Lessons from Building Evals for Financial AI Agents

Evaluating local LLM deployments remains one of the most underexplored challenges in the ecosystem. Primer's three-year journey building evaluation frameworks for financial AI agents provides battle-tested patterns applicable to anyone deploying models in production environments. Their insights on designing meaningful benchmarks, measuring real-world performance, and iterating on model behavior without ground-truth labels are invaluable for practitioners moving beyond simple proof-of-concepts.

For teams running self-hosted LLMs in production, robust evaluation is critical—you can't rely on closed-model API feedback or vendor-supplied metrics. Understanding how to benchmark agent behavior, detect degradation, and systematically improve performance through targeted evaluation data is essential for maintaining service quality and making infrastructure investment decisions. The financial domain adds complexity around factual accuracy, consistency, and risk tolerance that mirrors challenges in other high-stakes deployments.

Primer's detailed breakdown is available at their blog, offering practical frameworks for structuring your own evaluation pipelines regardless of model size or deployment target.
