System requirements
Everything that touches your code runs in your browser or on your desktop. What a given device can do depends on its browser, its memory and its GPU. This table is the honest version, including what is not there yet.
| Platform | Needs | What you get today |
|---|---|---|
| Chrome / Edge, desktop | 64-bit; 4 GB RAM for OIOXO Light, 8 GB for Prime or a 3B open model; ~2 GB free disk per model. WebGPU where the browser has it. | The full room. On-device models on CPU or GPU, Open folder in place, Preview, Changes, Git through the proxy, TypeScript / Python / CSS / HTML / JSON language services. CPU-only machines work; they are slow. |
| Firefox, desktop | The same memory; a machine with 8 or more threads runs the CPU tier acceptably. Open-folder-in-place is not available — use Import or Just try it. | Everything else, including on-device models. |
| Safari, macOS | — | Your key only today. The on-device engine does not run on Safari yet; add a key and the rest of the room works. |
| Android phone (Chrome) | 8 GB RAM for OIOXO Light (Mobile), ~545 MB download. | Watch, prompt, light edits, on-device Light. A companion, not the full IDE. |
| iPhone / iPad | — | Your key only. Watch, prompt, light edits with a key. |
| Windows 10 / 11 desktop app | x64, 8 GB RAM. For the native tier: an NVIDIA GPU with 6 GB or more VRAM (the CUDA engine, ~484 MB, downloads on first use). AMD and Intel machines run CPU-first. | The room plus a real terminal, bundled language plugins, the native GPU tier, self-update. |
| macOS desktop app | Apple Silicon or Intel, 8 GB RAM. | The room, terminal and language plugins. Models run on the same tiers as the browser today; there is no native Metal engine yet. |
| Linux | — | No installer yet. The web tier in Chrome or Firefox is the full product on Linux. |
Disk and storage
Models live in browser storage (OPFS) or the desktop app’s data folder. Settings → Models & keys shows the storage meter and lets you delete a model. Projects marked “in this browser” live in the same private storage — export a zip before clearing site data. A folder on disk is yours on disk.
Note
OIOXO checks the device before offering a model: a model that does not fit in memory is shown but not recommended, and one that cannot fit is not offered. If a download you did not choose ever starts, that is a bug — report it.
