I have used CustomGPT for over a year and built more than a dozen custom GPTs with it. I tested every feature here by hand, so this is a real step by step guide, not vendor marketing.

CustomGPT is one of the most useful tools for building your own custom GPT trained on your own 데이터.

Most people only scratch the surface of what a custom gpt can do.

This guide shows you how to use customgpt, feature by feature.

단계별 설명과 스크린샷, 전문가 팁을 함께 제공합니다.

Getting Started with CustomGPT

Before you build custom GPTs, finish this one-time setup.

It takes about three minutes.

Watch my personal walkthrough first:

이제 각 단계를 하나씩 살펴보겠습니다.

1단계: 계정 생성

Go to the CustomGPT website and click Sign Up.

이메일 주소를 입력하고 비밀번호를 만드세요.

If you already have an openai account, the flow will feel familiar.

Verify your email, then pick a plan or start the free trial. You can change plans later as your needs grow, so do not overthink this first choice.

✓ 검문소: 확인하세요 받은 편지함 확인 이메일을 보내드립니다.

2단계: 대시보드를 엽니다.

Log in and open the main dashboard in your browser.

This is your gpts section, where every custom GPT you create will live.

Take a minute to look around. You will see the create button, a list of any existing gpt you have built, and a settings menu in the top right corner. Knowing where things sit now saves clicks later.

대시보드는 다음과 같습니다.

✓ 검문소: You should see the main dashboard and a create button.

Step 3: Set Your Profile and Defaults

Add a profile picture and set your default language and time zone.

These small defaults shape how every custom chatbot you build will respond to a user.

If you plan to share GPTs publicly, a clear profile picture and name build trust. People are more likely to try a tool that looks maintained by a real business.

How to Use CustomGPT AI Agent Builder

일체 포함 에이전트 빌더 lets you build your own custom GPT and custom chatbot without writing a single line of code.

The AI Agent 건축업자 is where you create a custom GPT from scratch. It hides the messy parts of the underlying LLMs so any user can build custom GPTs in minutes. You bring the data, and CustomGPT handles the base model, the prompt routing, and the chatbot’s behavior. If you have ever wished you could clone an existing gpt and point it at your own content, this is that moment. You are not coding a generative pre-trained transformer by hand. You are shaping one with plain instructions and a stack of files.

Why does this matter? Because the builder is the gateway to everything else. Get a clean custom GPT here, and the citations, anti-hallucination, and API features all have something solid to work with. Rush it, and every later step inherits the mess.

다음은 단계별 사용 방법입니다.

Step 1: Open the create panel

Log into your account and click create in the top right corner.

The create panel opens a short form. Give your custom GPT a clear name and a one-line purpose. A concise, descriptive name helps users know what the AI does before they type a single prompt. You can also start from an existing gpt template if one is close to your goal, then edit it into your own version. For example, a support bot template saves you from writing every instruction from a blank page.

Step 2: Provide instructions and data

Add your knowledge files or paste a website link, then write your initial instructions.

This is the heart of creating custom GPTs. Upload knowledge files such as PDFs, docs, or help articles, then provide instructions that tell the AI how to respond. You can add advanced customizations later in the configure tab, and you can check the different capabilities you want on, such as web browsing or image generation. Custom GPTs can hold up to twenty files, each as large as 512MB, so most teams have plenty of room. Keep your instructions specific. The more precise your gpt instructions, the more predictable the answers.

이것이 어떤 모습인지 보여드리겠습니다.

✓ 검문소: You should see AI Agent Builder active inside your custom GPT.

Step 3: Click create and test

Click the create button, then open the preview panel to test how the AI responds.

Watch how the AI responds to a new prompt. If the answer drifts, tweak your gpt instructions and click update. Continuous improvement comes from this loop of test, feedback, and small edits. Try several real prompts a user might send, not just easy ones. The configure tab keeps your settings, so you can iterate as often as you like until the custom GPT matches what you pictured.

How to Use CustomGPT Anti-Hallucination Technology

환각 방지 기술 lets you make sure the AI responds only from your knowledge base instead of guessing.

A large language model can invent facts. Anti-Hallucination Technology stops that. It forces your custom GPT to respond only from the knowledge base you upload, so the AI does not make things up. For a business answering customer inquiries, that accuracy is the difference between trust and a refund request. A normal chatbot guesses when it does not know. This one says it does not know, which is exactly what you want when your name is on the answer.

