How Rubric Labs and Graphite leveraged LLMs to create personalized videos at scale

As 2023 concludes, Rubric's Graphite team aimed to celebrate GitHub users' contributions by creating "Year in Code," an AI-generated, personalized video experience. Unlike previous projects, this initiative utilized LangChain and OpenAI's GPT-4-turbo to transform GitHub user data into unique narratives, moving beyond static images and templated formats. The project employed cutting-edge technologies such as Supabase for authentication and data storage, Remotion for video creation, and AWS Lambda for video rendering. By focusing on a structured video_manifest and leveraging pre-built scene templates, the team balanced AI creativity with quality control, resulting in engaging and shareable 60-second videos. This open-source project, which emphasizes user privacy by excluding code access, showcases the potential of AI and modern tech stacks in generating immersive and personalized digital experiences.
