According to @AndrewYNg, DeepLearning.AI launched a short course, Building and Evaluating Data Agents, created with Snowflake and taught by @datta_cs and @_jreini, focused on embedding comprehensive evaluation into LLM data agents.

The course teaches the Goal-Plan-Action framework with runtime evaluations to catch failures mid-execution, OpenTelemetry-based tracing and evaluation to pinpoint where agents fail and systematically improve performance, and LangGraph-based orchestration across web search, SQL, and document retrieval for step-by-step visibility—capabilities directly applicable when building data agents used in analytics and trading pipelines.
