Level One—Initial: The foundation of exploration
At this foundational stage, organizations embark on a journey of discovery and foundational understanding. The focus is predominantly on exploring the capabilities of pre-built LLMs, such as those offered by Microsoft Azure OpenAI Service APIs or Models as a Service (MaaS) through inference APIs. This phase typically involves basic coding skills for interacting with these APIs, gaining insights into their functionalities, and experimenting with simple prompts. Characterized by manual processes and isolated experiments, this level doesn’t yet prioritize comprehensive evaluations, monitoring, or advanced deployment strategies. Instead, the primary objective is to understand the potential and limitations of LLMs through hands-on experimentation, which is crucial in understanding how these models can be applied to real-world scenarios.
At companies like Contoso1, developers are encouraged to experiment with a variety of models, including GPT-4 from Azure OpenAI Service and LLama 2 from Meta AI. Accessing these models through the Azure AI model catalog allows them to determine which models are most effective for their specific datasets. This stage is pivotal in setting the groundwork for more advanced applications and operational strategies in the LLMOps journey.
Level Two—Defined: Systematizing LLM app development
As organizations become more proficient with LLMs, they start adopting a systematic method in their operations. This level introduces structured development practices, focusing on prompt design and the effective use of different types of prompts, such as those found in the meta prompt templates in Azure AI Studio. At this level, developers start to understand the impact of different prompts on the outputs of LLMs and the importance of responsible AI in generated content.
An important tool that comes into play here is Azure AI prompt flow. It helps streamline the entire development cycle of AI applications powered by LLMs, providing a comprehensive solution that simplifies the process of prototyping, experimenting, iterating, and deploying AI applications. At this point, developers start focusing on responsibly evaluating and monitoring their LLM flows. Prompt flow offers a comprehensive evaluation experience, allowing developers to assess applications on various metrics, including accuracy and responsible AI metrics like groundedness. Additionally, LLMs are integrated with RAG techniques to pull information from organizational data, allowing for tailored LLM solutions that maintain data relevance and optimize costs.
For instance, at Contoso, AI developers are now utilizing Azure AI Search to create indexes in vector databases. These indexes are then incorporated into prompts to provide more contextual, grounded and relevant responses using RAG with prompt flow. This stage represents a shift from basic exploration to a more focused experimentation, aimed at understanding the practical use of LLMs in solving specific challenges.
Level Three—Managed: Advanced LLM workflows and proactive monitoring
During this stage, the focus shifts to refined prompt engineering, where developers work on creating more complex prompts and integrating them effectively into applications. This involves a deeper understanding of how different prompts influence LLM behavior and outputs, leading to more tailored and effective AI solutions.
At this level, developers harness prompt flow’s enhanced features, such as plugins and function callings, for creating sophisticated flows involving multiple LLMs. They can also manage various versions of prompts, code, configurations, and environments via code repositories, with the capability to track changes and rollback to previous versions. The iterative evaluation capabilities of prompt flow become essential for refining LLM flows, by conducting batch runs, employing evaluation metrics like relevance, groundedness, and similarity. This allows them to construct and compare various metaprompt variations, determining which ones yield higher quality outputs that align with their business objectives and responsible AI guidelines.
In addition, this stage introduces a more systematic approach to flow deployment. Organizations start implementing automated deployment pipelines, incorporating practices such as continuous integration/continuous deployment (CI/CD). This automation enhances the efficiency and reliability of deploying LLM applications, marking a move towards more mature operational practices.
Monitoring and maintenance also evolve during this stage. Developers actively track various metrics to ensure robust and responsible operations. These include quality metrics like groundedness and similarity, as well as operational metrics such as latency, error rate, and token consumption, alongside content safety measures.
At this stage in Contoso, developers concentrate on creating diverse prompt variations in Azure AI prompt flow, refining them for enhanced accuracy and relevance. They utilize advanced metrics like Question and Answering (QnA) Groundedness and QnA Relevance during batch runs to constantly assess the quality of their LLM flows. After assessing these flows, they use the prompt flow SDK and CLI for packaging and automating deployment, integrating seamlessly with CI/CD processes. Additionally, Contoso improves its use of Azure AI Search, employing more sophisticated RAG techniques to develop more complex and efficient indexes in their vector databases. This results in LLM applications that are not only quicker in response and more contextually informed, but also more cost-effective, reducing operational expenses while enhancing performance.
