OpenAI has released the Codex Micro, a physical programmable keyboard built in collaboration with Work Louder, designed specifically to control Codex and GPT-4.5 Sol during software development sessions.
The device handles six distinct workflow functions without requiring the developer to leave the editor: voice dictation, plan mode and reasoning controls, task switching, permission request handling, and follow-up prompt queuing. The demo walks through a complete build of a word game, showing each function in sequence with real timestamps, which means the pacing and friction points are visible, not just the highlight reel.
The hardware angle is what makes this worth reading in full. OpenAI is betting that keyboard-level physical controls reduce context-switching cost enough to change how developers interact with AI agents. The customization segment at 1:49 suggests the key mappings are user-configurable. Units are available now at openai.com/supply.
