GPT-5-Codex now extends this unified setup with deeper engineering capabilities — even running "independently for more than 7 hours at a time on large, complex tasks" according to the company.

From cloud hand-offs to GitHub reviews, GPT-5-Codex is optimized for agentic coding and designed to supercharge developer workflows.

Data annotation—labeling text, images, and video for training—is central to A.I. Grok maker xAI is shifting from generalists to domain experts.

The new model is specifically designed to handle complex software engineering projects and can help with vibe coding, too.
