1. Endava Details Building an Agentic Organization on Codex

OpenAI. OpenAI published a case study with IT services firm Endava describing how it is restructuring delivery teams around Codex rather than treating the tool as a per-developer assistant. The framing is organizational rather than individual: Endava plumbs Codex into its standard project workflows so agentic coding becomes the default execution layer across client engagements. The post extends OpenAI’s run of enterprise Codex stories that emphasize integration into existing review and delivery pipelines over raw productivity claims. Source

2. OpenAI Publishes Its Frontier Governance Framework

OpenAI. OpenAI released its Frontier Governance Framework, formalizing how the company evaluates and decides to deploy increasingly capable frontier models. It matters because it codifies internal review gates and risk thresholds into a stated policy rather than ad hoc judgment, giving partners and regulators a reference for how deployment decisions are made. The publication lands alongside OpenAI’s broader 2026 push on safety and elections messaging. Source

3. Codex CLI 0.135.0 Adds Richer Diagnostics, Permission Profiles, and Vim Text Objects

OpenAI. OpenAI shipped Codex CLI 0.135.0, expanding the codex doctor command into a fuller support-diagnostics tool that inventories environment, Git, terminal, app-server, and thread state for troubleshooting. The /status view now surfaces remote connection details and server version when the TUI runs over a remote transport, and /permissions understands named permission profiles and displays configured custom profiles. Editor work includes Vim text-object editing with improved word and line-end behavior and a configurable interrupt-turn binding, while packaged builds can discover and use the bundled patched zsh helper across macOS and Linux. The Python SDK gains friendly Sandbox presets for the thread and turn APIs, and fixes improve Markdown table rendering, TUI stability on macOS and Zellij, slash-command completion, and tmux/iTerm control-mode keyboard handling.
