This release is positioned as a major step forward for agentic and iterative coding workflows, with improvements in planning, execution, and refinement across complex tasks. We begin with a technical overview and first impressions, then move into extensive real-world testing. These tests include browser-based OS workflows, 3D printer simulations with STL generation, flight combat simulators, C++ game development, Python FPS agentic tasks, and multimodal website generation. We also run multiple improvement rounds to see how well GPT-5.3 Codex iterates on its own results.
