    Eval Set Drift: How to Know When Your Golden Set Went Stale

    The author discusses two common challenges in managing LLM applications: eval set drift and per-customer cost reporting. For eval set drift, they propose using Maximum Mean Discrepancy (MMD) on embeddings to detect when evaluation datasets no longer represent production data. For cost reporting, they suggest leveraging OpenTelemetry baggage to propagate customer IDs across services, avoiding costly pipeline rearchitectures. AI

    Eval Set Drift: How to Know When Your Golden Set Went Stale

    IMPACT Provides practical techniques for developers to improve LLM evaluation accuracy and cost management, crucial for operationalizing AI applications.

    How to Evaluate LLM Output Quality Programmatically

    This article outlines a practical, multi-layered framework for programmatically evaluating the quality of Large Language Model (LLM) outputs. It emphasizes defining specific quality dimensions such as correctness, format compliance, safety, and consistency based on the use case. The framework includes deterministic checks for immediate failure detection and semantic similarity measures using sentence embeddings for free-form text evaluation. AI

    IMPACT Provides a practical framework for developers to ensure the quality and reliability of LLM integrations in production environments.

    I built a self-hosted RAG system for Journalism — What Production Retrieval Taught Me

    A developer built Atlas, a self-hosted Retrieval-Augmented Generation (RAG) system tailored for journalism, utilizing local models and PostgreSQL with pgvector. The system ingests RSS feeds, embeds content, and provides features like grounded Q&A, claim-level fact-checking, and story brief generation. Key lessons learned include the necessity of hybrid search combining vector and full-text search for news corpora, and the significant performance gains from batch embedding over individual article embedding. AI

    IMPACT Highlights the practical challenges and solutions in deploying RAG for specialized domains like journalism, emphasizing hybrid search and efficient embedding strategies.
