Why AI Engineering Is Becoming More Like Distributed Systems Engineering

According to the article, AI engineering is increasingly resembling distributed systems engineering as foundation models improve, with the primary challenges shifting from the models themselves to surrounding infrastructure. Key concerns include orchestration, retries, queues, workflow state, observability, evaluation, and scaling, as production AI workflows involve retrieval, multiple LLM/tool calls, async processing, validation, and downstream systems. The article concludes that engineers are now tackling classic system problems rather than focusing solely on prompting.

As foundation models continue to improve, I think AI engineering is starting to look far more like distributed systems engineering. The difficult part usually is not the model itself - it is everything around it: - Orchestration - Retries - Queues - Workflow state - Observability - Evaluation - Scaling A production AI workflow can very quickly become: - Retrieval - Multiple LLM/tool calls - Async processing - Validation - Downstream systems At that point, you are dealing with classic system problems rather than just prompting.
