You are being too vague "Write a marketing plan" gets you generic slop because the model has to guess everything. The fix is specificity: who it is for, what the goal is, and what the constraints are. > You are a head of marketing at a 12-person SaaS startup. Write a 6-week launch plan for a $99/mo product. Include weekly deliverables, an owner, and a KPI for each. Keep it under 400 words. Same model, completely different result. ## 2. You skipped the role and context Models behave differently depending on who you tell them to be. "You are a senior copy editor" produces sharper edits than no role at all. Add the context it needs, too — the audience, the prior decisions, the format of the source material. Without context, the model invents it, and that is where wrong answers come from. ## 3. You didn't specify the output format If you do not say what the output should look like, you get a wall of prose. Specify it as a contract: a table, a bulleted list, JSON, a three-sentence summary. "Return only a markdown table with columns Task, Owner, Due" stops the model from rambling and makes the output something you can actually use. ## 4. You accepted the first draft The first draft is the worst draft. The single highest-leverage move is to make the model critique and improve its own answer: "List three weaknesses of that draft, then rewrite to fix them." It costs a few seconds and almost always improves the result. ## 5. You gave no examples For anything where style or format matters, show — do not tell. Two or three examples that bracket the range you want teach the model faster than a paragraph of instructions. This is the few-shot pattern, and it is the fastest fix for "close, but not quite right." ## Putting it together Most failed prompts break one of those five rules. A reliable opener that covers most of them: **role, goal, context, constraints, and output format** — then a self-critique pass. That structure is the backbone of practical [prompt engineering](/blog/prompt-engineering-patterns). The fastest way to internalise it is reps. Iro AI's [Prompt Lab](/prompt-engineering-app) grades your real prompts and shows you exactly which of these mistakes you are making; the [ChatGPT path](/learn-chatgpt) applies the same moves inside the tool. ## FAQ **Why does ChatGPT give me generic answers?** Usually because the prompt is too vague. Add a role, the goal, context, constraints, and an output format, and the answers get specific fast. **Is it the model's fault or my prompt?** Nine times out of ten it is the prompt. The same model produces very different output depending on how you specify the task. **What is the single best fix?** Ask the model to critique and rewrite its own first draft. It is the highest-leverage move for the least effort. **How do I get better at prompting?** Practice with feedback. Iro AI's Prompt Lab scores your prompts and points out what to fix. ## Read next - [The 7 prompt patterns that work everywhere](https://tryiro.com/blog/prompt-engineering-patterns) - [How to actually learn ChatGPT in 2026](https://tryiro.com/blog/how-to-learn-chatgpt-in-2026) - [How to spot AI hallucinations in 5 seconds](https://tryiro.com/blog/spot-ai-hallucinations) - [Prompt Lab in Iro AI](https://tryiro.com/prompt-engineering-app) ## About the author Alex Furukawa — Founder of Iro AI.
