Frequently Asked Questions
Q: Is it still possible to build simple AI apps in 2026?
A: Yes, for low-stakes, internal tools, or consumer apps where errors are acceptable. However, for enterprise applications involving data, money, or safety, the complexity is unavoidable. The "simple stack" is viable only for non-critical use cases.
Q: How do I handle the cost of LLM inference?
A: Implement a multi-model routing strategy. Use smaller, cheaper models for simple tasks and larger, more expensive models for complex reasoning. Use caching to avoid re-processing identical queries. Monitor costs in real-time and set budgets.
Q: What is the most important skill for an AI engineer in 2026?
A: System design and observability. Knowing how to build a resilient, cost-aware architecture that can handle the non-determinism of LLMs is more valuable than knowing how to prompt a specific model. Understanding the infrastructure and the economics is key.
