Can Claude's Sonnet 4 and Opus 4 be used for article creation? Results of my verification

Hello, I am Poke-go, and I research prompts that are useful for article creation.


For a while now, I have been conducting comparative verification of the capabilities of various AIs to see what kind of output they produce during the article creation process.

Comparative verification of persona (target reader) settings
Comparative verification of article outline creation
Comparative verification of title and heading creation
Comparative verification of introduction creation


In the midst of this, it was announced that new models called Sonnet 4 and Opus 4 would be released by Claude.


ChatGPT also announced new models the other day, and I created a verification article for those, but AI really is evolving too fast...😱


In this article, I will verify how the following items, which I was halfway through verifying with the now-outdated 3.7 Sonnet, turn out when generated by Sonnet 4 and Opus 4:

  • Persona settings

  • Article outline creation

  • Title and heading creation

  • Introduction creation

I will verify what happens when these are output by Sonnet 4 and Opus 4.

※ While each model has a standard version and a Thinking model, I am using the Thinking models for all of them this time.


I will use the same prompt as last time to verify the capability differences.

Let's get started right away!




In the case of persona setting

So, first, let's verify the output of the personas set by each model.

Let's look at the first persona output.


Persona set by Sonnet 4

When I entered the prompt into Sonnet 4 and ran it, the output was as follows.

# Persona setting:

Search keyword: "ChatGPT SEO heading creation tips"

## Persona 1:

### 1. Basic information
- Age: 29
- Gender: Male
- Occupation: SEO consultant at a mid-sized web production company (full-time employee)
- Annual income: 4.5 million yen
- Residential area: Setagaya-ku, Tokyo
- Family structure: Single (living alone)
- Economic status: Lives alone in an apartment with 80,000 yen rent. Has some financial leeway but prioritizes investment in skill improvement.

### 2. Situation
- External situation: In charge of SEO for clients at a production company with 50 employees. Handles 10-15 projects in parallel, with tasks like heading creation taking up most of the work. With the advent of ChatGPT, there are signs of change in the industry, and colleagues are discussing AI utilization more often.
- Internal situation: Has extensive basic knowledge of SEO, but feels that "there must be a more efficient way" as he spends time on creating a large number of headings every day. Interested in ChatGPT, but doesn't know how to specifically apply it to SEO and is in a state of trial and error.
- Interaction: The pressure for operational efficiency (external factor) and the expectation for new tools (internal factor) are combining to increase his motivation to "systematically learn the correct way to use ChatGPT."

### 3. Goals, requests, and conflicts
- Goal: To use ChatGPT to streamline the creation of SEO-strong headings and provide higher-quality consulting services.
- Requests: Wants to know specific prompt examples and evaluation criteria, and acquire practical know-how that can be used immediately in actual work. Wants to be able to properly judge the quality of AI-generated headings.
- Conflict: It seems like it would be easier if he used ChatGPT, but he is anxious about whether it really has SEO effects. Since it directly affects client results, he cannot just try it out casually. He is also concerned that if competitors use the same tool, differentiation will become difficult.

### 4. Needs and insights
- Explicit needs: Wants to know how to shorten heading creation time, how to generate headings with high SEO effects, how to design specific ChatGPT prompts, and quality evaluation criteria for generated headings.
- Latent needs: Wants to use AI to perform more creative and strategic SEO consulting, not just for efficiency. Wants to continue producing results that make clients acknowledge him as a "true professional."
- Insight: Has a strong desire for growth, thinking "I want to level up my SEO skills through collaboration with AI, not just efficiency," and recognizes that systematic and proven methodology is necessary for that.

### 5. Behavior
- Behavior change process:
- Trigger: Felt "this is useful" after seeing heading drafts created by a colleague using ChatGPT, but didn't get the results he expected when he tried it himself.
- Changes in emotions/thoughts: Questioned "why is there a difference when it's the same tool?" and became convinced that "there must be a trick to it." Also felt a sense of urgency not to miss the opportunity for operational efficiency.
- Decision-making point: Decided to make time on the weekend to learn how to use ChatGPT for SEO in earnest.
- Episode: On Saturday morning, brewed coffee, sat in front of the PC, and started searching for "ChatGPT SEO heading creation tips."
- Search behavior: Focuses on finding practical prompt examples and success stories. Also searches for "ChatGPT prompt SEO" and "AI heading creation case studies" in parallel to collect systematic information.

