OpenAI Releases GPT‑5.3‑Codex — 25% Faster Agentic Coding Model That Can Build Complex Games & Apps From Scratch Over Days
OpenAI has officially launched GPT‑5.3‑Codex on February 5, 2026, describing it as its most capable agentic coding model to date and 25% faster than the prior generation. The model combines the frontier coding performance of GPT‑5.2‑Codex with GPT‑5.2’s reasoning and professional knowledge, enabling longer-running workflows that involve research, tool use, and complex execution. OpenAI says GPT‑5.3‑Codex can iteratively build highly functional complex games and apps from scratch over the course of days, running autonomously over millions of tokens while users steer and interact without losing context.

OpenAI Retires “Codex for macOS” (Standalone) as Focus Shifts to Agentic Coding — Codex Becomes a Multi‑Agent Command Center Across CLI, IDE, and Cloud
OpenAI did not "cut off the macOS version of Codex" - on the contrary, it released its official Codex app for macOS on February 2, 2026, positioning Codex as a "command center for agents" that focuses on parallel agents, long task collaboration, and secure execution. If your news topic is "Cutting off macOS version of Codex, fully intelligent", a more accurate way to write it is: OpenAI is cutting down/weakening the "traditional monolithic Codex form" (such as single tool/single interface/single workflow), pushing Codex into a cross CLI/IDE/cloud/mobile agentic platform, and iteratively strengthening the capabilities of "long-range tasks, refactoring migration, and collaboration" with models such as GPT-5/5.2-Code.
