OpenAI’s Codex and Anthropic’s Claude spark coding revolution as developers say they’ve abandoned traditional programming

Is traditional coding dead? That’s the question many developers have been asking themselves this week following the launch of powerful new coding models from OpenAI and Anthropic.

Last week, OpenAI and Anthropic dropped their respective coding models—GPT-5.3-Codex and Claude Opus 4.6—both of which represented significant leaps in AI coding capabilities. GPT-5.3-Codex showed markedly higher performance on coding benchmarks than earlier models, while Opus 4.6 introduced a feature that lets users deploy autonomous AI agent teams that can tackle different aspects of complex projects simultaneously. Both models can write, test, and debug code with minimal human intervention—even iterating on their own work and refining features before presenting results to developers.

The releases—especially GPT-5.3-Codex—sparked something of an online existential crisis among software engineers. At the heart of it was a viral essay written by Matt Shumer, CEO of OthersideAI. Shumer said that “something clicked” following the model releases and described AI models now handling the entire development cycle autonomously—writing tens of thousands of lines of code, opening applications, testing features, and iterating until satisfied, with developers simply describing desired outcomes and walking away. He proposed that the advances meant that AI could disrupt jobs more........
