How BlackRock Builds Custom Knowledge Apps at Scale — Vaibhav Page & Infant Vasanth, BlackRock
Overview
BlackRock has developed a framework to accelerate the creation of custom AI and knowledge applications at scale within their asset management operations. This system addresses the complexities of data extraction, LLM strategy selection, and deployment challenges, aiming to reduce app development time from months to days by empowering domain experts.
Who should watch
- AI Engineers and Builders
- Product Managers
- Teams building internal AI tools
- Those facing challenges with prompt engineering and LLM strategy selection
- Organizations needing to deploy AI applications in regulated environments
Key takeaways
- BlackRock's framework consists of a "sandbox" for domain experts to build and refine extraction templates and an "app factory" for deploying these applications.
- The sandbox allows for detailed configuration of extraction fields, including data types, sources, required status, inter-field dependencies, and validations.
- A significant bottleneck in AI app development is prompt engineering, requiring extensive iteration and version management, especially for complex financial instruments.
- Selecting the appropriate LLM strategy (e.g., RAG, chain-of-thought) is crucial and varies based on document complexity and size, with challenges arising from context limitations.
- Deployment involves traditional infrastructure concerns alongside AI-specific needs like choosing appropriate inference clusters (e.g., GPU-based or burstable).
- The framework aims to streamline the process by federating pain points like prompt creation and LLM strategy selection to domain experts, significantly speeding up iteration.
- Human-in-the-loop design is critical, especially in regulated financial environments, to ensure compliance and accuracy through a four-eyes check.
- The return on investment (ROI) must be carefully evaluated, as building custom AI apps can sometimes be more expensive than using off-the-shelf products.
Notable quotes
*Building apps and pushing out these apps relatively quickly is of utmost important to us.*
*The big challenges with scale are again these three categories: prompt engineering, LLM strategies, and deployment.*
*Design for human in the loop first if you're in a highly regulated environment.*
