This week, the world of computer programming saw huge changes with AI helpers that can write code all by themselves. The biggest news is that OpenAI Codex, a powerful AI tool made by OpenAI, is now ready for everyone to use. Codex can read your code, understand what it does, and then write new code to help you. It even runs tests and opens pull requests, which are ways programmers share their work with teammates.

Another big announcement came from Cursor, a company that makes code editors. They released a brand new AI model called Composer that writes code four times faster than other AI helpers. Composer is so smart that it can work with other AI agents at the same time to solve really hard problems.

The company GitHub held a big event called GitHub Universe 2025 to talk about how AI agents are changing the way people write code. These AI agents can do boring jobs so programmers can focus on the fun and important parts. GitHub announced something called Agent HQ, which lets programmers control multiple AI agents from one place.

Microsoft also released new tools for building AI agents in October. They made something called Copilot Studio 2025 Wave 2 that helps people create AI agents without writing code. Anthropic, another company, released an AI called Claude Sonnet 4.5 that can write code safely and explain what it's doing.

Google made a tool called AI Studio that lets anyone build AI programs without being a programmer. This is called "vibe coding" because you just tell the computer what you want in regular words.

At a big tech event called NVIDIA GTC in Washington, D.C., companies talked about how AI agents are making computer programming faster and better.

All of these new tools show that AI is becoming a real teammate for programmers. Instead of just helping you type faster, these AI agents can plan their own work, write code, test it, and even review what other AI agents wrote. This is called agentic development, and it's changing everything about how software gets built.
