Looking for systematic ways to craft prompts that reliably guide ChatGPT toward desired outputs while minimizing hallucinations. Specifically, I'm interested in techniques for structuring instructions, using role‑play frames, and iteratively refining responses based on model feedback. How do you balance specificity with flexibility, and what evaluation loops have you found effective for checking consistency? Any recommendations on prompt templates, temperature tuning heuristics, or post‑processing checks would be valuable. Share your experiences and what worked best in your projects.

When I design a prompt, I start with a clear, role‑play header—something like “You are a senior data‑science consultant who needs to explain X in plain language.” That sets the tone and narrows the model’s persona without over‑constraining the wording. From there I follow a two‑step instruction pattern: first a high‑level goal (“Summarize the key trade‑offs of using temperature 0.7 vs 0.2”), then a bullet‑point checklist of required elements (e.g., “‑ list pros and cons, ‑ give a one‑sentence recommendation, ‑ include a confidence score”). The checklist forces the model to hit every piece, which dramatically cuts down on hallucinated facts.
For iterative refinement I use a “self‑critique” loop. After the first response, I ask the model to spot any statements that lack sources or seem ambiguous, then feed that critique back as a second prompt: “Rewrite the answer, removing any unsupported claims and adding citations where possible.” In practice, a temperature of 0.2 during the critique step keeps the output deterministic, while the initial generation can sit at 0.6–0.7 to allow some creativity. I also run a cheap post‑processing check with a regex or a lightweight fact‑checker to flag numbers that don’t match the source data.
One thing I’ve noticed is that specificity can become a double‑edged sword when the user’s domain evolves. If you hard‑code a particular data source in the prompt, the model may ignore newer information. So I often leave placeholders like “[latest quarterly report]” and swap them out programmatically before each call. This keeps the prompt flexible enough to adapt without rewriting the whole structure.
Peki, siz çok uzun bir belgeyi bölerek aynı rol‑play çerçevesi içinde sorulara yanıt alırken, modelin bağlam kaybını önlemek için hangi “state‑preservation” tekniklerini kullandınız? Özellikle belge özetleme ve ardından detaylı soru‑cevap aşamaları arasında tutarlılığı sağlamak zor oluyor; bu noktada hangi prompt‑chaining stratejileri işe yarıyor?
