Make your LLM app a Domain Expert: How to Build an Expert System — Christopher Lovejoy, Anterior
Christopher Lovejoy , Anterior
Overview
This talk outlines a playbook for building domain-native LLM applications, emphasizing that the system surrounding the model is more critical than the model's sophistication itself. The core challenge, termed the "last mile problem," involves providing LLMs with specific contextual understanding of industry workflows. By developing an adaptive domain intelligence engine, companies can leverage domain experts to translate industry insights into performance improvements, enabling continuous iteration and refinement of AI applications.
Who should watch
- AI engineers and builders focused on vertical AI applications.
- Product Managers seeking to improve LLM application performance in specialized domains.
- Teams struggling with the "last mile problem" of applying LLMs to specific industry contexts.
- Those interested in creating self-improving, data-driven AI systems.
Key takeaways
- The system for incorporating domain insights is more crucial than model sophistication for vertical AI applications.
- The "last mile problem" refers to providing LLMs with specific workflow and industry context.
- An adaptive domain intelligence engine, comprising measurement and improvement components, is key to enhancing performance.
- Defining user-centric metrics and creating a failure mode ontology, ideally led by domain experts, are critical measurement steps.
- Failure mode labeling generates production-representative datasets for targeted iteration and performance improvement.
- Domain experts can be integrated into the improvement loop by suggesting changes and new domain knowledge through bespoke tooling.
- This iterative process allows for rapid fixes and deployment of improvements, leading to significant accuracy gains.
- The ultimate goal is a self-improving, data-driven process managed by a domain expert product manager.
Notable quotes
*The system that you build for incorporating your domain insights is far more important than the sophistication of your models and your pipelines.*
*The limitation these days is not like how powerful is your model and whether it can reason to the level you need it to. It's more can your model understand the context.*
*To build a domain native element application you need to solve the the last mile problem.*
