The Observe plugin is an OpenAI plugin that provides LLM observability, allowing users to analyze and understand their data. The plugin was built in under 24 hours by a team at Arize AI and consists of several components, including the API, manifest file, and OpenAPI specification. These components work together to provide a user-friendly interface for exploring and visualizing data, as well as generating summaries and clustering similar data points. The plugin uses GPT-4's chat completion API to perform tasks such as summarization and sentiment analysis, and can be integrated with existing APIs and applications. However, the team notes that there are challenges ahead, including improving context management practices and scaling the solution to larger clusters with longer text.
