Start with the harness. Sign in later.
Start as a local tool with your own provider key. Add an account for hosted inference, cloud API keys, shared capabilities, or team policy.
Sofia CLI
The fastest path into a repository. Use local models, BYOK, or Sofia inference from the same command-line harness.
Windows PowerShell
Sofia Desktop
A focused visual workspace for sessions, trajectory, changes, tools, models, and organization context.
Prebuilt binaries, honestly scoped.
The installer covers every platform Sofia supports. Prebuilt Sofia-branded binaries are narrower, and this page tracks what actually exists rather than what is planned.
| Surface | Platforms with a prebuilt binary | Installer | Source |
|---|---|---|---|
| Sofia CLI | macOS (Apple Silicon), 0.1.2 | macOS, Linux, Windows | github.com/RuutChatCSM/sofia |
| Sofia Desktop | macOS (Apple Silicon), 0.1.5 | — | github.com/RuutChatCSM/sofia-desktop |
Windows and Linux users: run the installer above. It resolves the right asset for your platform and falls back to the upstream hosted releases when needed.
Start without a Sofia balance.
Start with a local endpoint or provider key. Add Sofia-hosted inference later without changing the harness.
| Mode | Account required | Provider key required | Sofia usage billing |
|---|---|---|---|
| Local model | No | No | No |
| BYOK | No | Yes | No |
| Sofia PAYG | Yes | No | Yes |
| Team managed | Yes | Organization managed | Depends on route |
Install first. Decide the cloud later.
That sequence is intentional.
