Compatibility and versions
Versions used in these guides
Aventail is the current brand. The runtime is Aventail Link from version 2.x onward; version 1.x is Locai Link (Legacy Aventail). Existing commands, file paths and service addresses keep their original spelling until the corresponding service changes.
The current macOS installation guide covers Aventail Link 2.0.0 on macOS 26.6.2, Apple Silicon. It installs for the current user and uses the aventail command. The development-account walkthrough downloaded Llama 3.2 3B Instruct Q4_K_M (2.0 GB), started serving on port 8100, and returned a successful local chat-completions response.
The earlier Control and Workspace examples were tested with Locai Link (Legacy Aventail) 1.3.2 Alpha and Gemma 4 (X-Small) as a GGUF model. The Aventail local API test does not by itself verify Workspace browser access or other integrations.
Current packages
Download Link for macOS (Apple Silicon). This is the production release. For a development or staging account, use the download offered by that Control environment.
The production release host publishes these packages for Aventail Link 2.0.0:
| Platform | Desktop | Headless |
|---|---|---|
| macOS Apple Silicon (ARM64) | .pkg | .tar.gz |
| Linux x64 | .AppImage | .tar.gz |
| Windows x64 | .exe | .zip |
Use macOS desktop setup, Linux headless installation, or the shell and PowerShell commands. The current release does not publish Intel Mac or Linux ARM/Raspberry Pi packages. The Windows installer selects x64 under ARM emulation; there is no native Windows ARM package.
Choose the correct release environment
| Control environment | Installer and release host |
|---|---|
| Production | https://get.aventail.co.uk |
| Development | https://dev.get.aventail.co.uk |
| Staging | https://staging.get.aventail.co.uk |
Use the complete command or download from your Control environment. It pairs the release host with the matching management API through LINK_API_BASE; do not change only the hostname in a copied command. The local model API remains separate, normally on port 8100.
On 2 October 2026, production's /releases/latest.json reported 2.0.0, development reported 2.0.1, and staging had no published latest release. These are dated observations, not fixed version pins. The screenshots document the earlier development 2.0.0 walkthrough; newer releases can differ. Linux and Windows package availability has been checked, but those installation journeys have not been tested on devices for these guides.
get.locai.co.uk remains a compatibility alias used by some 2.0.0 release metadata. It now serves Aventail releases, not a pinned 1.x installer. For legacy packages, use the dated release below.
Locai Link (Legacy Aventail) 1.3.2 packages
The 1.3.2 release publishes these packages:
| Platform | Package |
|---|---|
| macOS Apple Silicon | Desktop .pkg and headless archive |
| Linux x64 | Headless archive |
| Windows x64 | Headless archive |
Check release assets for your exact operating system and architecture before installation. An installer recognising an architecture does not mean a prebuilt package exists for it. This release's assets do not establish a desktop Linux, Intel Mac or Raspberry Pi installation path.
Model compatibility
| Workload | Format / runtime to check |
|---|---|
| Language generation | GGUF compatible with Link's language-model engine |
| Image or audio classification | TensorFlow Lite model with the required pipeline inputs |
| Audio transcription | Model and engine supported by the transcription plugin |
A file being accepted for upload does not prove it can execute on a device. Confirm model architecture, task, engine support, memory and disk space separately. Download size is not the memory requirement.
Use a shared model for your first deployment. For a custom model, see model management.
Release history
Link release notes describe dated changes. Documentation release numbers refer to the docs, not a universal product version.
