Overview

Method for initializing an IPEX-LLM-accelerated language model as a LangChain LLM for use in chains and agents.

Description

LLM Initialization for LangChain wraps an IPEX-LLM-optimized model in the LangChain LLM interface, enabling it to be used in LangChain chains, agents, and LCEL pipelines. The IpexLLM.from_model_id class loads a HuggingFace model with IPEX-LLM optimizations on XPU, and exposes it through the standard LangChain LLM interface (supporting invoke, predict, and streaming).

Usage

Use when integrating IPEX-LLM models into LangChain workflows such as RAG chains, chat agents, or custom LCEL pipelines.

Theoretical Basis

# Abstract LangChain LLM interface (NOT real implementation)
# LangChain LLM contract:
# llm.invoke(prompt: str) -> str
# llm.predict(prompt: str) -> str
# llm.stream(prompt: str) -> Iterator[str]
# IpexLLM wraps the HuggingFace model to implement this interface
