Six Key Points to Improve the Accuracy of Generative AI Responses

Three years have passed since the arrival of ChatGPT, and generative AI is now used widely—from business to everyday life. Yet many people still say, “I’m not sure I’m using it well” or “I can’t get the answers I want.”

It’s often said that the accuracy of generative AI’s answers “changes dramatically depending on the prompt.” A promptrefers to the questions or instructions given to the AI. If these are vague or imprecise, even the most advanced AI cannot deliver the expected output.

Yoshigi, who shares insights on AI-era career strategy and work techniques on X, explains:

“To get the answers you want from AI, you need to be intentional. There are six major points.”

Let’s take a look (quotes below are from Yoshigi):

1. Assign a role

“Tell the AI something like ‘You are a doctor’ or ‘You are a marketing expert.’ Giving it a clear role or standpoint makes its answers more specific and aligned with that perspective.”

2. Communicate the goal or purpose

“Clearly state what you want to achieve. For example, if you’re launching a new service with no competitors, you might first ask: ‘We’re considering a new sharing-service business. Please research our potential competitors.’ This helps the AI understand what kind of services it should investigate, resulting in clearer answers.”

3. Provide background and context

“For example: ‘I have a briefing for executives next week, so please produce something at an executive-appropriate level.’ Explaining why the information is needed helps AI produce responses suited to the audience.

When I ask AI to draft an outline for a seminar, I always specify the length of the seminar, the target audience, and other contextual assumptions.”

4. Specify the output format

“This is very important. If you say, ‘Give me three career advancement points in bullet form,’ you’ll get bullet points. If you say, ‘Output it in Excel format,’ you’ll get a table-type answer. If you don’t specify, you’ll get plain text.”

Can AI create PowerPoint slides?

“ChatGPT isn’t very good at producing PowerPoint directly. I use Manus, Genspark, and Gemini to create materials—they generate clean slides that export nicely to PowerPoint.”

5. Set constraints

“When asking AI to write an SNS post, you might say: ‘Summarize in 140 characters.’ or ‘Use no more than half as many kanji as hiragana.’ By setting rules or limits, the accuracy improves.”

6. Show examples and give concrete instructions

“If you want good interview reverse-questions, instead of simply saying ‘Give me some reverse questions,’ provide an example:

‘Give me three interview reverse-questions like “Could you tell me about your company’s evaluation system?”’

Concrete examples help the AI understand your intent correctly.”

The key takeaway: AI works best when your instructions are detailed and specific.
“If you give instructions while keeping these six points in mind, the accuracy of the answers will definitely improve,” says Yoshigi.

Give AI instructions step by step

Let’s look at some small tricks and hidden techniques.

When giving instructions to AI, it’s best to do so step by step.

“In other words, give your instructions in a logical sequence. For example, if you want AI to create materials, you might first say, ‘Please research X.’ Next: ‘Based on your research, please create an outline.’ Then: ‘Using that outline, please create the materials.’ You give each instruction one step at a time.”

For instance, if you want to create an SNS post to promote a product, a step-by-step prompt might look like this:

１＿“Please obtain the link to the product.”

2＿“Carefully read the product page you obtained and convert the information into text.”

3＿“Extract the elements of the product that are most likely to go viral and summarize them in a paragraph.”

4＿“Based on that paragraph, create a post within 140 characters.”

“When you give detailed, step-by-step instructions, you’re much more likely to get the kind of answer you had in mind.”

Even a small difference like saying “carefully read it” instead of just read it can change the result.

“Even a single adjective or adverb can significantly change the response. If I want AI to really dig into something, I say so explicitly. For research, I’ll write something like, ‘Please research this thoroughly.’ If I want a candid answer, I’ll add, ‘Please answer without holding back or sugar-coating anything.’ And it really will answer without holding back.”

In other words, AI can also read the room.

“Today’s AI is quite sensitive to the user’s intent and, in a way, is very considerate. Giving an answer that satisfies the user is what success means for AI.”

For business professionals: “Use Deep Research for information gathering”

Yoshigi also works as a consultant at a consulting firm, handling large corporate clients. In what kinds of tasks does he use AI most in his day-to-day work?

“Primarily for research and information gathering. With traditional search engines like Google, it takes time to reach the information you really need, doesn’t it? With AI, you can quickly gather specialized knowledge and case studies related to specific industries.

When I want to do deep research, I use the ‘Deep Research’ features in ChatGPT or Gemini. From the plus button on the text box, you select Deep Research and enter your prompt. Then, over about ten minutes, it reads a large number of web pages and produces a report at the level a consultant would submit.”

Here’s another hidden trick:

“For data analysis, if you attach survey results or other documents to Gemini and then run Deep Research, it will deeply analyze the content of the attachment and produce a report. If you use Gemini’s Canvas feature, it will even visualize the Deep Research results with graphs and other charts and perform analysis, which I think is extremely useful for businesspeople.”
