LangServe Playground and Configurability

LangServe, launched last week, provides an easy way to deploy chains and agents in a production-ready manner. This week, additions include a playground and configurability. The playground allows users to change the values of certain parameters and try different inputs with real-time streaming responses. It also offers a simple UI for sharing with colleagues. Configurability enables experimentation with different components and configurations, which can be saved via URLs. LangServe is part of LangChain Expression Language and aims to facilitate common architectures for LLM applications by providing a GUI for easier collaboration.