Why does this matter? A single made-up answer can cost a sale or a customer. This feature is the safety net that lets you put a custom chatbot in front of real users without watching it every minute. It is the reason teams trust the tool with live customer inquiries.

다음은 단계별 사용 방법입니다.

Step 1: Build a clean knowledge base

Upload knowledge files that hold the correct answers, and remove old or wrong documents.

The AI responds from what you feed it, so the knowledge section is your source of truth. Keep the data clean. If two files disagree, the AI may pick the wrong one when it tries to answer questions. For example, an outdated pricing sheet sitting next to a current one will confuse the bot. Delete the old version. A tidy knowledge base is the single biggest lever on accuracy, far more than the base model behind it.

Step 2: Set strict instructions

In the configure tab, write specific instructions telling the AI to answer only from your data.

Add a line like respond only from the uploaded knowledge files, and say I do not have that information when unsure. These gpt instructions shape the chatbot’s behavior far more than the base model alone. You can also tell the AI to ask a clarifying 질문 instead of guessing. Small wording changes here have a big effect, so treat your instructions as something you fine tune over time, not set once and forget.

이것이 어떤 모습인지 보여드리겠습니다.

✓ 검문소: You should see Anti-Hallucination Technology active inside your custom GPT.

Step 3: Test edge cases

Ask tricky questions in the preview panel and confirm the AI stays inside your knowledge base.

Throw odd prompts at it. If the AI invents an answer, tighten your instructions and click update. Testing is critical after you fine tune, and small changes can significantly enhance accuracy. Try questions your data does not cover and confirm the bot admits the gap. A custom GPT that knows its limits earns more trust than one that always has an answer.

How to Use CustomGPT Real-Time Source Citations

Real-Time Source Citations lets you show readers exactly where each answer came from inside your knowledge section.

When the AI responds, Real-Time Source Citations show exactly which document the answer came from. Users see a link back to the source, which builds trust and lets them dig deeper. For any business, citations turn a black-box answer into a checkable one and quietly enhance customer engagement. People believe an answer more when they can see where it came from, and your support team spends less time defending the bot’s replies.

Why does this matter? Trust is everything in support. When a user can click through to the exact page behind an answer, they stop second-guessing the bot. Citations also help you, because they show at a glance which knowledge files the AI leans on most.

다음은 단계별 사용 방법입니다.

Step 1: Turn on citations

In advanced settings, enable source citations so every answer links back to your data.

Citations are part of the advanced customizations CustomGPT offers. Once on, each reply your AI generates includes a link to the exact file or page, straight from your knowledge section. This is one of the different capabilities that sets CustomGPT apart from a plain chatbot. The link is live, so a user can click through and read the full context behind any answer.

Step 2: Tag your knowledge files

Give each uploaded file a clear title so citations read cleanly for the user.

A file named refund-policy-2026 makes a better citation than document-final-v3. Clean names in your knowledge base make the AI 도구 feel more like a useful tool and less like a guess. For example, naming files by topic and date helps both the AI and the reader. Tidy titles also make it easier for you to spot which document needs an update later.

이것이 어떤 모습인지 보여드리겠습니다.

✓ 검문소: You should see Real-Time Source Citations active inside your custom GPT.

Step 3: Review cited answers

Open the preview panel, ask questions, and click each citation to confirm it points to the right data.

Click a citation and confirm the source backs the answer. If a link is wrong, fix the file and click update. This process keeps your custom GPT honest as your data grows. Run this check whenever you add new knowledge files, because a fresh document can change which source the AI cites for a common question.

How to Use CustomGPT Free Sitemap Tools

Free Sitemap Tools lets you pull a whole website into your knowledge base from a single link.

You do not have to upload files one by one. The Free Sitemap Tools pull an entire website into your knowledge base from a single link. Paste your domain, and CustomGPT crawls the pages and turns them into data your custom GPT can answer questions from. It is the fastest way to feed a custom chatbot real content. Instead of copying help articles by hand, you point the tool at your site and let it do the heavy lifting in one pass.

Why does this matter? Setup speed decides whether a project ships or stalls. Most people give up when feeding data feels like a chore. Pulling a whole site in from one link removes that friction, so your custom GPT goes from empty to useful in a single afternoon.

