Vespa support in langchain

Vespa has introduced support for Langchain, simplifying the use of large language models (LLMs) in applications by incorporating a Vespa retriever into Langchain's framework. This integration is aimed at enhancing the functionality for developers working with LLMs, making it easier to experiment and deploy these models. The collaboration between Vespa and Langchain is acknowledged, with appreciation extended to Langchain creator Harrison Chase for his insights regarding Vespa's integration. Further details and documentation on this development can be found on the Langchain website.
