March 4, 2026 replace: The Codex app is now to be had on Home windows.
Lately, we’re introducing the Codex app for macOS—a formidable new interface designed to easily organize more than one brokers directly, run paintings in parallel, and collaborate with brokers over long-running duties.
We are additionally excited to turn extra other folks what is now conceivable with Codex. For a restricted time we are together with Codex with ChatGPT Loose and Pass, and we are doubling the speed limits on Plus, Professional, Industry, Endeavor, and Edu plans. The ones upper limits practice in all places you utilize Codex—within the app, from the CLI, for your IDE, and within the cloud.
The Codex app adjustments how tool will get constructed and who can construct it—from pairing with a unmarried coding agent on focused edits to supervising coordinated groups of brokers around the complete lifecycle of designing, construction, delivery, and keeping up tool.
Since we introduced Codex in April 2025, the best way builders paintings with brokers has basically modified. Fashions are actually in a position to dealing with complicated, long-running duties finish to finish and builders are actually orchestrating more than one brokers throughout initiatives: delegating paintings, working duties in parallel, and trusting brokers to tackle considerable initiatives that may span hours, days, or weeks. The core problem has shifted from what brokers can do to how other folks can direct, supervise, and collaborate with them at scale—current IDEs and terminal-based gear don’t seem to be constructed to reinforce this manner of running.
This new method of creating coupled with new type functions calls for a special more or less software, which is why we’re introducing the Codex desktop app, a command middle for brokers.
The Codex app supplies a targeted house for multi-tasking with brokers. Brokers run in separate threads arranged through initiatives, so you’ll seamlessly transfer between duties with out dropping context. The app permits you to assessment the agent’s adjustments within the thread, remark at the diff, or even open it for your editor to make guide adjustments.
It additionally comprises integrated reinforce for worktrees, so more than one brokers can paintings at the similar repo with out conflicts. Each and every agent works on an remoted replica of your code, permitting you to discover other paths while not having to trace how they affect your codebase. As an agent works, you’ll take a look at adjustments in the neighborhood or let it proceed making development with out touching your native git state.
The app selections up your consultation historical past and configuration from the Codex CLI and IDE extension, so you’ll in an instant get started the usage of it along with your current initiatives.
Codex is evolving from an agent that writes code into one who makes use of code to get paintings carried out in your pc. With abilities(opens in a brand new window), you’ll simply prolong Codex past code technology to duties that require collecting and synthesizing knowledge, problem-solving, writing, and extra.
Talents package directions, sources, and scripts so Codex can reliably connect with gear, run workflows, and whole duties in step with your group’s personal tastes. The Codex app features a devoted interface to create and organize abilities. You’ll be able to explicitly ask Codex to make use of particular abilities, or let it robotically use them in keeping with the duty handy.
We requested Codex to make a racing sport, whole with other racers, 8 maps, or even pieces avid gamers may just use with the distance bar. The use of an symbol technology ability(opens in a brand new window) (powered through GPT Symbol) and a information superhighway sport construction ability(opens in a brand new window), Codex constructed the sport through running independently the usage of greater than 7 million tokens with only one preliminary person instructed. It took at the roles of clothier, sport developer, and QA tester to validate its paintings through in truth enjoying the sport.
We’ve integrated the sport, in addition to the instructed and abilities used to create it, under. You’ll be able to additionally check out previous iterations to look how Codex progressed it because it labored for longer.
The sport was once created through Codex with the develop-web-game ability the usage of this instructed that we have summarized for readability:
Put into effect Voxel Pace as a three-D voxel kart racer the usage of 3.js, with precisely one mode: Unmarried Race (at all times 3 laps, 1 human vs 7 CPU, and all 8 tracks to be had in an instant with out a development). Construct a minimum pre-race waft with simplest: Monitor (8), Personality (8), Problem (Sit back/Usual/Imply), non-compulsory Replicate Mode, non-compulsory Permit Clones, and Get started Race, plus an Choices menu and an in-race pause menu (Resume / Restart / Hand over). Create an arcade riding type with responsive dealing with, forgiving glancing wall hits, significant drifting as the primary ability, and a drift-charge formulation that produces actual spice up tiers (Tier 1 0.7s, Tier 2 1.1s, Tier 3 1.5s) whilst retaining baseline velocity “fast-but-readable” and pack passing consistent on broad roads. Put into effect precisely 8 pieces with one-item capability, refined position-weighted distribution, and delicate results (max lack of keep watch over ≤1.2s, max guidance disabled ≤0.6s) that create goofy chaos with out arduous stuns, plus off-road slowdowns which are decreased through 50% all the way through boosts. Outline the 8 characters with their given stats and AI inclinations, enforce CPU issue presets and track-authored racing/variation splines, waft zones, and danger avoidance so AI makes use of multi-lane width for blank overtakes, and send HUD/audio necessities (role, lap/ultimate lap banner, minimap, merchandise slot, timer/splits, readable SFX, and one tune loop in step with tune).