다음은 단계별 사용 방법입니다.

Step 1: Generate a sitemap

Open the sitemap tool and paste your website link to map every page.

The tool reads your site and lists the pages it found. This is free, and it saves hours versus copying content by hand into knowledge files. For example, a help center with two hundred articles imports in minutes instead of a week. The map also shows you pages you may have forgotten existed, which is a handy 심사 on its own.

Step 2: Select pages to import

Pick which pages become part of your knowledge base, then start the crawl.

Skip thin or duplicate pages. Choose help docs, product pages, and FAQs so the AI responds with the content that actually answers questions for your users. Leaving out low-value pages keeps your knowledge base sharp. A smaller, focused set of pages almost always produces better answers than dumping in the entire site.

이것이 어떤 모습인지 보여드리겠습니다.

✓ 검문소: You should see Free Sitemap Tools active inside your custom GPT.

Step 3: Confirm the import

Wait for the crawl to finish, then click update to refresh your knowledge section.

Once the import lands, open the preview panel and test a prompt. Your custom GPT now draws on the whole site, and you can re-crawl any time content changes for continuous improvement. Set a reminder to re-run the crawl after major site updates, so your custom chatbot never quotes a page you have already rewritten.

How to Use CustomGPT Powerful APIs

Powerful APIs lets you connect your custom GPT to any app and drive AI 오토메이션 behind the scenes.

Once your custom GPT works, the Powerful APIs let you put it anywhere. Connect the custom chatbot to your website, app, or internal tools, and drive AI 오토메이션 that runs without you. This is where a custom GPT stops being a demo and starts to perform tasks for real users at scale. The API exposes the same trained model you built in the dashboard, so the answers stay grounded no matter where the question comes from.

Why does this matter? A custom GPT trapped in a dashboard helps no one. The API is what lets it meet users where they already are: your site, your app, your helpdesk. This is the step that turns a neat demo into real AI automation your business runs on.

다음은 단계별 사용 방법입니다.

Step 1: Grab your API key

Open advanced settings and copy the API key for your custom GPT.

The key links your code to the AI. Keep it private. Anyone with this key can send a prompt to your custom chatbot and get a response back. Store it in an environment variable, not in your front-end code. Treat the key like a password, because it controls access to the AI you spent time building.

Step 2: Send a test request

Use the sample code to send a prompt and read the AI response in your app.

Drop the snippet into your code, send an input, and the API returns the answer. If you have used a code interpreter or any AI 도구 before, this will feel familiar. For example, a simple request sends a question and prints the reply, which is enough to confirm the connection works before you build anything bigger.

이것이 어떤 모습인지 보여드리겠습니다.

✓ 검문소: You should see Powerful APIs active inside your custom GPT.

Step 3: Wire it into your product

Connect the API to your chat widget, helpdesk, or workflow to perform tasks live.

Now your custom GPT answers customer inquiries inside your own product. Pair it with other AI tools for full AI automation, and your team handles fewer repetitive tasks. You can route different questions to different agents, log every prompt for feedback, and build your own version of a support flow that runs day and night without a human on call.

Who Should Use CustomGPT

Custom GPTs are best for repetitive, specialized work where you would otherwise repeat the same context again and again.

• Support teams drowning in repeat customer inquiries: A custom chatbot answers the same questions all day, so your team handles the hard cases and you enhance customer engagement at the same time.
• Course creators and consultants who want their own gpt: Upload your knowledge files, and the AI responds to students with your 목소리, not a generic base model.
• Marketers who want AI automation without code: The gpt builder lets you create a custom gpt, add conversation starters, and ship it as a link in an afternoon.
• Developers who need data-grounded answers: The powerful APIs let you connect a custom GPT to any product and perform tasks at scale, with anti-hallucination keeping replies honest.
• Any business that wants tailored setups for specific needs: Multiple custom GPTs can run for different tasks, each trained on its own knowledge base.

If your work involves answering questions from a fixed body of data, a custom GPT is a valuable tool that pays for itself fast.

It is less useful if your questions are wildly open-ended or change every day. In that case the AI has no stable knowledge base to lean on, and a general assistant may serve you better.

But for the common pattern, the same questions, the same data, day after day, a custom chatbot is hard to beat. It turns repetitive work into a quick prompt and a grounded reply.

