEDIAN_DISTANCE' (same for 'DOT_PRODUCT').

In this change, I check the type of the parameter and use `.name`
attribute to get the correct object's name.

Using batches for update document with a new function in ChromaDB (#6561)
2a4b32dee2/langchain/vectorstores/chroma.py (L355-L375)

Currently, the defined update_document function only takes a single
document and its ID for updating. However, Chroma can update multiple
documents by taking a list of IDs and documents for batch updates. If we
update 'update_document' function both document_id and document can be
`Union[str, List[str]]` but we need to do type check. Because
embed_documents and update functions takes List for text and
document_ids variables. I believe that, writing a new function is the
best option.

I update the Chroma vectorstore with refreshed information from my
website every 20 minutes. Updating the update_document function to
perform simultaneous updates for each changed piece of information would
significantly reduce the update time in such use cases.

For my case I update a total of 8810 chunks. Updating these 8810
individual chunks using the current function takes a total of 8.5
minutes. However, if we process the inputs in batches and update them
collectively, all 8810 separate chunks can be updated in just 1 minute.
This significantly reduces the time it takes for users of actively used
chatbots to access up-to-date information.

I can add an integration test and an example for the documentation for
the new update_document_batch function.

Fix fine-tuned replicate models with faster cold boot (#10512)
With the latest support for faster cold boot in replicate
https://replicate.com/blog/fine-tune-cold-boots it looks like the
replicate LLM support in langchain is broken since some internal
replicate inputs are being returned.

Screenshot below illustrates the problem:

<img width="1917" alt="image"
src="https://github.com/langchain-ai/langchain/assets/749277/d28c27cc-40fb-4258-8710-844c00d3c2b0">

As you can see, the new replicate_weights param is being sent down with
x-order = 0 (which is causing langchain to use that param instead of
prompt which is x-order = 1)

FYI @baskaryan this requires a fix otherwise replicate is broken for
these models. I have pinged replicate whether they want to fix it on
their end by changing the x-order returned by them.

Update: per suggestion I updated the PR to just allow manually setting
the prompt_key which can be set to "prompt" in this case by callers... I
think this is going to be faster anyway than trying to dynamically query
the model every time if you know the prompt key for your model.

**Description**: 
Fixed a bug introduced in version 0.0.281 in

`self.table.delete_item(Key=self.key)` to resolve this issue.

Please see also [the official AWS

See also the PR, which introduced this bug:
https://github.com/langchain-ai/langchain/pull/9896#discussion_r1317899073

New LLM integration: Ctranslate2 (#10400)
## Description:

I've integrated CTranslate2 with LangChain. CTranlate2 is a recently
popular library for efficient inference with Transformer models that
compares favorably to alternatives such as HF Text Generation Inference
and vLLM in

enable serde retrieval qa with sources (#10132)
#3983 mentions serialization/deserialization issues with both
`RetrievalQA` & `RetrievalQAWithSourcesChain`.
`RetrievalQA` has already been fixed in #5818. 

Mimicing #5818, I added the logic for `RetrievalQAWithSourcesChain`.

add konko chat_model files (#10267)
_Thank you to the LangChain team for the great project and in advance
for your review. Let me know if I can provide any other additional
information or do things differently in the future to make your lives
easier 🙏 _

@hwchase17 please let me know if you're not the right person to review 😄

This PR enables LangChain to access the Konko API via the chat_models
API wrapper.

Konko API is a fully managed API designed to help application
developers:

1. Select the right LLM(s) for their application
2. Prototype with various open-source and proprietary LLMs
3. Move to production in-line with their security, privacy, throughput,
latency SLAs without infrastructure set-up or administration using Konko
AI's SOC 2 compliant infrastructure

_Note on integration tests:_ 
We added 14 integration tests. They will all fail unless you export the
right API keys. 13 will pass with a KONKO_API_KEY provided and the other
one will pass with a OPENAI_API_KEY provided. When both are provided,
all 14 integration tests pass. If you would like to test this yourself,
please let me know and I can provide some temporary keys.

### Installation and Setup

1. **First you'll need an API key**
2. **Install Konko AI's Python SDK**
    1. Enable a Python3.8+ environment
    
    `pip install konko`
    
3.  **Set API Keys**
    
          **Option 1:** Set Environment Variables
    
    You can set environment variables for
    
    1. KONKO_API_KEY (Required)
    2. OPENAI_API_KEY (Optional)
    
    In your current shell session, use the export command:
    
    `export KONKO_API_KEY={your_KONKO_API_KEY_here}`
    `export OPENAI_API_KEY={your_OPENAI_API_KEY_here} #Optional`
    
Alternatively, you can add the above lines directly to your shell
startup script (such as .bashrc or .bash_profile for Bash shell and
.zshrc for Zsh shell) to have them set automatically every time a new
shell session starts.
    
    **Option 2:** Set API Keys Programmatically
    
If you prefer to set your API keys directly within your Python script or
Jupyter notebook, you can use the following commands:
    
    ```python
    konko.set_api_key('your_KONKO_API_KEY_here')
    konko.set_openai_api_key('your_OPENAI_API_KEY_here') # Optional
    
    ```
    

### Calling a model

Find a model on the [[Konko Introduction
page](https://docs.konko.ai/docs#available-models)](https://docs.konko.ai/docs#available-models)

For example, for this [[LLama 2
model](https://docs.konko.ai/docs/meta-llama-2-13b-chat)](https://docs.konko.ai/docs/meta-llama-2-13b-chat).
The model id would be: `"meta-llama/Llama-2-13b-chat-hf"`

Another way to find the list of models running on the Konko instance is
through this
[[endpoint](https://docs.konko.ai/reference/listmodels)](https://docs.konko.ai/reference/listmodels).

From here, we can initialize our model:

```python
chat_instance = ChatKonko(max_tokens=10, model = 'meta-llama/Llama-2-13b-chat-hf')

```

And run it:

```python
msg = HumanMessage(content="Hi")
chat_response = chat_instance([msg])

```

Supabase vector self querying retriever (#10304)
## Description
Adds Supabase Vector as a self-querying retriever.

- Designed to be backwards compatible with existing `filter` logic on
`SupabaseVectorStore`.
- Adds new filter `postgrest_filter` to `SupabaseVectorStore`
`similarity_search()` methods
- Supports entire PostgREST [filter query
language](https://postgrest.org/en/stable/references/api/tables_views.html#read)
(used by self-querying retriever, but also works as an escape hatch for
more query control)
- `SupabaseVectorTranslator` converts Langchain filter into the above
PostgREST query
- Adds Jupyter Notebook for the self-querying retriever
- Adds tests
