For the specific topic of running chains, for high workloads we saw the potential improvement that Async calls have, so my recommendation is to take the time to understand what the code is doing and To run parallel chains with different configurations for each chain in the _demo_parallel function, you can use the RunnableParallel class to define each chain with its specific configuration. However, these approaches neglect to incorporate valuable feedback, such as environment rewards, to enhance the agent’s behaviors, resulting in performances that rely solely on the quality of the pre- LangChain is used as the basis for this prototype, LangChain is a widely used open-source library for building LLM-based applications. Most LLMs have a maximum supported context window (denominated in tokens). This post outlines how to build 3 reflection techniques using LangGraph, including implementations of Reflexion and Language Agent Tree Search. Beyond Agent系列之LangChain中ReAct的实现原理浅析.
