@onyx-app-group onyx-app-group released this 15 Sep 04:15

Onyx Code now runs the newest local models. The bundled inference engine is updated to llama.cpp 0.4.1, so this year's model families load straight from Browse Models.

Downloading

If you're installing manually:

macOS

  • Apple Silicon Mac (M1 or newer): download OnyxCode-darwin-arm64.dmg (smaller, native).
  • Intel Mac, or unsure: download OnyxCode-darwin-universal.dmg (runs on both).

Open the .dmg and drag Onyx Code to /Applications/. Both macOS downloads are signed and notarized by Apple, so they pass Gatekeeper and open without security warnings.

Linux (x64)

  • Debian / Ubuntu: download OnyxCode-linux-x64.deb and install it with sudo apt install ./OnyxCode-linux-x64.deb.
  • Other distributions: download OnyxCode-linux-x64.AppImage, make it executable (chmod +x), and run it. On Ubuntu 24.04 (which lacks libfuse2) run it with --appimage-extract-and-run.

Windows (x64)

Install with winget: winget install OnyxCode (recommended). It runs through Microsoft's App Installer (a trusted Microsoft Store app) with a package listing reviewed in Microsoft's community winget repository, so it verifies the download and gives a smoother first-run experience. The same installer (OnyxCode-win32-x64-winget.exe) is also attached here for manual download; note it is not code-signed yet either way, so Windows may still show an "Unknown publisher" warning. A code-signed installer is planned for a later release.

The *-autoupdate.zip, darwin-*.json, linux-x64.json and win32-x64.json files are plumbing for Onyx Code's
built-in auto-updater. They are not designed for manual install and will give
you a worse first-run experience than the download above.

What's New

Changed

  • Runs the newest local models. The bundled engine is now llama.cpp 0.4.1. Model families released this year load directly from Browse Models, including JetBrains Mellum 2, DeepSeek V4, Meta Muse Glimmer, Kimi K3, Tencent HY4 and MiniMax M3, alongside everything that already worked.
  • Help links that go somewhere useful. Report Issue, the licence page and the other support links inside the app now open the public GitHub Discussions and Issues pages and the terms page on onyxcode.app.
  • A cleaner Linux package. The Debian package now carries Onyx Code's own maintainer details and keeps your apt sources exactly as they were.

System Requirements

  • macOS 11 (Big Sur) or later.
  • Apple Silicon (M1 or newer) or an Intel Mac. The Universal download runs natively on both.

Installing

  1. Download the .dmg that matches your Mac (see "Downloading" above).
  2. Open it and drag Onyx Code into your Applications folder.
  3. Launch it from Applications. Because the build is notarized, it opens without a security prompt.

Verification

This build is signed and notarized by Apple. macOS verifies it on first launch, so it opens as an app from an identified developer without security warnings.