CustomGPT Pro Tips and Shortcuts

After building custom GPTs with CustomGPT for over a year, here are my best tips.

None of these need code. They are habits and shortcuts that make the gpt builder faster and your answers sharper, whether you are on your first GPT or your fiftieth.

워크플로 바로가기

대부분의 사람들이 놓치는 숨겨진 기능들

• Conversation starters: Add conversation starters in advanced settings so users know how to open a chat. Good starters significantly enhance how many people actually use your gpt.
• Refine with AI: Ask the AI to rewrite your gpt prompts for clarity. A cleaner new prompt gives sharper answers without you touching the base model.
• Multiple agents: Build custom GPTs for different tasks instead of one giant bot. A focused custom gpt for sales and another for support beats a single confused one.

CustomGPT Common Mistakes to Avoid

Mistake #1: Dumping in too much data

Mistake #2: Writing vague instructions

Mistake #3: Skipping testing

CustomGPT Troubleshooting

Problem: The AI gives wrong or made-up answers

원인: Your knowledge base has gaps, or your instructions are too loose, so the AI fills the blanks itself.

고치다: Add the missing data, then write instructions telling the AI to answer only from your knowledge files. Click update and test again in the preview panel.

Problem: The sitemap crawl misses pages

원인: Some pages are blocked by your robots file or sit behind a login the crawler cannot reach.

고치다: Open your sitemap link and confirm the pages are public. Add them by URL one by one if needed, then re-run the import to refresh your knowledge section.

Problem: My API request returns an error

원인: The API key is wrong, expired, or missing from your request header.

고치다: Copy a fresh key from advanced settings and paste it into your code. Send one simple input first to confirm the AI responds before wiring it into your product.

Problem: Citations point to the wrong file

원인: Two documents in your knowledge base cover the same topic, so the AI cites the weaker one.

고치다: Remove or merge the duplicate, give the right file a clear title, and click update. Then re-test the prompt to confirm the citation now points to the correct data.

Problem: The GPT is slow to answer

원인: Your knowledge base is very large, or you turned on capabilities you do not need, so each prompt takes longer to process.

고치다: Trim files you no longer use and turn off extra capabilities in advanced settings. A leaner setup answers questions faster and costs less to run at scale.

Problem: My shared link does not work for others

원인: The sharing settings are still set to private, or the GPT sits behind a plan that the viewer cannot access.

고치다: Open sharing settings and switch to link access or public. Confirm the link is the current one, then send it again. Anyone with the link should now reach the GPT.

Problem: Conversation starters do not show up

원인: The starters field was left blank, or you saved the draft without clicking update, so the create panel never stored them.

고치다: Open the configure tab, add your conversation starters one per line, and click update. These short prompts guide users on how to interact with your GPT, so add three or four that match common customer inquiries.

Problem: The AI ignores my custom instructions

원인: Your initial instructions are vague, or they conflict with the conversation starters, so the base model falls back on its own defaults.

고치다: Rewrite the gpt instructions with specific, detailed rules and remove anything that contradicts them. Small changes in instructions can significantly improve performance, so test each edit in the preview panel before you click update.

📌 메모: If none of these fix your issue, contact CustomGPT support.

CustomGPT란 무엇인가요?

커스텀GPT is a gpt builder that lets you create a custom gpt trained on your own data, with no code.

Think of it like a smart assistant that has read all your documents and can answer questions about them on demand.

A generative pre-trained transformer powers it, but you never touch the underlying llms directly.

The whole point is to remove the need to repeatedly provide context. Instead of pasting the same background into every chat, you load it once as knowledge files, and the AI remembers it for every user.

That makes a custom GPT best for repetitive, specialized tasks. A team that answers the same customer inquiries all day gets the most value, because the AI handles the routine and frees people for the hard cases.

It is also a tool you grow into. You can create a custom gpt today and add advanced customizations later, building your own version of a support agent, a sales helper, or an internal knowledge bot.

• Free Sitemap Tools: Pulls a whole website into your knowledge base from one link.
• Powerful APIs: Connects your custom GPT to any app for AI automation.

Custom GPTs remove the need to repeatedly provide context, which is why they are best for repetitive, specialized tasks. For a full review, see our CustomGPT review.

Here is a closer look at what the platform offers:

How Custom GPTs Work

Under the hood, a custom GPT sits on top of a large language model. You never train the base model yourself.

