ccurme	975b6129f6	core[patch]: support conversion of runnables to tools (#23992 ) Open to other thoughts on UX. string input: ```python as_tool = retriever.as_tool() as_tool.invoke("cat") # [Document(...), ...] ``` typed dict input: ```python class Args(TypedDict): key: int def f(x: Args) -> str: return str(x["key"] * 2) as_tool = RunnableLambda(f).as_tool( name="my tool", description="description", # name, description are inferred if not supplied ) as_tool.invoke({"key": 3}) # "6" ``` for untyped dict input, allow specification of parameters + types ```python def g(x: Dict[str, Any]) -> str: return str(x["key"] * 2) as_tool = RunnableLambda(g).as_tool(arg_types={"key": int}) result = as_tool.invoke({"key": 3}) # "6" ``` Passing the `arg_types` is slightly awkward but necessary to ensure tool calls populate parameters correctly: ```python from typing import Any, Dict from langchain_core.runnables import RunnableLambda from langchain_openai import ChatOpenAI def f(x: Dict[str, Any]) -> str: return str(x["key"] * 2) runnable = RunnableLambda(f) as_tool = runnable.as_tool(arg_types={"key": int}) llm = ChatOpenAI().bind_tools([as_tool]) result = llm.invoke("Use the tool on 3.") tool_call = result.tool_calls[0] args = tool_call["args"] assert args == {"key": 3} as_tool.run(args) ``` Contrived (?) example with langgraph agent as a tool: ```python from typing import List, Literal from typing_extensions import TypedDict from langchain_openai import ChatOpenAI from langgraph.prebuilt import create_react_agent llm = ChatOpenAI(temperature=0) def magic_function(input: int) -> int: """Applies a magic function to an input.""" return input + 2 agent_1 = create_react_agent(llm, [magic_function]) class Message(TypedDict): role: Literal["human"] content: str agent_tool = agent_1.as_tool( arg_types={"messages": List[Message]}, name="Jeeves", description="Ask Jeeves.", ) agent_2 = create_react_agent(llm, [agent_tool]) ``` --------- Co-authored-by: Erick Friis <erick@langchain.dev>	3 months ago

ccurme	74c7198906	core, anthropic[patch]: support streaming tool calls when function has no arguments (#23915 ) resolves https://github.com/langchain-ai/langchain/issues/23911 When an AIMessageChunk is instantiated, we attempt to parse tool calls off of the tool_call_chunks. Here we add a special-case to this parsing, where `""` will be parsed as `{}`. This is a reaction to how Anthropic streams tool calls in the case where a function has no arguments: ``` {'id': 'toolu_01J8CgKcuUVrMqfTQWPYh64r', 'input': {}, 'name': 'magic_function', 'type': 'tool_use', 'index': 1} {'partial_json': '', 'type': 'tool_use', 'index': 1} ``` The `partial_json` does not accumulate to a valid json string-- most other providers tend to emit `"{}"` in this case.	3 months ago
Christophe Bornet	42d049f618	core[minor]: Add Graph Store component (#23092 ) This PR introduces a GraphStore component. GraphStore extends VectorStore with the concept of links between documents based on document metadata. This allows linking documents based on a variety of techniques, including common keywords, explicit links in the content, and other patterns. This works with existing Documents, so it’s easy to extend existing VectorStores to be used as GraphStores. The interface can be implemented for any Vector Store technology that supports metadata, not only graph DBs. When retrieving documents for a given query, the first level of search is done using classical similarity search. Next, links may be followed using various traversal strategies to get additional documents. This allows documents to be retrieved that aren’t directly similar to the query but contain relevant information. 2 retrieving methods are added to the VectorStore ones : * traversal_search which gets all linked documents up to a certain depth * mmr_traversal_search which selects linked documents using an MMR algorithm to have more diverse results. If a depth of retrieval of 0 is used, GraphStore is effectively a VectorStore. It enables an easy transition from a simple VectorStore to GraphStore by adding links between documents as a second step. An implementation for Apache Cassandra is also proposed. See https://github.com/datastax/ragstack-ai/blob/main/libs/knowledge-store/notebooks/astra_support.ipynb for a notebook explaining how to use GraphStore and that shows that it can answer correctly to questions that a simple VectorStore cannot.

