The TED AI Hackathon, beginning on October 14, is partnering with LangChain to inspire participants to build applications using large language models (LLMs) for potentially the first time, with a special prize for the best LLM application. To support developers, LangChain offers resources including installation instructions, a Quickstart guide, use-case-specific walkthroughs, YouTube tutorials, and a gallery of notable applications. Additionally, the newly launched LangChain Hub serves as a platform for sharing and discovering prompts, encouraging community collaboration to enhance prompting knowledge. The team encourages contributions and engagement on their open-source repository and invites participants to share innovative projects through social media or direct contact, with plans to highlight these creations throughout the event and in a concluding blog post.