Instead, you give it two things: your data and your instructions. The data is the knowledge files you upload, and the instructions tell the AI how to respond.

When a user sends a prompt, the GPT searches your knowledge base, finds the matching passages, and writes an answer grounded in that data. That is why citations are possible and why hallucinations drop.

You shape the chatbot’s behavior in the configure tab. Here you set the name, the initial instructions, the conversation starters, and the different capabilities you want on.

Those capabilities matter. Web browsing lets the GPT pull up-to-date information when your files fall short. Image generation through DALL·E lets it create images inside a chat. A code interpreter handles math and data tasks. For high-level reasoning, specialized models like o1 do the heavy thinking.

File limits are generous. You can upload up to twenty files, each up to 512MB, which covers most help centers and product libraries with room to spare.

There is also a project feature that creates folder-like environments for your work. Projects help organize ongoing chats and files for a specific task, so a busy team keeps its data tidy across many custom GPTs.

The instructions field has an 8000 character limit, which is plenty for detailed gpt instructions. If you run long, trim the filler and keep the specific rules that shape how the AI responds.

The whole loop is built for continuous improvement. You provide instructions, test in the preview panel, read the feedback, fine tune, and click update. Repeat until the custom GPT meets your desired performance.

Sharing Your Custom GPT

Once your custom GPT works, sharing it is simple. Custom GPTs can be shared easily with others after creation.

Sharing settings decide who can reach your GPT. You choose one of three options: private, link access, or public.

• Private: Only you can use it. Best while you build and test, before anyone else sees the chatbot’s behavior.
• Link access: Anyone with the link can open it, including free users. Great for sharing your own gpt with a client or a team.
• Public: The GPT is listed for anyone to find. For OpenAI custom GPTs, that means the gpt store, where users 먹다 and try community-built tools.

For OpenAI custom GPTs, only 챗GPT Plus users can create and share them. Anyone with a link can then access the shared GPT, even on a free plan, which makes link access a handy way to reach a wide audience.

You stay in control. The creator can remove a custom GPT from the sidebar or change its sharing settings at any time, so a GPT you no longer use does not linger.

This flexibility is part of why custom GPTs are such a valuable tool for a business. You can keep an internal GPT private, hand a client GPT out by link, and push a marketing GPT public, all from one account.

CustomGPT 가격 책정

Here is what CustomGPT costs in 2026:

무료 체험: Yes — you can test the gpt builder before you pay.

환불 보장: Check current terms at checkout, as they change.

Here is the pricing at a glance:

💰 최고의 가성비: Standard — it gives most businesses enough room to build custom GPTs and answer real customer inquiries.

The Standard plan suits a small team shipping its first custom chatbot. You get the gpt builder, knowledge files, citations, and the API, which covers most use cases without paying for scale you do not need yet.

Premium fits a growing business that runs several custom GPTs or handles more data and traffic. The jump in price buys more room, more agents, and higher limits for heavier AI automation.

Enterprise is custom-priced for large companies with security, volume, or compliance needs. If you require single sign-on, data controls, or a high request ceiling, this is the tier to ask about.

For reference, OpenAI custom GPTs need a ChatGPT Plus account, while CustomGPT.ai charges per plan and scales by data and agents.

Whichever plan you pick, start on the lowest tier that fits, then move up only when your data or traffic outgrows it. There is no reason to pay for headroom you will not touch for months.

⚔️ CustomGPT 비교

Here is how CustomGPT stacks up against each competitor:

• CustomGPT와 DocsBot AI 비교: CustomGPT wins on citations and anti-hallucination. DocsBot is cheaper, so pick it if budget matters more than grounded, source-backed answers.
• CustomGPT와 Botpress 비교: CustomGPT is faster to set up with no code. Botpress wins for developers who want full control over the chatbot’s behavior.
• CustomGPT와 Chatbase 비교: CustomGPT offers stronger accuracy and citations. Chatbase is simpler, so beginners may prefer it for a quick custom chatbot.
• CustomGPT와 Tidio 비교: CustomGPT focuses on data-grounded answers. Tidio wins for stores that need live chat plus AI in one place.

CustomGPT는 사용할 가치가 있을까요?

For most teams, yes. A custom GPT removes the need to repeatedly provide context, so the AI answers questions the moment a user asks.

