OpenAI expands Codex's default context from 272K to 500K—up to 1M, with no long-context surcharge on subscription usage. It effectively rolls back a number it had quietly cut itself weeks earlier, though concerns about quota consumption and retrieval accuracy remain.
OpenAIがCodexの既定コンテキストを272K→500Kへ拡張し、最大1M、サブスク利用分は長文追加料金なしに。数週間前に自ら削った数字を巻き戻した格好だが、クォータ消費や検索精度への懸念も。
Codex CLI 0.162 adds a tool that lets the agent itself create "managed git worktrees." It makes parallel tasks pinnable in the command center, pulling the groundwork for unattended, parallel operation inside the agent. The challenge of where to draw trust boundaries remains.

OpenAI's Codex lead pledged that for 28 days the team will either ship one improvement that helps most users every day or reset everyone's usage limits. Day one boosted generation speed by about 1.5x. We lay out the aims—and the criticism that it turns usage into a gamble.
OpenAIのCodex責任者が『28日間、毎日ユーザーに効く改善を1つ出すか、全員の利用上限をリセットするか』を公約。初日は生成速度を約1.5倍に。狙いと、ギャンブル化との批判までを整理します。

At DevDay 2026, Codex is reworked into an always-on development platform that spans devices. It adds voice control and parallel work via /agents, automated code review, and Codex Security Cloud, while GPT-6.1 Sol cuts unit price to about a fifth and Ultrafast reaches around 300 tokens per second.
DevDay 2026でCodexが端末をまたぐ常駐開発基盤に刷新。音声と/agentsの並列作業、自動コードレビュー、Codex Security Cloudを追加し、GPT-6.1 Solが単価を約5分の1、Ultrafastが毎秒約300トークンへ。
OpenAI's Codex made git worktree sessions the default in 0.156, released September 23. Disposable conversations become durable workshops you can isolate, resume, and review, leaning the tool toward a parallelism-first workflow. A /usage dashboard and a full-screen TUI were tidied up at the same time