Codex was once then incessantly reprompted from a random listing of ten generic activates to stay running at the difficulty. An instance of one of the vital activates is:
Your activity is so as to add new options so the sport suits the unique extra intently. First, play the sport and establish what’s lacking vs. the unique. Then select a couple of lacking options and enforce them. After every characteristic, totally take a look at it through enjoying the sport and make sure it really works. When you realize any insects whilst enjoying, prioritize solving them too.
At OpenAI, we’ve constructed masses of abilities internally to lend a hand more than one groups with a bit of luck delegate paintings to Codex that might differently be arduous to outline persistently—from working evals and babysitting coaching runs to drafting documentation and reporting on expansion experiments.
The Codex app features a library of abilities for gear and workflows that experience change into fashionable at OpenAI, with a couple of highlighted under. You’ll be able to in finding the total listing within the open supply repo(opens in a brand new window).
- Put into effect designs: Fetch design context, property, and screenshots from Figma(opens in a brand new window) and translate them into production-ready UI code with 1:1 visible parity.
- Organize initiatives: Triage insects, tune releases, organize group workload, and extra in Linear(opens in a brand new window) to stay initiatives transferring.
- Deploy to the cloud: Have Codex deploy your information superhighway app creations to fashionable cloud hosts like Cloudflare(opens in a brand new window), Netlify(opens in a brand new window), Render(opens in a brand new window), and Vercel(opens in a brand new window).
- Generate photographs: Use the symbol technology ability(opens in a brand new window) powered through GPT Symbol to create and edit photographs to make use of in internet sites, UI mockups, product visuals, and sport property.
- Construct with OpenAI APIs: Reference up-to-date documentation(opens in a brand new window) when construction with OpenAI APIs.
- Create paperwork: A suite of abilities for studying, developing, and enhancing PDF(opens in a brand new window), spreadsheet(opens in a brand new window), and docx(opens in a brand new window) recordsdata with skilled formatting and layouts.

Whilst you create a brand new ability within the app, Codex can use it anyplace you’re employed: within the app, CLI or for your IDE extension. You’ll be able to additionally take a look at abilities into your repository to cause them to to be had to your whole group. Learn extra about sharing abilities the usage of group config right here(opens in a brand new window).
With the Codex app, you’ll additionally arrange Automations that allow Codex paintings within the background on an automated agenda. Automations mix directions with non-compulsory abilities, working on a agenda you outline. When an Automation finishes, the consequences land in a assessment queue so you’ll soar again in and proceed running if wanted.
At OpenAI, we’ve been the usage of Automations to take care of the repetitive yet essential duties, like day by day factor triage, discovering and summarizing CI disasters, producing day by day liberate briefs, checking for insects, and extra.
Putting in an automation to periodically create new abilities
Builders have other personal tastes in how they paintings with an agent. Some need a blunt, execution-focused spouse; others favor extra communicative, attractive interactions. Codex now we could builders choose from two personalities—a terse, pragmatic taste and a extra conversational, empathetic one, with none exchange in functions, to suit the way you favor essentially the most. Simply use the /character command within the app, CLI, and IDE extension.
We’re integrating safety through design throughout all of the Codex agent stack. The Codex app makes use of local, open-source(opens in a brand new window) and configurable system-level sandboxing identical to within the Codex CLI. Through default, Codex brokers are restricted to enhancing recordsdata within the folder or department the place they’re running and the usage of cached information superhighway seek, then requesting permission to run instructions that require increased permissions like community get entry to. You’ll be able to configure laws(opens in a brand new window) to your mission or group that permits sure instructions to robotically run with increased permissions.
The Codex app is to be had beginning lately on macOS. Somebody with a ChatGPT Plus, Professional, Industry, Endeavor or Edu subscription can use Codex around the CLI, information superhighway, IDE-extension and app with their ChatGPT login. Utilization is integrated in ChatGPT subscriptions, with the choice to buy further credit if wanted.
For a restricted time, Codex can be to be had to ChatGPT Loose and Pass customers to lend a hand construct extra with brokers. We’re additionally doubling fee limits for current Codex customers throughout all paid plans all the way through this era.
Enterprises and builders more and more depend on Codex for end-to-end construction. For the reason that release of GPT‑5.2‑Codex in mid-December, general Codex utilization has doubled, and prior to now month, greater than 1,000,000 builders have used Codex. We’ll proceed to amplify the place and the way builders can use Codex, together with making the app to be had on Home windows, pushing the frontier of type functions, and rolling out sooner inference.
Inside the app, we’ll stay refining multi-agent workflows in keeping with real-world comments, making it more uncomplicated to control parallel paintings and transfer between brokers with out dropping context. We’re additionally construction out Automations with reinforce for cloud-based triggers, so Codex can run incessantly within the background—no longer simply when your pc is open.
Codex is constructed on a easy premise: the whole thing is managed through code. The easier an agent is at reasoning about and generating code, the extra succesful it turns into throughout all kinds of technical and data paintings. But a key problem lately is the space between what frontier fashions are in a position to and the way simply other folks can use them in follow. Codex is designed to near that hole through making it more uncomplicated to direct, supervise, and practice the total intelligence of our fashions to genuine paintings. We’ve all for making Codex the most efficient coding agent, which has additionally laid the root for it to change into a robust agent for a large vary of information paintings duties that stretch past writing code. We’re excited to look what you construct with Codex!
