Is it the model or my prompt that causes vague answers?

Usually the prompt. Newer models reduce some vagueness on their own, but they still cannot supply context you never gave them. If two people send the same model very different prompts, they get very different answers, which points at the input, not the model.

Does telling ChatGPT to "be more specific" fix it?

Sometimes, but it spends a message and still leaves the model guessing at the specifics you have in mind. Putting the audience, format, and goal into the prompt itself is more reliable than asking the model to invent them.

Which details remove the most vagueness?

Audience, desired format, and the purpose behind the request tend to matter most. Those three tell the model who to write for, what shape the answer should take, and what counts as a good result.

ChatGPT vague answers, explained

Why does ChatGPT give vague answers?

Updated June 10, 2026

Quick answer

A vague answer almost always traces back to a vague prompt. When you leave out the audience, the format, or the specific outcome you want, ChatGPT fills the gaps with safe, general text. The fix is to add those details before you send. GPT Master's Prompt Optimizer reads your draft, works out what is missing, and rewrites it into a sharper version you can read next to your original.

You ask a question, get back four paragraphs that could apply to anyone, and spend the next three messages dragging the model toward what you actually wanted. The model is not being lazy. It answered the prompt you sent, which left most of the important choices up to it.

1

Read your prompt back and find the blanks

Before you send, reread the prompt as if you were the one answering it. Who is this for? What should the output look like? What would make it wrong? If those answers are not on the page, ChatGPT has to guess at them, and a guess is where the vagueness comes from.

Fill the blanks in yourself first

Add the audience ("for a non-technical manager"), the format ("a five-line summary"), and the goal ("so they can approve the budget"). This manual fix works, but it requires you to manually draft, format, and review your prompt every single time. It relies entirely on your memory and patience.
