Streamlit and LangChain are partnering for an LLM Hackathon. The event aims to bring together developers to create innovative applications using the Streamlit platform and the LangChain framework. This collaboration seeks to facilitate the creation of large language model (LLM) apps, with various resources and examples provided to guide participants. LangChain has launched a Prompt Hub to help developers build faster and smarter, and they encourage contributions from the community. The hackathon aims to showcase practical, innovative, and adventurous applications, including those using open-source models, unique data sources, and advanced retrieval tactics. Participants are invited to share their projects on Twitter and provide feedback throughout the event.
