Claude Code integrates Codex via two distinct architectures: one-shot or persistent

Two distinct architectural approaches for integrating AI models like Codex with Claude Code are detailed. The first, 'codex exec,' is a one-shot subprocess model suitable for tasks requiring a single, verifiable output with minimal state management. The second, 'Codex App Server,' employs a persistent runtime for more complex, stateful collaborations that may need to resume or be interrupted. The article also highlights the importance of accurate version tracking for these tools, noting discrepancies between marketplace sources, cached snapshots, and active plugin versions. AI

IMPACT Provides developers with architectural choices for integrating AI models, impacting workflow efficiency and task suitability.
