YOUR AI AGENT CONTROLLER

F4 HE 8K Vibe Coding Keypad

The Keychron F4 HE 8K is a four-key controller for working with AI. Send the prompt. Dictate the next one. Accept the change. Reject the bad idea. Each action is one press, so you stay in the review-and-refine loop instead of hunting for shortcuts across a full keyboard.

FOUR KEYS. FOUR MOMENTS.

The Inner Loop, On Real Keys

Working with an AI assistant collapses into a few moves you repeat all day: send a prompt, speak the next one, approve what came back, or throw it out and go again. The F4 gives each move its own key with an icon cap to match, so the loop runs through your fingers, not through menus.

Off the clock, the same four keys handle whatever you repeat most: copy/paste, meeting mute, window snapping, or a macro chain.

MAGNETIC ADVANTAGE

One Key. Multiple Actions

One fixed ball position can't fit every hand. With T1 HE, adjust the 34 mm trackball to match your hand size, thumb reach, and grip — less awkward stretching, less unnecessary tension, and a much easier adjustment for trackball newcomers. The ball is also removable, making routine cleaning quick and easy.

Thanks to Dynamic Keystrokes (DKS), you can now assign up to 4 distinct actions per key based on press depth. A light press moves your character, a deeper press makes them run, and releasing the key enables additional commands. This layered control lets you execute multiple moves with ease.

WEB-BASED. NO DRIVERS

Pick a Preset, or Just Describe It

Plug in, open launcher.keychron.com in your browser, and the F4 is ready to configure — no download, no driver. Choose a ready-made preset for codex or claude and go, or remap the keys, record macros, and set how far each key travels.

The codex and claude presets each include a key for voice input. Prefer to just say it? The built-in AI assistant sets keys up from a plain-language request.

*The F4 does not have a built-in microphone. For voice input, use your computer's built-in microphone or an external microphone.

Stored on the Device

Set It Once. It Travels With You.

Your layout saves to the F4 itself. Plug into a different computer and your four actions are already there. No account, no sync, no setup twice.

MAKE IT YOURS

15 Icon Keycaps. Build Your Loadout.

Every key you program gets a cap to match. Pick from 15 icon legends in Cherry-profile dye-sub PBT. Set up a loadout for the way you work.

RGB, PUT TO WORK

Read Your Keys at a Glance

With per-key RGB, give each key a color that matches its job, such as green to accept, red to reject, or choose from 22 backlight effects to make your setup your own.

FROM WORK TO PLAY

Four Keys for Your Go-To Moves

Map the keys to your in-game moves, such as weapon swaps, abilities, push-to-talk, and tune how deep each press registers. Magnetic switches and wired 8,000 Hz polling keep every action responsive.

Magnetic Switch Control

Tune Every Press to Match the Action

The F4 HE 8K comes with pre-lubed Keychron Ultra-Fast Lime Magnetic Switches for smooth, stable keystrokes. These switches also let you set each key's actuation point from 0.20 to 3.30 mm with 0.1 mm sensitivity. Choose a shallower setting to register a press sooner or a deeper setting for more deliberate input.

Wired 8K Polling Rate

Instant Control, Ultra-Fast Response

With a wired polling rate of 8,000 Hz, the F4 HE 8K can report key inputs to your computer up to 8,000 times per second. It delivers responsive input whether you’re running a shortcut at work or switching weapons mid-match. Pair it with an 8K-rated cable like the Keychron Coiled Aviator Cable 8K since standard USB-C cables cap the polling rate.

*8,000 Hz polling requires a USB-C cable that supports an 8K polling rate.

OFF THE CLOCK

A Desk Toy That Travels

Need a break? The F4 taps like a fidget piece — smooth keystrokes, soft sound. And at 44.94 mm square with a lanyard, it leaves the desk as easily as it lives on it: clip it to your bag and take your shortcuts along.
