OpenAI launched GPT-5.3 Codex, achieving a record 77.3% on Terminal-Bench 2.0. Following Anthropic's Claude Opus 4.6, the model prioritizes efficiency with 2.09x fewer tokens and 25% faster speeds. By optimizing for GB200-NVL72 architecture, OpenAI enables real-time steering of tasks without losing context. This pivot from raw scaling to hardware-software co-design marks a critical evolution toward sustainable, agentic AI systems. 🚀💻