Eugene Yurtsev	6f08e11d7c	core[minor]: add upsert, streaming_upsert, aupsert, astreaming_upsert methods to the VectorStore abstraction (#23774 ) This PR rolls out part of the new proposed interface for vectorstores (https://github.com/langchain-ai/langchain/pull/23544) to existing store implementations. The PR makes the following changes: 1. Adds standard upsert, streaming_upsert, aupsert, astreaming_upsert methods to the vectorstore. 2. Updates `add_texts` and `aadd_texts` to be non required with a default implementation that delegates to `upsert` and `aupsert` if those have been implemented. The original `add_texts` and `aadd_texts` methods are problematic as they spread object specific information across document and *kwargs. (e.g., ids are not a part of the document) 3. Adds a default implementation to `add_documents` and `aadd_documents` that delegates to `upsert` and `aupsert` respectively. 4. Adds standard unit tests to verify that a given vectorstore implements a correct read/write API. A downside of this implementation is that it creates `upsert` with a very similar signature to `add_documents`. The reason for introducing `upsert` is to: Remove any ambiguities about what information is allowed in `kwargs`. Specifically kwargs should only be used for information common to all indexed data. (e.g., indexing timeout). *Allow inheriting from an anticipated generalized interface for indexing that will allow indexing `BaseMedia` (i.e., allow making a vectorstore for images/audio etc.) `add_documents` can be deprecated in the future in favor of `upsert` to make sure that users have a single correct way of indexing content. --------- Co-authored-by: ccurme <chester.curme@gmail.com>	3 months ago

Mohammad Mohtashim	2274d2b966	core[patch]: Accounting for Optional Input Variables in BasePromptTemplate (#22851 ) Description: After reviewing the prompts API, it is clear that the only way a user can explicitly mark an input variable as optional is through the `MessagePlaceholder.optional` attribute. Otherwise, the user must explicitly pass in the `input_variables` expected to be used in the `BasePromptTemplate`, which will be validated upon execution. Therefore, to semantically handle a `MessagePlaceholder` `variable_name` as optional, we will treat the `variable_name` of `MessagePlaceholder` as a `partial_variable` if it has been marked as optional. This approach aligns with how the `variable_name` of `MessagePlaceholder` is already handled [here](https://github.com/keenborder786/langchain/blob/optional_input_variables/libs/core/langchain_core/prompts/chat.py#L991). Additionally, an attribute `optional_variable` has been added to `BasePromptTemplate`, and the `variable_name` of `MessagePlaceholder` is also made part of `optional_variable` when marked as optional. Moreover, the `get_input_schema` method has been updated for `BasePromptTemplate` to differentiate between optional and non-optional variables.

This fixes that by keeping track of the current depth and using a stack.	3 months ago

Eugene Yurtsev	b5aef4cf97	core[patch]: Fix llm string representation for serializable models (#23416 ) Fix LLM string representation for serializable objects. Fix for issue: https://github.com/langchain-ai/langchain/issues/23257 The llm string of serializable chat models is the serialized representation of the object. LangChain serialization dumps some basic information about non serializable objects including their repr() which includes an object id. This means that if a chat model has any non serializable fields (e.g., a cache), then any new instantiation of the those fields will change the llm representation of the chat model and cause chat misses. i.e., re-instantiating a postgres cache would result in cache misses!	3 months ago

Eugene Yurtsev	4f1821db3e	core[minor]: Add get_by_ids to vectorstore interface (#23594 ) This PR adds a part of the indexing API proposed in this RFC https://github.com/langchain-ai/langchain/pull/23544/files. It allows rolling out `get_by_ids` which should be uncontroversial to existing vectorstores without introducing new abstractions. The semantics for this method depend on the ability of identifying returned documents using the new optional ID field on documents: https://github.com/langchain-ai/langchain/pull/23411 Alternatives are: 1. Relax the sequence requirement ```python def get_by_ids(self, ids: Iterable[str], /) -> Iterable[Document]: ``` Rejected: - implementations are more likley to start batching with bad defaults - users would need to call list() or we'd need to introduce another convenience method 2. Support more kwargs ```python def get_by_ids(self, ids: Sequence[str], /, **kwargs) -> List[Document]: ... ``` Rejected: - No need for `batch` parameter since IDs is a sequence - Output cannot be customized since `Document` is fixed. (e.g., parameters could be useful to grab extra metadata like the vector that was indexed with the Document or to project a part of the document)	3 months ago

Eugene Yurtsev	96b72edac8	core[minor]: Add optional ID field to Document schema (#23411 ) This PR adds an optional ID field to the document schema. # 1. Optional or Required - An optional field will will requrie additional checking for the type in user code (annoying). - However, vectorstores currently don't respect this field. So if we make it required and start returning random UUIDs that might be even more confusing to users. Proposal: Start with Optional and convert to Required (with default set to uuid4()) in 1-2 major releases. # 2. Override __str__ or generic solution in prompts Overriding __str__ as a simple way to avoid changing user code that relies on default str(document) in prompts. I considered rolling out a more general solution in prompts (https://github.com/langchain-ai/langchain/pull/8685), but to do that we need to: 1. Make things serializable 2. The more general solution would likely need to be backwards compatible as well 3. It's unclear that one wants to format a List[int] in the same way as List[Document]. The former should be `,` seperated (likely), the latter should be `---` separated (likely). Proposal Start with __str__ override and focus on the vectorstore APIs, we generalize prompts later	3 months ago

