OpenAI has launched the GPT Store, enabling developers to create and publish custom ChatGPT experiences tailored to specific tasks or domains, such as the Neon PostgreSQL Expert GPT. These custom GPTs, built using Python and Postgres, can include advanced features like web browsing and DALL·E image generation. Developers can enhance these GPTs with Retrieval Augmented Generation (RAG) to access external knowledge bases, though there are limitations, such as a cap on document uploads and concerns about data security. The GPT Store allows creators to monetize their GPTs based on user engagement, but those with extensive knowledge bases or sensitive data might consider building their own RAG applications using open-source tools. Despite these limitations, the GPT Store offers a promising avenue for sharing and monetizing AI innovations with the broader community.
