ChatGPT's answers vary greatly depending on how you ask the question.
When you're not sure exactly what you're asking or need to explain a complex situation, try using the 'Meta Prompt' method.
A meta prompt is a way to first ask ChatGPT the question, “What should I ask you?”
By starting to organize your questions with ChatGPT, you can have deeper, richer conversations.
This method is more effective when the topic is still unclear.

Example is a way to guide ChatGPT to generate the desired answer more accurately by providing one or more examples.
This method helps the model easily identify the desired pattern, style, or type through prompts.
ChatGPT can better understand the intent of a task and generate accurate responses through provided examples.
Providing step-by-step instructions like this allows ChatGPT to clearly execute each step, delivering the user's desired results with higher quality.

To effectively utilize ChatGPT, it's crucial to understand its limitations.
One of the most representative problems among them is hallucination.
Hallucination is a phenomenon in which AI creates non-existent or incorrect information as if it were fact.
For example, this includes making up information that is not in the document without any basis, or making a simple numerical comparison incorrectly.
Hallucinations occur particularly frequently in mathematical calculations, number crunching, and fact-based knowledge creation.
It can be divided into five representative types.

Why should we look at the mean, median, and mode together? It's difficult to grasp the overall picture of the data with just one statistic.
The average is a good indicator of the overall level, but it is greatly influenced by extreme values, such as very high sales or a small number of high-spending customers.
Conversely, the median is less sensitive to these outliers and reliably indicates the midpoint of the actual data.
The mode clearly indicates the most common value in the data, revealing the most frequently experienced situations or patterns.
Below is an example of a ChatGPT prompt that allows you to easily check the mean, median, and mode using real data.

SEO (Search Engine Optimization) is the process of optimizing a site or article so that your content is easily visible on search engines like Google.
Studies show that over 90% of Google search traffic stays on the first page, with less than 5% of users making it to the second page.
Therefore, if you use SEO well, more readers will be able to read your writing.

Why create such a fictional character? Because the most important goal of marketing is to "deliver the right message to the right customer."
A vague demographic classification like ‘women in their 20s and 30s’ may not be enough.
Truly effective planning is only possible when we understand consumers' thoughts, feelings, and behaviors.
Personas also serve as a reference point for setting direction when planning products or creating content.
Because you can judge questions like “Who is this article for?” and “Is this feature really necessary?” from the perspective of the established persona, rather than making vague guesses.
Personas are a key tool that enables "customer-centric thinking" in all processes, including marketing planning, content creation, and communication strategy.

ChatGPT Agent Mode is a feature that allows ChatGPT to 'act' on its own and perform multi-step tasks.
While the general chat GPT conversation mode is a question-and-answer format, the agent mode acts like a business agent, solving complex requests.
According to OpenAI's official announcement, ChatGPT, with agent mode enabled, can handle any task a user wants from start to finish, leveraging multiple tools, including web searches, code execution, slide and spread creation, in-depth analysis, and external application integration.
