Anthropic, a major artificial intelligence company, has just released Claude Sonnet 4.5, an AI assistant that can work independently for up to 30 hours on complex tasks. This is a big jump from its previous version, which could only work alone for seven hours. The company claims this is now “the best coding model in the world,” and it’s designed specifically for professional work in areas like cybersecurity, finance, and research.
Claude Sonnet 4.5 coding capabilities represent a major step forward in what AI can do without human help. But what does this mean for people who work with technology every day?
An AI That Thinks Like a Professional
Unlike simple chatbots that answer questions, Claude Sonnet 4.5 is built to handle long, complicated projects that usually require skilled professionals. It can plan and execute software projects that span hours or days, write secure code, and even coordinate with other AI tools to solve complex problems.
According to Jared Kaplan, Anthropic’s chief science officer, “People are just noticing this model because it’s smarter and capable of working on problems and fixing them”. The AI scored at the top of industry tests for software coding skills, outperforming other AI models on benchmarks like SWE-bench Verified.
What makes this particularly impressive is that the AI can maintain focus on complex, multi-step tasks for the entire 30-hour period, providing regular updates on its progress.

Real-World Applications That Could Change Industries
The potential uses for this technology go far beyond simple coding assistance. According to Google Cloud’s announcement, Claude Sonnet 4.5 can handle several professional tasks:
- Cybersecurity:Â Deploy systems that automatically patch security vulnerabilities before hackers can exploit them, shifting from reactive to proactive defense.
- Financial Analysis:Â Monitor global regulatory changes and automatically adapt compliance systems for banks and financial institutions.
- Software Development:Â Complete entire coding projects that would normally take teams days or weeks to finish.
The AI is also designed to be safer and more reliable than previous versions. Anthropic has reduced concerning behaviors like deception and power-seeking, making it more suitable for high-stakes professional environments.
What This Means for Workers and Job Markets
For people in emerging economies, this development presents both opportunities and challenges. On one hand, small businesses and startups could access professional-level AI assistance without hiring expensive specialists. A local business could use Claude Sonnet 4.5 to build secure websites, analyze financial data, or strengthen its cybersecurity.
On the other hand, this technology raises important questions about the future of certain tech jobs. If an AI can work independently for 30 hours on complex coding tasks, what does this mean for entry-level programmers and analysts?
However, experts suggest that rather than replacing workers entirely, tools like Claude Sonnet 4.5 are more likely to change how people work, allowing them to focus on higher-level strategy and creativity while the AI handles routine technical tasks.
The key will be adapting to work alongside these powerful tools rather than competing against them.
