Sergey Kozlov	df03267edf	Fix tool arguments formatting in StructuredChatAgent (#10480 ) In the `FORMAT_INSTRUCTIONS` template, 4 curly braces (escaping) are used to get single curly brace after formatting: ``` "{{{ ... }}}}" -> format_instructions.format() -> "{{ ... }}" -> template.format() -> "{ ... }". ``` Tool's `args_schema` string contains single braces `{ ... }`, and is also transformed to `{{{{ ... }}}}` form. But this is not really correct since there is only one `format()` call: ``` "{{{{ ... }}}}" -> template.format() -> "{{ ... }}". ``` As a result we get double curly braces in the prompt: ```` Respond to the human as helpfully and accurately as possible. You have access to the following tools: foo: Test tool FOO, args: {{'tool_input': {{'type': 'string'}}}} # <--- !!! ... Provide only ONE action per $JSON_BLOB, as shown: ``` { "action": $TOOL_NAME, "action_input": $INPUT } ``` ```` This PR fixes curly braces escaping in the `args_schema` to have single braces in the final prompt: ```` Respond to the human as helpfully and accurately as possible. You have access to the following tools: foo: Test tool FOO, args: {'tool_input': {'type': 'string'}} # <--- !!! ... Provide only ONE action per $JSON_BLOB, as shown: ``` { "action": $TOOL_NAME, "action_input": $INPUT } ``` ```` --------- Co-authored-by: Sergey Kozlov <sergey.kozlov@ludditelabs.io>	10 months ago
Wouter Durnez	ef7802b325	Add llama2-13b-chat-v1 support to `chat_models.BedrockChat` (#13403 ) Hi 👋 We are working with Llama2 on Bedrock, and would like to add it to Langchain. We saw a [pull request](https://github.com/langchain-ai/langchain/pull/13322) to add it to the `llm.Bedrock` class, but since it concerns a chat model, we would like to add it to `BedrockChat` as well. - Description: Add support for Llama2 to `BedrockChat` in `chat_models` - Issue: the issue # it fixes (if applicable) [#13316](https://github.com/langchain-ai/langchain/issues/13316) - Dependencies: any dependencies required for this change `None` - Tag maintainer: / - Twitter handle: `@SimonBockaert @WouterDurnez` --------- Co-authored-by: wouter.durnez <wouter.durnez@showpad.com> Co-authored-by: Simon Bockaert <simon.bockaert@showpad.com>	10 months ago

Massimiliano Pronesti	6bf9b2cb51	BUG: Limit Azure OpenAI embeddings chunk size (#13425 ) Hi! This short PR aims at: * Fixing `OpenAIEmbeddings`' check on `chunk_size` when used with Azure OpenAI (thus with openai < 1.0). Azure OpenAI embeddings support at most 16 chunks per batch, I believe we are supposed to take the min between the passed value/default value and 16, not the max - which, I suppose, was introduced by accident while refactoring the previous version of this check from this other PR of mine: #10707 * Porting this fix to the newest class (`AzureOpenAIEmbeddings`) for openai >= 1.0 This fixes #13539 (closed but the issue persists). @baskaryan @hwchase17	10 months ago

Martin Krasser	79ed66f870	EXPERIMENTAL Generic LLM wrapper to support chat model interface with configurable chat prompt format (#8295 ) ## Update 2023-09-08 This PR now supports further models in addition to Lllama-2 chat models. See [this comment](#issuecomment-1668988543) for further details. The title of this PR has been updated accordingly. ## Original PR description This PR adds a generic `Llama2Chat` model, a wrapper for LLMs able to serve Llama-2 chat models (like `LlamaCPP`, `HuggingFaceTextGenInference`, ...). It implements `BaseChatModel`, converts a list of chat messages into the [required Llama-2 chat prompt format](https://huggingface.co/blog/llama2#how-to-prompt-llama-2) and forwards the formatted prompt as `str` to the wrapped `LLM`. Usage example: ```python # uses a locally hosted Llama2 chat model llm = HuggingFaceTextGenInference( inference_server_url="http://127.0.0.1:8080/", max_new_tokens=512, top_k=50, temperature=0.1, repetition_penalty=1.03, ) # Wrap llm to support Llama2 chat prompt format. # Resulting model is a chat model model = Llama2Chat(llm=llm) messages = [ SystemMessage(content="You are a helpful assistant."), MessagesPlaceholder(variable_name="chat_history"), HumanMessagePromptTemplate.from_template("{text}"), ] prompt = ChatPromptTemplate.from_messages(messages) memory = ConversationBufferMemory(memory_key="chat_history", return_messages=True) chain = LLMChain(llm=model, prompt=prompt, memory=memory) # use chat model in a conversation # ... ``` Also part of this PR are tests and a demo notebook. - Tag maintainer: @hwchase17 - Twitter handle: `@mrt1nz` --------- Co-authored-by: Erick Friis <erick@langchain.dev>	10 months ago
