"Your embeddings are out of sync again."It's a message that haunts engineering teams trying to build AI applications. What starts as a simple vector search implementation inevitably evolves into a complex orchestra of monitoring, synchronization, and firefighting.We've spent the past year talking to dozens of engineering teams building AI systems with vector databases, whether semantic search, retrieval-augmented generation (RAG) systems, or AI agents. We learned that while everything works smoo...
