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.
