Keychron launches a 4-key F4 HE 8K keyboard built for vibe coding

Keychron has officially launched the F4 HE 8K keyboard, made for vibe coding. It's a single-mode magnetic switch keyboard with only 4 keys, and it comes with 11 extra keycaps so you can set up your most-used actions.

Keychron says that in vibe coding or daily work, people only repeat about four actions the most. Turning these into real keys can cut down typing effort. The keyboard also has built-in Codex and Claude presets, so AI coding tools are just one tap away.

On the hardware side, the F4 HE 8K has an ABS plastic body with an aluminum plate, per-key ARGB backlight, and an 8kHz polling rate. It uses Keychron Lime magnetic switches with custom trigger points, plus CHERRY-height PBT keycaps with dye-sublimation legends.
