Codex in ChatGPT | AI Coding Agents for Software Engineering

Trusted by teams building ambitious software with OpenAI

Built for real development environments

Bring AI into large codebases, workflows, and the tools your teams already use.

Scale AI with confidence

Manage access, spend, adoption, and agent behavior across teams.

Move faster across the SDLC

Use Codex in ChatGPT to plan, build, review, test, deploy, and follow up on complex software work

Ready for enterprise-scale development

Codex in ChatGPT helps organizations bring AI into their development environments without giving up security, visibility, or governance.

Go from doing the work to directing it

Developers can delegate work while staying close to the code, context, standards, and review processes that matter.

GitHub Enterprise Server support

SSH on devboxes

Codex Security

Enterprise data protections

“The biggest gains came when we stopped thinking about Codex as a tool and started treating it as part of the team.”

Ryan Brady, Principal Engineer, Cisco

Lead adoption with confidence

Scaling AI across engineering requires control over access, usage, spend, and agent behavior. Codex in ChatGPT gives leaders the visibility and controls to manage adoption responsibly across teams, without slowing developers down.

Secure agent sandboxing

Usage visibility and reporting

Enterprise data encrypted in transit and at rest

No training on enterprise data by default

Bring Codex in ChatGPT into security review.

Codex helps engineering and security teams find, validate, prioritize, and remediate vulnerabilities. Teams can bring agentic assistance into security-sensitive workflows while maintaining oversight of what gets fixed and shipped.

Build, ship, and test faster

From reviewing pull requests and investigating security issues to triaging failed CI runs and documenting fixes, Codex in ChatGPT helps developers bring more context to the complex work that happens every day.

Plan

Understand large or unfamiliar codebases, trace how systems fit together, evaluate implementation options, and turn ambiguous requests into plans teams can review.

Build

Delegate feature work, refactors, migrations, and code changes while engineers stay focused on architecture, review, and high-leverage decisions.

Review

Bring Codex into pull request workflows to review changes, address comments, catch issues earlier, and help teams ship with more confidence.

Deploy

Use Codex for CI/CD follow-up, incident investigation, release prep, major fixes, and operational work so teams can resolve issues without derailing the roadmap.

Examine the database schema for my app and produce a detailed ERD.

Pull down my highest priority ticket and create a plan to implement it.

Use this mock to add a user count graph to our analytics home page.

Our goal is to implement an iOS app for our support ticket inbox. Reference the backend routes in /routes and use XCodeBuildMCP in your implementation. Only build the view for ticket agents, and don't stop until the iOS app builds successfully.

Read all of the comments on this PR and make the fixes requested, commit the changes and push up.

Prep my week from my calendar, messages and docs and generate a concise briefing with calendar highlights, priorities, watchouts, and todos.

Review survey feedback in this Google Sheet and summarize into themes with quotes [link]

Find the emails I need to respond to, summarize each in bullets with the summary bolded, include the reply inline below each bullet, and create unsent email drafts for those same replies.

Pull a list of all candidates starting in early march and load them into a Google Sheet that includes their name, role and start date. Then draft a slack message to our #[team-channel] channel summarizing the number of new hires per team. Lastly create a unique private Slack channel for each new hire using #tmp-welcome-[first_name]-[last_name]

Build attendee list from selected leaders and save it in a spreadsheet. Create the calendar invites, draft email invites, and send the Slack message. Finally, create a first-pass rooming plan and flag manual reviews.

Scan this Google Sheets spreadsheet for employees whose training completion rate is below 100%, then send each of them a Slack DM using the template in the “employee comms” tab of the linked Google Doc.
