Called the Codex Micro, the device was created in collaboration with specialist keyboard maker Work Louder and is sold through OpenAI's Supply Co. store. OpenAI describes it as a "command center for agentic work," although "keyboard" is slightly generous, as with only 13 mechanical switches, the device is really a programmable macro pad designed to sit beside a normal keyboard.

OpenAI built the device specifically for Codex users who increasingly find themselves supervising several AI agents and coding tasks at once.

The pad features 13 mechanical keys, including six translucent Agent Keys that can each be linked to a different Codex conversation. Pressing one of the agent keys immediately opens the corresponding chat. Each key uses live RGB lighting to show whether its assigned agent is idle, working, waiting for input, finished, or has encountered an error. This allows users to check the progress of several tasks at a glance instead of repeatedly opening different chats to see whether Codex has completed them.

The other six Command Keys come labeled and preconfigured for frequently used actions such as starting a new chat, approving or rejecting a request, activating push-to-talk, and sending a prompt. Users can remap them to other Codex functions and replace the keycaps with matching icons from the additional set included with the device. Hitting the push-to-talk button activates and uses the microphone connected to the user's computer, as the Codex Micro doesn't come with a microphone.

The device also features a small joystick, likely the 13th key, that can trigger reusable Codex Skills and common workflows such as debugging an error, reviewing a pull request, or refactoring code. Perhaps the Codex Micro's most interesting feature is a rotary dial that lets the user adjust the agent's reasoning level depending on the difficulty of the task. Together, the controls turn what would normally involve several clicks and chat switches into single physical actions, making it easier to keep multiple agents moving without constantly interrupting the main coding workflow.

The hardware connects through Bluetooth or USB-C and supports Mac and Windows. The body combines CNC-machined polycarbonate and aluminum with PBT and polycarbonate keycaps. Buyers can choose clicky or silent mechanical switches. The Codex Micro is not really new hardware. Peel off the branding, and it's Work Louder's existing Creator Micro 2 with the same 13 mechanical switches, rotary encoder, planar joystick, and touch sensor, simply remapped for OpenAI.