Eugene Yurtsev	9120cf5df2	core[patch]: Deduplicate of callback handlers in merge_configs (#22478 ) This PR adds deduplication of callback handlers in merge_configs. Fix for this issue: https://github.com/langchain-ai/langchain/issues/22227 The issue appears when the code is: 1) running python >=3.11 2) invokes a runnable from within a runnable 3) binds the callbacks to the child runnable from the parent runnable using with_config In this case, the same callbacks end up appearing twice: (1) the first time from with_config, (2) the second time with langchain automatically propagating them on behalf of the user. Prior to this PR this will emit duplicate events: ```python @tool async def get_items(question: str, callbacks: Callbacks): # <--- Accept callbacks """Ask question""" template = ChatPromptTemplate.from_messages( [ ( "human", "'{question}" ) ] ) chain = template \| chat_model.with_config( { "callbacks": callbacks, # <-- Propagate callbacks } ) return await chain.ainvoke({"question": question}) ``` Prior to this PR this will work work correctly (no duplicate events): ```python @tool async def get_items(question: str, callbacks: Callbacks): # <--- Accept callbacks """Ask question""" template = ChatPromptTemplate.from_messages( [ ( "human", "'{question}" ) ] ) chain = template \| chat_model return await chain.ainvoke({"question": question}, {"callbacks": callbacks}) ``` This will also work (as long as the user is using python >= 3.11) -- as langchain will automatically propagate callbacks ```python @tool async def get_items(question: str,): """Ask question""" template = ChatPromptTemplate.from_messages( [ ( "human", "'{question}" ) ] ) chain = template \| chat_model return await chain.ainvoke({"question": question}) ```	4 months ago

Jacob Lee	c01467b1f4	core[patch]: RFC: Allow concatenation of messages with multi part content (#22002 ) Anthropic's streaming treats tool calls as different content parts (streamed back with a different index) from normal content in the `content`. This means that we need to update our chunk-merging logic to handle chunks with multi-part content. The alternative is coerceing Anthropic's responses into a string, but we generally like to preserve model provider responses faithfully when we can. This will also likely be useful for multimodal outputs in the future. This current PR does unfortunately make `index` a magic field within content parts, but Anthropic and OpenAI both use it at the moment to determine order anyway. To avoid cases where we have content arrays with holes and to simplify the logic, I've also restricted merging to chunks in order. TODO: tests CC @baskaryan @ccurme @efriis	4 months ago

Eugene Yurtsev	5c2cfabec6	core[minor]: Add v2 implementation of astream events (#21638 ) This PR introduces a v2 implementation of astream events that removes intermediate abstractions and fixes some issues with v1 implementation. The v2 implementation significantly reduces relevant code that's associated with the astream events implementation together with overhead. After this PR, the astream events implementation: - Uses an async callback handler - No longer relies on BaseTracer - No longer relies on json patch As a result of this re-write, a number of issues were discovered with the existing implementation. ## Changes in V2 vs. V1 ### on_chat_model_end `output` The outputs associated with `on_chat_model_end` changed depending on whether it was within a chain or not. As a root level runnable the output was: ```python "data": {"output": AIMessageChunk(content="hello world!", id='some id')} ``` As part of a chain the output was: ``` "data": { "output": { "generations": [ [ { "generation_info": None, "message": AIMessageChunk( content="hello world!", id=AnyStr() ), "text": "hello world!", "type": "ChatGenerationChunk", } ] ], "llm_output": None, } }, ``` After this PR, we will always use the simpler representation: ```python "data": {"output": AIMessageChunk(content="hello world!", id='some id')} ``` NOTE Non chat models (i.e., regular LLMs) are still associated with the more verbose format. ### Remove some `_stream` events `on_retriever_stream` and `on_tool_stream` events were removed -- these were not real events, but created as an artifact of implementing on top of astream_log. The same information is already available in the `x_on_end` events. ### Propagating Names Names of runnables have been updated to be more consistent ```python model = GenericFakeChatModel(messages=infinite_cycle).configurable_fields( messages=ConfigurableField( id="messages", name="Messages", description="Messages return by the LLM", ) ) ``` Before: ```python "name": "RunnableConfigurableFields", ``` After: ```python "name": "GenericFakeChatModel", ``` ### on_retriever_end on_retriever_end will always return `output` which is a list of documents (rather than a dict containing a key called "documents") ### Retry events Removed the `on_retry` callback handler. It was incorrectly showing that the failed function being retried has invoked `on_chain_end` https://github.com/langchain-ai/langchain/pull/21638/files#diff-e512e3f84daf23029ebcceb11460f1c82056314653673e450a5831147d8cb84dL1394	4 months ago
