Agents API is a bigger deal than it seems.

OpenAI's bet on making the Codex harness open-source could pay off big time here.

This harness-as-a-service idea hasn't hit mainstream yet, but some of the most serious builders are already adopting it to unlock new types of services.

Codex being open-source means that many other models (open or closed) are already extremely knowledgeable about the Codex harness. As more services adopt these new agentic architectures, you'll want the compounding effect that comes with that transparency and openness.
