[counterintuitive] Is prompt engineering obsolete with better models

Invest in robust prompt engineering and structured outputs; as models become more capable, precise prompting becomes more critical to constrain outputs to exact schemas and reduce ambiguity.

Journey Context:
Developers think 'if the model was smart enough, I wouldn't have to prompt it well.' But software integration requires determinism, specific formats \(JSON, XML\), and strict boundaries. As models get smarter, they generate more plausible but unstructured text. Prompt engineering is actually interface programming—defining the API contract between software and the LLM—not just 'tricking' a dumb model into behaving.