Sonnet 4's persona


Persona set by Opus 4

When I entered the prompt into Opus 4 and ran it, the output was as follows.

# Persona setting:

Search keyword: "ChatGPT SEO heading creation tips"

## Persona 1:

### 1. Basic information
- Age: 28
- Gender: Male
- Occupation: Web person in charge at a small-to-medium enterprise (full-time, concurrent position)
- Annual income: 4.2 million yen
- Residential area: Saitama City, Saitama Prefecture
- Family structure: Single (living with parents)
- Economic status: Living expenses are kept low because he lives with his parents, but he is at the stage of saving for self-investment and future independence.

### 2. Situation
- External situation: In charge of web operations concurrently with his main job of sales administration at a manufacturing company with 50 employees for half a year. Responsible for creating about 10 blog articles per month alone. His boss tells him to "get higher search rankings," but there is no specific guidance.
- Internal situation: Thinks he understands the basics of SEO, but feels anxious because the articles he actually created are not ranking higher. In particular, it takes time to create headings every time, and he is not confident that he is creating effective headings. Knows about ChatGPT, but doesn't know how to use it well.
- Interaction: The demand for results from his boss (external factor) and the recognition of his own lack of skills (internal factor) overlap, strengthening his thought that "there must be a more efficient and effective way."

### 3. Goals, requests, and conflicts
- Goal: To be able to efficiently create SEO-strong headings and improve the search ranking of articles.
- Requests: Wants to know specific ways to create headings using ChatGPT. Wants to create high-quality headings without spending time.
- Conflict: Has resistance to relying on AI tools. Doubts whether headings created with ChatGPT are really effective for SEO. Seeking practical methods that can be used immediately while having no time to learn new tools.

### 4. Needs and insights
- Explicit needs: Wants to know specific steps to create headings with ChatGPT, how to write effective prompts, and points for creating headings with SEO in mind.
- Latent needs: Wants to be recognized by his boss and company. Wants to produce results as a web person and prove his own value. Wants to become someone who can master new technology.
- Insight: Seeking both "efficiency" and "results" while having no time due to concurrent duties. While expecting a new tool called ChatGPT, he is carefully looking for methods that will definitely lead to results.

### 5. Behavior
- Behavior change process:
- Trigger: Was shocked to find that the article published last week was ranked below 50th for the target keyword when checking search rankings.
- Changes in emotions/thoughts: From the disappointment of "the ranking isn't going up again," he starts to think "maybe there is a problem with how I make headings." Seeing articles from competitors, he realizes the difference in the quality of headings.
- Decision-making point: Told by his boss at the meeting the next day, "I want you to show me results soon," and strongly feels the need to try a new method.
- Episode: During lunch break, while eating a sandwich at his desk, he remembered "I heard that ChatGPT can be used for writing," and searched for "ChatGPT SEO heading creation tips" on his smartphone.
- Search behavior: Collects a wide range of information, from basic usage to actual application examples. Continues searching with related keywords such as "ChatGPT heading prompt examples."

Opus 4's persona


Impressions after comparative verification

By the way, among the previous comparisons of ChatGPT, Gemini, and Claude, this is the output that left the best impression on me.

Search keyword: "ChatGPT SEO heading creation tips"

## Persona 1:

### 1. Basic information
- Age: 26
- Gender: Male
- Occupation: Web marketing person in charge at a small-to-medium enterprise (3rd year, concurrent position)
- Annual income: 3.8 million yen
- Residential area: Setagaya-ku, Tokyo
- Family structure: Single, living alone
- Economic status: Managing, but wants to invest in himself for skill improvement.

### 2. Situation
- External situation: In charge of website operation and content creation concurrently with sales administration at a specialized trading company with about 50 employees. His boss expects an increase in inquiries via the web, but there are no specific instructions for SEO measures, and he is proceeding almost entirely through self-study. Recently, he has been struggling with the fact that content creation takes too much time, and in particular, he cannot think of attractive headings and PV is sluggish.
- Internal situation: Has many assigned tasks and a strong desire to produce results efficiently. Understands the importance of SEO and feels that headings are the key. Interested in the recently talked-about ChatGPT and tried it a little, but is in a state of trial and error because he doesn't know how to apply it to his work, especially how to use it effectively for SEO. Also has a desire to produce results and be recognized within the company.
- Interaction: Workload and pressure for results (external factors) lead to a strong desire for efficiency and expectations for a new tool (ChatGPT) (internal factors). However, because the specific application method is unknown, it leads to search behavior of wanting to know "tips."

