Observability is a crucial component in the efficient operation of LLMOps, as it allows for the monitoring and optimization of processes across the entire value chain, from training foundation models to agentic networks. Training large language models is particularly resource-intensive and expensive, necessitating fine-grained observability to prevent costly failures and optimize GPU usage. As systems scale, the complexity of observability increases, especially with Retrieval Augmented Generation (RAG) systems and the distributed nature of agentic networks, which require advanced tracing capabilities to monitor the interactions between various components. Current observability tools are evolving to meet these demands, although fully addressing the complexities of agentic networks remains a work in progress. Neptune.ai plays a significant role in this field by offering tools to track and visualize metrics, aiding in the debugging and stabilization of model training.
