Key insights

Concrete technical or product signals.

  • Strong fit when your org already procures OpenAI/ChatGPT Enterprise and wants a first-party coding agent with centralized policy.
  • Measure on your real repos—gains depend on test coverage, modular boundaries, and review culture.

Use cases

Where this shines in production.

  • Greenfield services with solid automated tests
  • Migration tasks with repetitive but well-scoped edits
  • Internal developer portals that already authenticate via OpenAI-managed identity

Limitations & trade-offs

What to watch for.

  • Feature parity and rollout cadence differ from consumer ChatGPT—track release notes for your SKU.
  • Agents can still propose insecure patterns—enforce static analysis and secret scanning in CI.
