As organizations increasingly adopt LLMs for AI-powered applications such as content creation, Retrieval-Augmented Generation (RAG), and data analysis, SREs and developers face new challenges. Tasks like monitoring workflows, analyzing input and output, managing query latency, and controlling costs become critical. LLM observability helps address these issues by providing clear insights into how these models perform, allowing teams to quickly identify bottlenecks, optimize configurations, and improve reliability. With better observability, SREs can confidently scale LLM applications, especially on platforms like Google Cloud Vertex AI
Observability needs for AI-powered applications using Vertex AI
Leveraging AI models creates unique needs around the observability and monitoring of AI-powered applications. Some of the challenges that come with using LLMs are related to the high cost to call the LLMs, the quality and safety of LLM responses, and the performance, reliability and availability of the LLMs.
Lack of visibility into LLM observability data can make it harder for SREs and DevOps teams to ensure that their AI-powered applications meet their service level objectives for reliability, performance, cost and quality of the AI generated content and have enough telemetry data to troubleshoot related issues. Thus, robust LLM observability and detection of anomalies in the performance of models hosted on Google Cloud Vertex AI in real time is critical for the success of AI-powered applications.
Depending on the needs of their LLM applications, customers can make use of a growing list of models hosted on Vertex AI such as Gemini 1.5 Pro, Imagen for Image Generation, and PaLM 2 for Text. Each model excels in specific areas and generates content in some modalities including Language, Audio, Vision, Code, etc. No two models are the same, each model has specific performance characteristics, and so it is important that service operators are able to track the individual performance, behaviour and cost of each model.
