What happened
While everyone watched model releases, something else happened. Anthropic released Agent Skills as an open standard. OpenAI adopted it.
The same skill format now works across Claude, Codex and ChatGPT. Skills encode institutional knowledge. Your compliance workflows. Your architecture patterns. Your way of doing things.
Once encoded, that knowledge compounds. Every process you teach the model becomes available to every person in your organization, instantly.
Warning
If you're still thinking about AI as "which model should we use," you're already asking the wrong question.
What this means
The companies building skills libraries today aren't just getting more efficient. They're creating organizational capability that takes years to develop.
The ones waiting will find themselves trying to close that gap in months.
Compounding
Skills encode institutional knowledge. Once encoded, that knowledge compounds across every person in your organization, instantly.
