OpenAI Reaccelerates Codex Development

This highlights OpenAI's renewed focus on its coding roadmap:
- They launched GPT-5 in the summer of 2025, positioning it as a "pair programmer," but initially fell behind more agentic workflows like Claude Code in the new wave of agentic coding competition.
- A small internal team at OpenAI then spun off to focus exclusively on an independent Codex model line and product, untethered from serving ChatGPT's massive user base.
- By November/December 2025, with the rollout of version 5.3, this product line is considered to have become truly competitive, with its pace of progress visibly accelerating.