### 3. Goals, requests, and conflicts
- Goal: To be able to effectively utilize ChatGPT to efficiently create headings that are strong in SEO and attract readers' interest. Wants to increase the number of PVs and inquiries on the website and achieve results.
- Requests: Wants to know specific steps when creating headings with ChatGPT and how to write effective prompts (instruction sentences). Wants concrete know-how on how to evaluate and correct generated headings from an SEO perspective. Also wants to understand points to be careful about to avoid failure.
- Conflict: While excited about trying a new tool (ChatGPT), he has anxiety that he might waste time without being able to use it well, or that he might not get the expected SEO effects. He also feels the need to explain ChatGPT utilization to his boss and get their understanding.

### 4. Needs and insights
- Explicit needs: Practical "tips" for heading creation for SEO using ChatGPT. Examples of prompts that can be used immediately. Criteria for judging the quality of generated heading drafts. Specific techniques to increase SEO effects.
- Latent needs: Wants to create a mechanism to reduce the person-dependency of work and produce results efficiently. Wants to improve his skills as a web marketer and gain confidence. Wants to break out of the trial-and-error state and proceed with work with conviction. Desire for approval to be recognized by those around him (especially his boss).
- Insight: Has high expectations for the tool called ChatGPT, but at the same time harbors anxiety such as "Can I really master it?" and "What if I fail?" Therefore, he is seeking concrete, highly reproducible steps, points of caution, and a sense of security that make him think "I can do this too" and "This way, it's hard to fail," rather than just functional introductions or abstract theories.

### 5. Behavior
- Behavior change process:
- Trigger: Confirmed in the end-of-month access report that the PV count of the article he spent time creating did not reach the goal. Speculates that the cause is headings with low click-through rates, especially with little search traffic.
- Changes in emotions/thoughts: Mixed expectations and doubts, thinking "Is the heading weak after all... It takes time to think about it every time, and ideas are running dry. How is it to make headings with ChatGPT? Is it okay for SEO? But efficiency seems to go up..."
- Decision-making point: Recalled that the lecturer said "ChatGPT is effective as a sparring partner for heading creation" at a web marketing seminar he attended the other day, and decided "Let's first look up specific 'tips.'"
- Episode: During work hours, when he had a little free time, he used his desk PC. Opened a new tab in the browser and entered "ChatGPT SEO heading creation tips" into the search window. Thinking, "I want to see an article with lots of specific prompt examples first."
- Search behavior: Tends to click on article titles that include keywords such as "prompt examples," "concrete," and "easy for beginners" from the search results. Also wants to refer to information regarding success stories and introduction effects.

Persona of Gemini 2.5 Pro (Google AI Studio)


From the perspective of "imagining the reader realistically," which is the purpose of setting a persona, the newly released Claude models also feel great, and I think they are on par with Gemini 2.5 Pro (Google AI Studio).

Regarding the prompt instructions, I specified "three personas within 4,000 characters," and Claude's Sonnet 4 followed the instructions perfectly with about 4,100 characters, while Opus 4 used 3,970 characters.

In the case of Gemini 2.5 Pro (Google AI Studio), it sought realism so much that it exceeded 5,000 characters for the three personas...

Looking at the overall capability based on that point, I felt that the output of Claude Opus 4 was the best, but what do you all think?


When creating an article outline

Next, I will verify the output of the article outlines set by each model.


Article outline set by Sonnet 4

When I entered the prompt into Sonnet 4 and executed it, the output was as follows.

Search keyword: "ChatGPT SEO heading creation tips"

Claim:
The key to creating SEO-friendly headings with ChatGPT lies in two things: prompt design and evaluation/revision. Instead of simply asking the AI to "create a heading," it is important to clearly specify the target keyword, intended reader, and the main points of the article. Furthermore, by evaluating the generated heading ideas from an SEO perspective and adjusting them to match the reader's search intent, you can complete attractive headings that are easy to click.

