Its greatest strength lies in its ability to process various forms of data, including text, images, audio, and video, in an integrated manner. It is expected to demonstrate even more advanced performance, leveraging Google’s extensive data and technology.

Tier Classification: Evaluating Based on Real-World Usage Examples

So, which tier do these three AI tools belong to? It can't be determined solely based on benchmark scores. We will compare and analyze the strengths and weaknesses of each tool based on real-world usage examples to rate their tiers.

S Tier: Overwhelming Performance and Productivity Enhancement – ChatGPT (GPT-5.2)

ChatGPT remains the most powerful tool for overall productivity enhancement. Its coding capabilities have further improved with GPT-5.2, providing significant assistance to developers in various tasks, such as implementing complex algorithms, debugging, and optimizing code. Writing capabilities have also been significantly improved, enabling efficient handling of various writing tasks, such as marketing content creation, report writing, and email composition. While it has a few drawbacks compared to Claude or Gemini, it’s still considered the most widely usable AI tool.

A Tier: Demonstrating Outstanding Strengths in Specific Areas – Claude (Sonnet 4.6)

Claude outperforms ChatGPT in creative writing tasks and those requiring understanding of long contexts. It demonstrates outstanding capabilities both in professional fields such as summarizing complex legal documents and analyzing academic papers. enhanced personal data protection makes it safer to use in enterprise environments. However, its coding capabilities are lacking compared to ChatGPT, which is a bit of a drawback.

B Tier: High Potential, But Still Requires Improvement – Gemini (3 Pro)

Gemini emphasizes its strengths in multimodal functionality and fast processing speed, but its overall performance is still lacking compared to ChatGPT or Claude. Improvements are needed in areas such as text generation consistency, understanding of complex prompts, and accuracy in responding to ethical issues. However, it is expected to grow rapidly with Google's continued investment and technological development.

C Tier: Potential for Learning and Improvement – (Unclassified)

Numerous AI tools besides ChatGPT, Claude, and Gemini currently exist in the market. These tools have their own strengths, but they are still lacking compared to tools belonging to the S, A, and B tiers. However, with the advancement of open-source AI models, these tools are also expected to grow and improve rapidly.

Recommendations by Use Case: Choosing the Right AI Tool for You

• Developers: Functionality needed for overall development tasks, such as coding, debugging, and code optimization, is the most important. Therefore, ChatGPT (GPT-5.2) is recommended.
• Writers: Professional writing skills, such as creative writing, understanding of long contexts, and generating responses to ethically sensitive topics, are important. Therefore, Claude (Sonnet 4.6) is recommended.
• General Users: An AI tool that can efficiently handle various tasks such as text generation, translation, and summarization is needed. Therefore, ChatGPT (GPT-5.2) or Gemini (3 Pro) are recommended (Gemini is a better choice if you're interested in utilizing multimodal functionality).

Future Outlook: AI Competition Will Intensify Further

Currently, in 2026, ChatGPT remains the leader in the AI productivity tool market, but competition is expected to intensify further due to the rapid growth of Claude and Gemini. The advancement of open-source AI models will also act as a variable that can shake up the market space. It is important to remain interested in the ever-changing AI ecosystem and choose an AI tool that suits you to improve productivity.

are an evaluation based on the current point in time. The tiers can change at any time due to the emergence of new models and updates to existing models, so please keep that in mind. We hope you choose and utilize an AI tool that suits you to create a more efficient work environment.