That alone can automate tasks that used to eat hours each week, which improves both efficiency and the user experience.

The real value shows up over time. Because you can fine tune prompts and add knowledge files whenever your data changes, the tool gets better through continuous improvement.

If you only need a single throwaway prompt, a custom gpt is overkill. But if you answer the same customer inquiries again and again, it is a useful tool that earns its keep.

Pair it with other AI tools and a code interpreter for heavier work, and you get a setup tailored to your specific needs.

Think about the math. If a custom GPT deflects even a handful of repeat tickets a day, the hours it saves a support team add up quickly across a month.

There is a learning curve, but it is short. Most people create a custom gpt that works well within an afternoon, then refine it as they read real feedback from users.

The biggest risk is a messy knowledge base, not the price. Spend your effort there, keep the data clean, and the tool rewards you with accurate answers and happy users.

CustomGPT Best Practices

A custom GPT is only as good as the data and instructions behind it. These habits keep yours sharp over time.

• Write one clear purpose: Define what the GPT does and what it ignores. A focused goal keeps the AI on track and makes your custom instructions easier to write.
• Curate, do not dump: Upload only the knowledge files that answer real questions. A lean knowledge base beats a bloated one every time.
• Add conversation starters: Conversation starters guide users on how to open a chat, so they reach a good answer faster and the GPT feels welcoming.
• Refine prompts with AI: Ask the model to rewrite your gpt prompts for clarity. A cleaner new prompt structure often lifts answer quality with zero new data.
• Test, gather feedback, repeat: Iterate your custom GPT until it meets your desired outputs. Continuous improvement is a loop, not a one-time setup.
• Use the right capabilities: Turn on only the different capabilities you need, such as web browsing for fresh data or image generation for visual replies.

Follow these and your custom chatbot keeps getting better as your business and your data grow.

CustomGPT Use Cases and Examples

Here are real ways teams put a custom GPT to work. Each example shows the data you upload and the tasks the AI handles.

• 고객 지원: Upload your help docs and the GPT answers customer inquiries day and night, with citations so users can read the full policy. This alone can deflect most repeat tickets.
• Sales enablement: Feed it your product sheets and pricing, and reps get instant answers during a call instead of digging through files. The GPT becomes a quiet teammate that never forgets a detail.
• Internal knowledge: Point it at your wiki so staff can ask questions and get grounded answers, instead of pinging a colleague for the same thing each week.
• Course delivery: Creators upload lessons and the custom chatbot answers 학생 questions in their own voice, which can significantly enhance how much learners engage with the material.
• Developer docs: Wire the API into your docs site so visitors ask questions in plain language and the GPT replies with a citation, an example, and a link to the exact page.
• 온보딩: Load your policies and process guides, and new hires get instant answers to common questions without waiting on a manager. The GPT acts as a patient guide through their first weeks.
• Research assistant: Upload reports and data sets, then ask the custom GPT to summarize findings or pull a specific figure. With the code interpreter on, it handles the math and returns a grounded answer.

Multiple custom GPTs can run side by side, each trained for a different task, so one tool covers your whole team.

Tips for Writing Better CustomGPT Instructions

Most of a custom GPT’s quality comes from its instructions, not its data. The knowledge files give the AI facts, but the gpt instructions decide how it uses them. A few minutes spent here pays off across every answer your users read.

Start with the purpose. Define what the GPT is for in one plain sentence, then list the tasks it should perform and the ones it should refuse. Specific instructions beat vague ones every time, so name the tone, the format, and the rules the AI responds with.

Tell the AI to answer only from your knowledge base. This single rule keeps replies grounded and cuts guesswork. Pair it with a fallback line, such as asking the user to rephrase when the data does not cover their question, so the chatbot never invents an answer.

Use the preview panel as your test bench. Type a new prompt, read how the AI responds, and adjust the instructions based on that feedback. Small changes in wording can significantly enhance the result, so change one thing at a time and re-test before you click update.

Refine prompts with the AI itself. Ask it to rewrite a rough instruction into a clearer, more structured version, then drop the better wording into the configure tab. This loop of continuous improvement is how a useful tool turns into a valuable tool your whole team trusts.

Keep an eye on the 8000 character limit for instructions. If you run long, trim the filler and keep only the rules that shape the chatbot’s behavior. Lean, specific gpt instructions almost always outperform a wall of 텍스트.
