OpenAI made waves this week by adding Codex – a multitasking AI coding agent – directly into ChatGPT. Unlike basic chatbots, Codex acts like a digital coworker that can juggle several programming jobs simultaneously. Developers using ChatGPT Plus can find Codex in the sidebar, where they can assign tasks like ‘build login page’ or ‘fix database error’ through simple prompts. The tool shows progress updates and lets users ask follow-up questions about their codebase, making teamwork with AI more transparent.

Google countered with AlphaEvolve, its new self-improving AI for technical tasks. This system doesn’t just write code – it evolves better versions of itself to tackle complex math problems and chip designs. In tests, AlphaEvolve solved over 50 open math challenges as well as human experts, while cutting weeks off software timelines. Engineers describe it as an ‘autonomous hacker’ that finds creative solutions humans might miss.

For the Java community, 2025 brings game-changing tools that blend classic coding with AI smarts. The MCP Java SDK and Spring AI let developers build fraud detection systems and language-aware apps without learning Python. These libraries handle heavy lifting like connecting to AI models and managing data flows, allowing Java teams to focus on business logic. Real-world examples include apps that automatically tag support tickets and prevent payment scams using these tools.

The business side of AI coding keeps exploding. Cursor, a startup making AI pair-programming tools, hit $300 million in annual sales and seeks funding at a $9 billion valuation. OpenAI’s rumored $3 billion acquisition of Windsurf aims to combine Codex with Windsurf’s SWE-1 models – which already rival top systems like Claude 3.7 Sonnet. Meanwhile, Anthropic and Microsoft keep improving their coding assistants, creating a crowded but innovative market.

Not all news was positive – Meta delayed its Behemoth AI model due to performance issues, causing internal frustration. However, smaller companies thrive: ElevenLabs owns 80% of AI audio generation, while Kling dominates 30% of video AI. As coding tools get smarter, developers worldwide gain powerful allies – but the competition between tech titans grows fiercer every week.
