TL;DR
OpenAI is selling a $200 ModRetro Chromatic handheld bundled with a programmable Codex Cartridge for making and playing Game Boy-style games. It went on sale November 9, 2026; the product page showed “Restock soon” on November 10 and listed November 19 as the expected restock date. Unit sales and the timing of the restock are not known.
OpenAI began selling the $200 ModRetro Chromatic: Codex Edition through its Supply Co. shop on November 9, pairing a retro handheld with a programmable cartridge intended for games made using its Codex coding agent. On November 10, the product page said “Restock soon” and listed November 19 as the expected restock date, though OpenAI says dates may change.
The clear-shell handheld is a ModRetro Chromatic that plays Game Boy and Game Boy Color cartridges. The Codex Edition package includes one programmable Codex Cartridge and three AA batteries. Its listed display is a 2.56-inch, 160-by-144-pixel IPS screen with scratch-resistant Gorilla Glass. The device also has a speaker and a 3.5mm headphone jack.
OpenAI’s product page describes the intended workflow as “Build it with Codex. Play it on Chromatic.” Users can describe a game, work with Codex and the ModRetro Chromatic plugin, refine the project in GB Studio, export a ROM and load it onto the cartridge. OpenAI also lists browser play and streaming from a computer to the handheld as ways to test a game before writing it to a cartridge.
Getting started requires updating the handheld’s firmware, entering an activation code to unlock Developer-Mode, installing the Codex app and adding the Chromatic plugin. The developer guide warns that writing a new ROM erases the cartridge’s existing game and may erase its save data; the installer does not back up the cartridge. OpenAI says the bundle is available for shipment to the United States, Canada, Australia, New Zealand, Japan, the United Kingdom and the European Union.
An AI Prompt Handheld?Meet OpenAI’s $200 Codex Edition
OpenAI pairs a retro handheld with a programmable cartridge for making and playing Game Boy-style games with Codex. Its appeal depends on both availability and buyers’ interest in creating games.
What comes in the bundle
The edition combines familiar retro hardware with a cartridge designed for game creation.
ModRetro Chromatic
A clear-shell device that plays Game Boy and Game Boy Color cartridges.
Programmable cartridge
The package includes one Codex Cartridge for loading games made with the workflow.
Retro-sized screen
A 2.56-inch, 160-by-144-pixel IPS display with scratch-resistant Gorilla Glass.
From idea to handheld
OpenAI’s proposed workflow connects its coding agent to game-building tools and physical hardware.
Work with Codex and the Chromatic plugin to create a game.
Use GB Studio, browser play or computer-to-handheld streaming to test it.
Export a ROM and write it to the Codex Cartridge.
Before you start
The creation tools require setup, and cartridge data needs special care.
- Update the handheld firmware and enter the activation code to unlock Developer-Mode.
- Install the Codex app and add the Chromatic plugin.
- Writing a new ROM erases the cartridge’s existing game and may erase save data.
- The installer does not back up the cartridge.
What buyers should weigh
The Codex Edition is a physical showcase for making games, not evidence of broad demand for Codex.
- A programmable cartridge gives game creation a tangible result.
- OpenAI lists browser-playable games and downloadable ROMs made with Codex.
- Unit sales, stock levels and future restock timing are not known.
- The listed restock date may change; the listing also says non-defective items cannot be returned.
A Physical Showcase for Codex
The handheld gives OpenAI a physical demonstration of Codex: an AI coding tool can be used to make a small game that runs on dedicated hardware, rather than producing only code on a computer screen. The cartridge workflow makes the result tangible and gives buyers a specific project to try, while the plugin connects the device to OpenAI’s software.
That makes the purchase more than a conventional retro-console sale, but the product still depends on the buyer’s interest in making games and using Codex. The handheld itself plays existing Game Boy and Game Boy Color cartridges; the advertised creation workflow is the distinctive part of this edition. OpenAI has not provided sales figures or evidence that the bundle measures broader demand for its coding tools.
The price also matters. ModRetro’s store listed a transparent Chromatic bundled with Tetris for $149.99 on November 10, while other Chromatic-and-Tetris bundles started at $199.99. Supply Co.’s Codex Edition costs $200 and lists a programmable cartridge, but its page does not mention Tetris. The comparison is not a like-for-like feature assessment, but it gives buyers a reference point for the price.

From DevDay Giveaway to Store
The Codex Edition follows an earlier DevDay version. Supply Co. says the device was first introduced as a DevDay exclusive and calls it a “standout favorite.” GIGAZINE reported that the DevDay version was handed to attendees at OpenAI’s developer conference on September 29, 2026, the same day ModRetro announced the collaboration on X. OpenAI now describes the retail model as “back with a new look.”
OpenAI has framed Supply Co. as more than an employee merchandise shop. The source material quotes the company describing its next phase as “collaborations, experiments, and physical expressions of research energy.” That is the company’s own positioning, not independent evidence of how the product will affect Codex adoption. OpenAI says it has published 13 Codex-made Chromatic games that can be played in a browser or downloaded as ROMs; the product page highlights a puzzle game, a dungeon crawler and a rhythm game.
The package does not include every accessory. Supply Co. lists a Codex Edition carrying case for $35 and an additional Codex Cartridge for $50. The extra cartridge comes with an activation code for Chromatic Developer-Mode, which OpenAI says is limited to two devices and exclusive to the Codex Edition. The listing says non-defective items cannot be returned; ModRetro, rather than OpenAI, handles warranty and support.

Sales, Stock and Support Terms
OpenAI has not disclosed how many units were made, how many sold or whether the “Restock soon” message reflects a complete sellout. The November 19 date is an estimate, and the company says restock dates can change. The supplied information also does not clarify how many units will be available or whether the device will ship beyond the listed regions.
Other practical details are not established by the listing. It does not give a schedule for future Codex Edition restocks or specify how long the Developer-Mode activation arrangement will be supported. The product’s no-return rule for non-defective items and ModRetro’s responsibility for warranty and support are stated, but the source material does not provide further detail about the terms or the process for getting assistance.
OpenAI’s and ModRetro’s product descriptions also do not establish that every game idea can be completed successfully through the workflow, or how accessible the creation tools are to people without coding or game-development experience. Those questions may become clearer as buyers use the device, but the announcement itself offers no independent evaluation.
Expected Restock and Buyer Testing
The next stated milestone is the expected November 19 restock on Supply Co. OpenAI cautions that the date may change, so buyers will need to check the product page for current availability. The company has not announced a wider release schedule or shared a unit count.
For buyers who obtain the device, the immediate next steps are to update its firmware, activate Developer-Mode and install Codex and the Chromatic plugin. They should also heed the cartridge warning: writing a ROM can erase the current game and its saves, and the installer does not create a backup. Any further assessment of the product’s appeal will depend on stock availability, the creation workflow in practice and information OpenAI may later provide about sales or support.