Reason:
Whether ChatGPT can create effective headings depends largely on the quality and quantity of the information provided. Vague instructions will only generate mediocre headings, but by specifically conveying the target keyword, the persona of the intended reader, and the core message you want to convey in the article, the AI can obtain appropriate judgment material. Also, since the heading ideas generated by the AI are not perfect, the process of evaluating and revising them against basic SEO principles (keyword inclusion, alignment with search intent, click-inducing elements) is essential. Through this two-step approach, you can achieve both efficiency and quality.

Specific example:
An effective prompt example is to give specific instructions such as: "You are a professional SEO writer. Using 'side job how to start' as the target keyword, please propose 5 heading ideas for an article explaining how to choose and start a side job for a 30-something office worker who is a beginner at side jobs. The headings should be around 30 characters, include specific numbers, and use expressions that alleviate the reader's anxiety." The generated heading ideas are evaluated based on three points: whether the keyword is naturally included, whether it matches the intended reader's search intent, and whether it has the appeal to make people want to click, and revisions are made as necessary.

Summary:
SEO heading creation using ChatGPT can be significantly streamlined through appropriate prompt design and careful evaluation/revision. Please try practicing these two tips and challenge yourself to create attractive headings that capture the reader's heart.

Sonnet 4's article outline


Article outline set by Opus 4

When I entered the prompt into Opus 4 and executed it, the output was as follows.

Search keyword: "ChatGPT SEO heading creation tips"

Claim:
The key to creating SEO-friendly headings with ChatGPT is to clearly specify the "target keyword," "search intent," and "reader profile." From my experience working with over 100 writers, I have realized that precise instructions to AI determine the results. By mastering three things—effective prompt design, evaluation criteria for generated results, and practical application methods—you can efficiently create attractive headings that aim for top search rankings.

Reason:
For SEO-friendly headings, natural placement of keywords, alignment with search intent, and the appeal to encourage clicks are essential. Since ChatGPT has learned vast patterns of text, it can instantly generate heading ideas that satisfy these elements if given appropriate instructions. However, AI is a tool that depends on the quality of instructions. Vague instructions will not yield the expected results. Therefore, the key to success is to understand basic SEO principles, design specific and systematic prompts, and appropriately evaluate and revise the generated headings.

Specific example:
An effective prompt example is to give specific instructions such as: "You are an SEO writer. Please propose 5 headings for an explanatory article for beginner bloggers with 'ChatGPT SEO utilization' as the main keyword. Please keep them within 32 characters, include numbers, and use a format that shows a question or a solution." The generated results are evaluated based on three points: natural placement of keywords, character count, and appeal to the reader. Furthermore, it is possible to compare and examine multiple ideas and create variations assuming A/B testing.

Summary:
The key to creating SEO-friendly headings with ChatGPT is three things: clear instructions, appropriate evaluation, and continuous improvement. If you practice this method, you can significantly shorten the time for heading creation while also expecting an improvement in search rankings. Please try it starting today.

Opus 4's article outline


Impressions from the comparative verification

By the way, among the previous comparisons of ChatGPT, Gemini, and Claude, this is the output that left the best impression on me.

Search keyword: "ChatGPT SEO heading creation tips"

Claim:
The key to creating SEO-friendly headings using ChatGPT is to "clearly specify search intent," "use specific prompts," and "evaluate and revise AI output." Mastering these three points will enhance your SEO effectiveness.

Reasoning:
Headings are one of the most important elements in SEO, but simply leaving it to ChatGPT is not enough to achieve sufficient results. By clearly incorporating search intent into your prompts, you are more likely to generate headings that capture user interest. Furthermore, preparing specific and concise prompts improves AI accuracy, and evaluating and revising the output from an SEO perspective allows you to consistently create high-quality headings.

Concrete example:
For example, give instructions like: "You are an SEO writer. Please suggest five headings of about 30 characters that include [target keyword] and match [reader's search intent]. Include numbers to increase the click-through rate." After that, it is effective to evaluate and revise the generated headings from the perspectives of "natural keyword placement," "reader-centric appeal," and "differentiation from competitors."

Summary:
SEO heading creation using ChatGPT hinges on prompt design and post-generation evaluation and revision. Put these tips into practice to create headings that resonate with both search engines and users.

GPT 4.5 article outline


In terms of creating an outline, I think both Sonnet 4 and Opus 4 provide quite high quality.

Because it feels logical, persuasive, and practical, I felt that Claude Opus 4 was the best even for the outline.

