Codex Sites Is Not No-Code. It Is Deployment Power With an Approval Problem.

Codex Sites Is Not No-Code. It Is Deployment Power With an Approval Problem.

Codex Sites will be tempting to describe as “no-code.” Don’t. That undersells both the feature and the risk. OpenAI’s Sites documentation says Codex can create, save, deploy, and inspect websites, web apps, dashboards, internal tools, and games hosted by OpenAI. It can turn a prompt or compatible existing

GPT-5.5 Is Now the Codex Default Recommendation. The Real Question Is When Not to Use It.

GPT-5.5 Is Now the Codex Default Recommendation. The Real Question Is When Not to Use It.

OpenAI’s Codex model guidance now has a simple recommendation: for most tasks, start with gpt-5.5. That is good advice for an individual staring at a hard problem. It is incomplete advice for a team paying for a fleet of agents. The refreshed Codex models page positions gpt-5.5

OpenAI’s Codex Credits Page Is the Budget Policy Engineering Teams Actually Need

OpenAI’s Codex Credits Page Is the Budget Policy Engineering Teams Actually Need

The most important Codex feature this week is not a new editor trick, a bigger context window, or another agent surface. It is a billing control. That sounds like accountant bait until you remember what coding agents have become: long-running, tool-using, sometimes-parallel workers that can burn real money while producing

Copilot’s GPT-5.2 Cutover Is a Model-Routing Drill, Not Just a Dropdown Cleanup

Copilot’s GPT-5.2 Cutover Is a Model-Routing Drill, Not Just a Dropdown Cleanup

Model deprecations used to be a mild annoyance: a dropdown changed, autocomplete felt different for a week, and everyone moved on. In 2026, that is not how coding agents work. When GitHub removes GPT-5.2 and GPT-5.2-Codex from most Copilot surfaces, it is not cleaning up a menu. It

Fix with Copilot Turns Failed GitHub Actions Into Agent Work. Useful, If You Keep the Blast Radius Small.

Fix with Copilot Turns Failed GitHub Actions Into Agent Work. Useful, If You Keep the Blast Radius Small.

“Fix with Copilot” for failing GitHub Actions is a genuinely good agent use case, which is precisely why it deserves more scrutiny than the average AI button. CI failures are narrow, evidence-rich, and measurable. They are also where teams often confuse “green” with “correct.” GitHub has put an agent directly

GitHub Just Made Copilot Plugins an Enterprise Policy Surface in VS Code

GitHub Just Made Copilot Plugins an Enterprise Policy Surface in VS Code

GitHub’s enterprise-managed plugins preview for VS Code is the sort of changelog item that reads like admin plumbing until you picture the incident review. “Who installed the agent plugin that could see the deployment logs?” “Which MCP server did Copilot call?” “Why did every developer suddenly have a hook

Codex 0.138 Alpha Is Where Remote Control, Token Usage, and Permission Policy Stop Being Plumbing

Codex 0.138 Alpha Is Where Remote Control, Token Usage, and Permission Policy Stop Being Plumbing

Codex 0.138.0-alpha.6 looks like a small alpha tag if you only read the release page. That would be the wrong review. The interesting work is not in a glossy changelog; it is in the plumbing OpenAI is turning into policy: remote-control status, app-server account sessions, token usage,

Codex App 26.602 Is a Small UX Release With a Big Tell: Agents Need Observability for Humans, Too

Codex App 26.602 Is a Small UX Release With a Big Tell: Agents Need Observability for Humans, Too

Codex app 26.602 is not a feature-drop headline. Good. The most revealing agent releases are often the ones that make fewer promises and sand down the places where real users get hurt: startup readiness, error reporting, usage visibility, onboarding, and the UI seams around browsers, terminals, and diffs. OpenAI’

GitHub Just Put Copilot Cloud Agent Behind an API. Now Your Backlog Can Call Itself.

GitHub Just Put Copilot Cloud Agent Behind an API. Now Your Backlog Can Call Itself.

GitHub just made Copilot cloud agent callable infrastructure. That sounds like a small API preview until you remember what APIs do: they turn a product behavior into something scripts, internal portals, release systems, and cron jobs can invoke without a human opening the right screen and typing the right prompt.
