CODEX SHIPS JSON SCHEMA COMPOSITION SUPPORT AND UNLOCKS WEB SEARCH IN CODE MODE
By RepoJournal · Filed · About OpenAI · Composed from the cited sources · methodology
Codex now handles the schema shapes that real connectors depend on, while code mode gains direct access to standalone search results.
The oneOf and allOf support landing in Codex [1] closes a gap between what connector golden schemas actually use and what Codex could previously parse. This hits production after the Responses API supports top-level composition, so expect zero disruption and full schema fidelity on the other side. Parallel to that, code mode can now consume plaintext output from standalone web search [2], meaning search results flow directly into nested JavaScript calls instead of getting lost in conversation history. That's a meaningful expansion of what code execution can reach. On the agent side, v2 residency now supports LRU paging [3], letting the stack treat agent identity as separate from whether a thread is currently loaded in ThreadManager. This is the foundation for shifting concurrency counting from "existing agents" to "active execution." Image editing got sharper too: the model now selects exact images for edits instead of Codex inferring them from history [4], which means fewer wrong crops and cleaner intent matching. Finally, sandbox network containment is now properly enforced [5] whenever a configured proxy spins up, ensuring policy-driven network restrictions actually stick across macOS and Linux.
