OpenAI’s $230 Codex Micro Keyboard lets you dial up AI power

OpenAI has decided that adjusting an AI’s thinking power should feel less like clicking through a settings menu and more like turning up a stereo. Enter the Codex Micro, a $230 mini keyboard built with keyboard maker Work Louder, made specifically for Codex users who want their AI tools within arm’s reach rather than buried in tabs.

What the dial actually does

The headline feature for Codex Micro is a rotary dial that changes how hard Codex thinks in real time. Keep it low for quick, everyday tasks. Crank it up when you need deeper reasoning. It’s a refreshingly literal fix for something that’s usually just a dropdown, and honestly, I don’t hate the idea of reasoning power becoming as simple as a volume knob.

More than just a dial

The Codex Micro isn’t a one-trick device. A small joystick lets you trigger Codex actions like reviewing a pull request or debugging code without opening a chat window. Programmable keys handle common tasks like accepting a change or starting a new session, and they double up as status lights. RGB indicators show whether an agent is thinking, running, waiting, or done, so you can glance at your desk instead of clicking through every conversation to check progress.

Is it worth $230?

With 13 mechanical switches, a joystick, a touch sensor, and a dial packed in, this is a lot of hardware built around one AI coding tool. Whether that’s justified depends entirely on how deep Codex runs in your workflow. If you’re managing multiple agents daily, dedicated buttons and status lights could genuinely save time. If you use Codex occasionally, £230 is a tough sell for a glorified shortcut pad.

For now, the point’s moot anyway. The Codex Micro is already sold out, so anyone tempted will be stuck waiting for the next restock before they can decide if this is genius or overkill.
