The article shows how real-world agentic AI deployments can blow through budgets because multi-step workflows use 5–30× more tokens per task than simple chatbots. It breaks down four hidden cost layers—LLM inference with re-sent context, context rot, tool orchestration, and infrastructure—and offers strategies to curb runaway spending before your production bill arrives.

The article compares OpenAI’s Codex “Oracle” approach—using server-side compaction to maintain a single coherent thread—with Anthropic’s Claude “Firm” method of delegating tasks to multiple sub-agents. It breaks down trade-offs in cost, speed, coherence, and memory loss, and predicts a future hybrid of both strategies.

The article outlines five critical trends reshaping the role of data engineers as AI evolves into a more integrated and operational force by 2026. Emphasizing the need for unified data and AI infrastructures, it highlights the shift from data quantity to quality, the importance of real-time processing, and the necessity of handling multimodal data. Data engineers are urged to adapt their skills to build context-aware systems that can support the demands of AI agents.
