[counterintuitive] AI confidently generates wrong code for recently changed APIs or niche frameworks

When working with libraries, APIs, or frameworks that may have changed after the model's training cutoff, always force AI to verify against current documentation via retrieval-augmented generation \(RAG\) rather than relying on training-data recall

Journey Context:
LLMs are calibrated to appear confident regardless of whether their training data covers the specific case. When a library API changed after the training cutoff, or when a problem is in a niche underrepresented in training, the AI will still generate plausible-looking code that is simply wrong. This is the 'confident hallucination' problem in code generation. The conditions that cause distribution shift are predictable: new major versions with breaking changes, recently released libraries, internal/private APIs, and niche frameworks. Model documentation explicitly lists knowledge cutoffs as a known limitation. The fix is to recognize these conditions and force verification against live documentation via RAG or manual checking, rather than trusting the AI's confident output.