GPT 4.5 Title Proposals (5 options)


First, regarding heading creation, compared to the previous ones, I feel that Claude Opus 4 is the best.

The logical flow of the headings is smooth, and the connection with the subordinate h3 headings is perfect.

In comparison, Claude Sonnet 4, for example, under the h2 heading '3 Tips for Creating SEO-Strong Headings with ChatGPT', places:

### Reasons Why SEO Headings Are the Key to Article Success
### What Are the Benefits of Using ChatGPT for Heading Creation?
### Common Failure Example: Reasons Why You Shouldn't Leave It Entirely to ChatGPT

It felt like the heading text placed there didn't really fit the 'tips' theme, and the connectivity was subpar.


Regarding the titles as well, including the previous ones, I feel that Claude Opus 4 is the best.

Claude Sonnet 4 is not bad either.

However, there is a slight margin of error in character counting, so in terms of accurate character counting, ChatGPT seems to have the edge.

Opus 4's introduction


Impressions from the comparative verification

By the way, among the previous comparisons of ChatGPT, Gemini, and Claude, this is the output that left the most favorable impression on me.

Hello, I'm Poke-go, who is obsessed with researching prompts to create good articles with generative AI.

If you are thinking about wanting to create SEO-strong headings with ChatGPT, you might be feeling questions or anxieties like these:

"I hear about making headings with ChatGPT, but how do you do it?"
"What exactly should I write for the prompt..."
"Does a heading made by AI really have an effect on SEO?"

You might be feeling such questions or anxieties.

Actually, if you master a few tips, creating effective headings is quite possible even for beginners.

The important thing is not to leave it entirely to the AI, but for humans to firmly carry out the points of "clearly instructing the search intent," "using specific prompts," and "evaluating and revising the AI's output."

If you grasp these tips, you can expect not only to shorten the time for heading creation but also to improve the click-through rate of your articles.

In this article, for beginners who want to challenge themselves with heading creation using ChatGPT, as well as intermediate users who want to deepen their utilization, I explain the following:

- Specific tips and examples for designing effective prompts
- Methods for evaluating and improving generated headings from an SEO perspective
- Applied techniques to further enhance the quality and efficiency of heading creation

I explain the above in an easy-to-understand manner, incorporating my actual experience and verification results as an AI prompt researcher.

It is important not to overthink it and to try it out first.

Please use this article as a reference and try effectively utilizing ChatGPT for your content creation.

Gemini 2.5 Pro (Gemini Advanced)'s introduction


Comparing them, neither Claude Sonnet 4 nor Claude Opus 4 is bad.

However, in terms of whether the flow of the text is natural, I think the introduction written by Gemini 2.5 Pro (Gemini Advanced) is superior.

In terms of which one sounds more like 'me (Pokego),' even looking beyond the introduction, Gemini 2.5 Pro (Gemini Advanced) feels more comfortable.

In terms of generating natural Japanese text, Gemini 2.5 Pro might have the edge.


Summary: The Claude 4 series is excellent, but it might be tough for everyday writing use...

This time, I verified how useful the newly released Sonnet 4 and Opus 4 from Claude are for article creation.


Overall, they have definitely evolved from Claude 3.7 Sonnet and provide high-level output even for writing purposes.

The thinking time for every task was about one minute before moving to output, and I have the impression that it is faster than it was with 3.7 Sonnet.

However, the output speed is slow, and I didn't think Sonnet 4 was particularly fast either. (Of course, Opus 4 is a bit slower.)

But if the difference is only this much, I think it's basically fine to just use Opus 4.


The biggest problem I felt during this verification is that the usage limits are quite strict.


I have a Claude Pro subscription ($20/month), but during this verification, I hit a limit where I was locked out for 2 hours after running only 10 prompts.

Of course, if you upgrade to the higher-tier Max subscription ($100–$200/month), you can use it more, but in that case, I think it would be better to use ChatGPT, Gemini, and Claude together for $20/month each 😅


Claude is quite excellent for things like program development, so I imagine people in that field use the Max plan heavily, but for AI writing purposes, the cost-performance might be poor.

However, it has definitely improved over Claude 3.7 Sonnet, so I would like to use it within the limits of the Pro subscription while considering where it fits best.


So, this time, I used the "High-Quality AI Article Prompt Set" to compare the output of Claude 4's new models for article creation.

I will be comparing outputs for other processes in the future as well, so please look forward to it!
