AI Smarter Than Human Developers? The World of ‘Self-Working AI’ Created by Anthropic

Imagine you are taking a grueling software developer hiring test. You have to write complex code and solve performance issues within two hours. In this test, the candidate sitting next to you scores higher than any other human applicant. But what if that candidate isn’t a person, but an artificial intelligence (AI)?

This movie-like scenario has actually happened in reality. On November 24, 2025, AI research company Anthropic unveiled its latest model, ‘Claude Opus 4.5,’ and revealed a stunning fact: this AI model scored higher than any human candidate in a difficult technical test designed for hiring actual engineers Anthropic unveils Claude Opus 4.5, its latest AI model - CNBC.

Today, we take a look inside the engineering world of Anthropic, the company behind this incredible AI. How are they working with AI, and why are genius developers from all over the world flocking here? Let’s explore the future they dream of, beyond just the secret of writing good code.

Why is this important?

Beyond the mere fact that AI is good at coding, this signals a fundamental change in how we work. In the past, developers stayed up all night typing code line by line; now, AI creates the draft, and humans shift into roles that judge whether the direction is correct and, crucially, ‘safe.’

Anthropic focuses on building AI that is not just ‘smart,’ but ‘reliable, interpretable, and steerable’ Home \ Anthropic.

To use an analogy, they aren’t just building a runaway train that’s only fast; they are building a high-performance electric vehicle with reliable brakes that precisely follows the driver’s instructions. This means designing ‘safety mechanisms’ from the depths of the system to ensure that the financial or medical services we use don’t suddenly act erratically or provide dangerous information. For Anthropic, engineering is not just about creating features, but a mission to provide safe tools for humanity Engineering\Anthropic.

Easy to Understand: The ‘AI Coworkers’ of Anthropic Engineers

Developers at Anthropic never work alone. They collaborate as a team with Claude, the powerful AI they created. Let’s compare their unique way of collaboration to scenes we often see in daily life.

1. The 24/7 ‘Senior Code Reviewer’

Developers go through a ‘Pull Request’ process, where the code they’ve written is reviewed by others before being integrated into the existing system. At this stage, Anthropic engineers use a dedicated Claude Plugin like a teammate Engineering – Claude Plugin | Anthropic.

2. The ‘Genius Assistant’ That Never Forgets (Context Engineering)

When talking to AI, it can be frustrating when it seems to forget previous details. To solve this, Anthropic puts immense effort into ‘Context Engineering’—the technology that optimizes how much information an AI can remember and process at once Anthropic.

Simply put, this is like summarizing a massive encyclopedia into its core essence on a single Post-it note (Compaction), or writing down necessary details in a separate notebook to accurately retrieve them later (Memory tool). Thanks to this, Claude can perfectly remember and assist with the entire flow of complex software projects that span days or weeks Anthropic.

3. The ‘AI Special Forces’ That Exercise Teamwork Automatically

Anthropic uses ‘Multi-agent harness’ technology, which operates multiple AI agents (AI systems that judge and act independently to achieve specific goals) simultaneously Anthropic | LinkedIn.

Current Status: How AI Has Transformed the Workplace

Anthropic actually investigated how their own work style has changed because of AI. In August 2025, they surveyed 132 engineers and researchers and conducted 53 in-depth interviews, confirming that tools like ‘Claude Code’ have completely transformed their daily lives How AI Is Transforming Work at Anthropic \ Anthropic. Now, developers are moving away from simple repetitive tasks to focus on more creative design.

Thanks to this innovative technology and work culture, Anthropic has become the ‘dream job’ that developers worldwide most want to join. According to a 2025 report, top talent from prominent companies like OpenAI and Google DeepMind is moving to Anthropic OpenAI and DeepMind losing engineers to Anthropic in one …. Anthropic is currently growing so rapidly that it is looking for new talent in over 426 roles across the globe, including San Francisco and London JobsatAnthropic.

However, they don’t just build features. Anthropic is home to experts in Prompt Engineering—the design of instructions to elicit optimal responses from AI—such as Amanda Askell. Together, they perform the ‘philosophical work’ of refining AI to ensure it doesn’t just become smart, but behaves in alignment with human ethics and values AI prompt engineering: A deep dive - YouTube.

What’s Next?

The emergence of Claude Opus 4.5 is a significant event signaling the dawn of the ‘Autonomous Engineering’ era The New Sovereign of Silicon: Anthropic’s Claude Opus 4.5 …. AI is evolving beyond a level where it just writes code as instructed, becoming an ‘autonomous partner’ that can diagnose problems and design software on its own even while human engineers are asleep.

Of course, Anthropic does not forget the importance of infrastructure, which serves as the fundamental strength in this process:

• Service Mesh: A traffic control system that helps numerous AI services communicate smoothly without getting tangled.
• Observability: The ability to observe and understand the internal state of the system in real-time to identify any issues.

In the future, we will live in a world composed of code directly designed and verified by AI. How safe and convenient that world will be depends on how deeply and correctly Anthropic’s ‘reliable and steerable AI’ technology takes root in human life.

AI’s Take

Engineering at Anthropic is not a process of AI taking human jobs, but a beautiful process of collaboration that helps humans focus on higher-level problem-solving and the essential value of ‘safety.’ The achievements shown by Claude Opus 4.5 are just the beginning; soon, AI will establish itself by our side as our most dependable, smart, and, above all, ‘trustworthy’ colleague. What kind of AI colleague would you like to work with?
