If you’re wondering why Anthropic’s new ‘Claude Code’ isn’t just another development tool added to the list but a ‘game changer’ that will completely reshape how we work, be sure to read this article to the end.
I will perfectly analyze everything from the emergence of an ‘agent’ that directly controls your computer rather than just a simple coding assistant, to the amazing performance differences and cost efficiency that occur when you forcibly apply the high-performance ‘Opus’ model that others don’t know much about.
If you are an investor or practitioner chasing global economic outlooks and AI trends, you must not miss the context of this change right now.

[Deep Dive] Anthropic ‘Claude Code’: The Future of Coding, Testing Limits with the Opus Model

1. [News Briefing] AI Taking Over the Terminal, The Arrival of ‘Claude Code’

While existing AI coding tools only offered “advice” next to web browsers or code editors, Claude Code, released by Anthropic this time, shows a completely different approach.
Simply put, it’s as if AI has entered the ‘Terminal’, the developer’s home ground, and taken over the keyboard.

Terminal, not Web: Without needing to open a browser, perform tasks by conversing directly with AI in the black terminal window.
Agentic Workflow: Beyond simply writing code, it reads file systems, edits them, and directly executes terminal commands. In other words, it “performs” rather than “suggests”.
Intuitive Installation: If you have a Node.js environment, immediate adoption is possible with a single npm install command line.

This is not just an evolution of a utility, but can be seen as the latest AI Trend case showing how ‘automation of labor’, the core point of the 4th Industrial Revolution, is implemented in the realm of knowledge workers.

2. [Insight] The Key Takeaway Others Won’t Tell You: Sonnet vs Opus, Which Should You Choose?

Most news only covers that “Claude Code has been released,” but the really important thing is that the results vary vastly depending on ‘which brain’ you swap in.
The default setting is ‘Sonnet 3.7’, which is good for cost-performance and speed, but you must pay attention to the fact that true senior developer performance comes out when you change the setting to the ‘Opus’ model based on original analysis results.

Speed vs Intelligence Trade-off: Speed is life in the terminal environment. So the default, Sonnet, is snappy. However, Opus is overwhelming when designing complex architectures or untangling legacy code that is twisted beyond belief.
Economics of Cost: Opus is definitely expensive and slow. But what if it solves a problem in 5 minutes that a developer would dig at for 3 hours? This is exactly where the ‘productivity revolution’ that companies pay attention to in the global economic outlook occurs.
Conclusion: The smartest way to use it is to use Sonnet normally, and ‘mode change’ to Opus only when faced with an unsolvable difficulty.

3. From Installation to Action: 5-Minute Cut Guide

Without complex explanations, I’ll summarize how to plant this AI agent in your computer right now.
This process is very intuitive, so it will help even non-developers understand the flow.

1) Installation
Open the terminal and enter the command below.
npm install -g @anthropic-ai/claude-code
With this one line, global installation is complete.

2) Execution and Authentication (Auth)
Type claude to wake up the agent.
When you run it for the first time, an authentication process pops up; just link it with your Anthropic account via a web browser and you’re done. Now the terminal becomes a chat window.

3) Changing Models (The Secret Sauce)
This is the core point mentioned above. Use the command below when you need a smarter brain.
/config set model [model name] (e.g., claude-3-opus-20240229)
Doing this makes the AI understand and infer the entire context of the project more deeply.

4. Differentiated Performance Shown by Claude Code

If you use or analyze it yourself, it definitely has a different texture from existing ‘Copilot’-style services.
The core point is not just autocompleting code, but understanding ‘Context’ and using ‘Tools’.

Context Retention:
If you say, “You know that file we fixed earlier, fix this part there too,” it understands.
It remembers the flow of conversation and edit history while the terminal session is maintained.
Automated Tool Usage:
I don’t need to open files one by one and copy the contents.
The AI autonomously executes ls (view file list), grep (search content), and cat (read file) commands to collect necessary information.
Safety First:
Isn’t it dangerous if AI executes terminal commands recklessly? It is designed to strictly receive user approval (Yes/No) before executing commands that delete files or touch the system.
These details are the points companies look at most importantly when adopting AI.

5. Conclusion: Paradigm Shift in Development Environment

Claude Code is not just a simple coding tool update.
It is the signal flare that breaks down the boundaries between the IDE (Integrated Development Environment) and the terminal, elevating AI from a ‘chat partner’ to a capable ‘colleague’ sitting right next to you.

Even if Sonnet 3.7 is mainstream right now due to cost issues, as we confirmed through the Opus model, as AI’s reasoning ability increases, human developers will focus more on ‘design’ and ‘decision making’ rather than ‘coding’ itself.
This will lead to an overall improvement in productivity in the IT industry, and will have a significant impact on employment forms and economic structures in the technology sector in the long term.

If you are a developer, open the terminal right now. Because a powerful weapon that will expand your thinking process is right there.

< Summary >

Claude Code Launch: Anthropic released an agent-type AI coding tool that runs directly in the terminal, not on the web.
Agentic Workflow: Beyond simple code suggestions, it ‘performs’ tasks like a real developer, such as accessing file systems and executing commands.
Importance of Model Selection: The default model (Sonnet) is fast, but changing settings to use the high-performance model (Opus) maximizes complex reasoning and problem-solving abilities.
Installation and Use: It can be easily installed with the npm command, and if you command in natural language, the AI judges and uses necessary tools on its own.
Implications: As a case showing that AI has entered the stage of a practical ‘colleague’ beyond simple assistance, the paradigm of work productivity is changing.
