0.6 PUBLIC BETA // APPLE SILICON

Your Mac.
Your models.
One clear agent.

Sirius gives every project its own constellation of local AI threads—with fast Qwen inference, bounded memory, focused fx execution, and explicit control over tools.

01 // WHAT SIRIUS DOES

One project.
Many fresh stars.

Start a clean thread without losing the project. Keep it private, or let it share the useful memory and capabilities of its constellation.

01

Fast local Qwen

Streaming Qwen 3.8 through MLX Serve on Apple Silicon, with model setup and runtime health owned by Sirius.

02

Constellations

Codex-style project threads. Create a new star for a fresh start, then choose whether its memory stays private or shared.

03

Bounded memory

KITKAT and your read-only ChatGPT archive provide cited context only when it is useful—without silently merging every thread.

04

fx Agent

Turn on workspace tools and longer execution only when the task needs them. Direct chat remains direct.

05

Isolated browser

Research in a Sirius-owned browser profile, separate from your personal browser state and enabled per session.

06

Creative actions

Turn a message into a Suno track brief, LTX video prompt, ALi render sequence, memory proposal, or reviewed finance draft.

02 // THE REAL PRODUCT

Abstract outside.
Practical inside.

The constellation is not a metaphor pasted onto a chat app. It is how Sirius organizes real project threads, local models, memory scopes, tools, and visible control boundaries.

03 // THE ELASTIC ENGINE

The whole model can stay on storage.
Only useful structure wakes up.

Sirius treats a giant sparse model as addressable components. Routers select the experts required now; bounded storage reads materialize them into MLX; useful components remain warm until memory pressure asks them to leave.

04 // ONE LOCAL CREATIVE SYSTEM

Sirius connects the work.
Each app keeps ownership.

Sirius is the conversational surface. It sends typed, reviewable handoffs to the specialist app that owns the result—never an invisible cross-app mutation.

05 // EXPLICIT CONTROL

Your Mac is not a hidden tool.

fx and macOS Control are separate switches. Enable the agent without handing it your Desktop, then grant Mac control only for the turns that truly need it.

  • fx AgentWorkspace tools and managed execution
  • macOS ControlOff by default, visible when enabled
  • Browser modeIsolated and enabled per session
  • Memory scopePrivate star or shared constellation

06 // LOCAL BY DESIGN

The model lives on your Mac. The workspace belongs to your project.

Sirius is built for people who want a capable AI collaborator without turning every thought into a cloud workflow.

Local inference, deliberate tools, recoverable state. The system stays understandable even as it becomes more powerful.
