OpenAI's Codex Dominates Internal Workflows

OpenAI's internal Codex tool has rapidly become the backbone of operations, with non-engineering teams like finance, recruitment, and legal moving nearly all workflows onto it. Usage surged from near 0% to 90% within four months, driven by the tool's ability to handle complex, long-running tasks. The company now operates as an 'agentic software factory,' with Codex agents automatically monitoring and fixing production issues.
