Sateezg/codex-bridge was created 2026-08-09 and took 359 stars in about two days. It's a Shell-based Claude Code plugin that gives Claude access to GPT-5 subagents and gpt-image-2 image generation by routing through an existing Codex CLI OAuth session rather than an OpenAI API key. This is the same subscription-arbitrage pattern that showed up in openclaude's loopback proxy hosts last week, now pointed the other direction — cross-vendor rather than provider-swapping — and it means a developer paying for two coding-agent subscriptions can use both models from one harness without a third billing relationship.
