Prompt Engineering Is Dead: What Matters in 2026
The prompt engineering they sold you is dead. The magic incantations stopped mattering. What matters in 2026 is diagnosing how the model fails. No fluff.

Taxonomy of LLM failures
Language models fail in four distinct ways. Each requires a different fix: prompt tuning, RAG, fine-tuning, or guardrails. A practical taxonomy.
The model knows how to reason. It just won't commit
17 prompt iterations revealed that the model finds the correct answer but self-censors for not being standard

3 Coins, Tails Always Even: Is It 0 or 1/13?
P(heads)=1/3, number of tails is always even. Is P(all heads) 0 or 1/13? Both are valid — full math, why AI always picks wrong, and how to fix it.
Why LLMs Reject Their Own Correct Answers
Two-Box separates contexts so the LLM reviews without bias. Problem: counterintuitive answers get discarded.
