This weekly update covers major developments in artificial intelligence and coding tools that happened recently. The big story is what experts are calling the AI Coding Wars—a competition between major tech companies to build the best AI tools for programmers.

Google made a huge splash by releasing Antigravity, a new tool for writing code that came out on November 18. Unlike older AI coding helpers, Antigravity is different because it uses AI Agents—smart computer programs that can work on their own without a person telling them every single step. Think of agents like helpful robots that can write code, test it, open a web browser to check if it works, and even take screenshots to show you what they did. Multiple agents can work on different jobs at the same time, so instead of waiting for one agent to finish before starting another, they all work together like a team.

The exciting part about Antigravity is that it's free to use right now, and it comes built into a popular programming tool called VS Code. Google powered it with their newest AI model called Gemini 3 Pro.

But Google wasn't alone in making big announcements. Just a few days later, another company called Anthropic released their own powerful AI model called Claude Opus 4.5, which they say is the best for writing code. Then OpenAI, the company behind ChatGPT, announced GPT-5.1 and special coding versions called Codex that can work by themselves for a whole day without human help.

In other exciting news, Microsoft and NVIDIA announced they would give $15 billion to Anthropic to help bring Claude into Microsoft's business software. This shows how serious companies are about AI for work.

However, there's something scary too. Experts discovered what looks like the first cyberattack completely run by AI agents. In this attack, AI systems did everything—they looked for weak spots, moved around inside computer systems, and caused damage—all without a human hacker giving commands. This means companies need to be more careful about how they use AI agents.

Also, researchers looked at what developers actually think about AI agents. About half of developers (52%) either don't use agents yet or like simpler AI tools better. But among developers who do use agents, the results are really good—70% say agents make their work faster.

AWS, which is Amazon's cloud computing business, also announced new categories for partners who work with agentic AI, showing that this technology is becoming more mainstream and important for businesses.
