Sirius 0.6 Beta 2

Sirius 0.6.0 Beta 2

Beta 2 promotes the verified Sirius 0.6 build used with Qwen3.8 Flash Next through MLX Serve on Apple Silicon.

What changed

• Reliable switching between native MLX and MLX Serve model profiles.
• Transactional rollback when a requested model cannot start.
• Stronger download completeness checks for large model repositories.
• Project constellations with compact neighboring stars and private or shared memory scope.
• Streaming token-usage requests so direct model replies display measured decode speed.
• Clearer local-runtime and memory-pressure diagnostics.
• Graceful handoff between recorded inference backends.

Verified working path

• Qwen3.8 Flash Next MLX Serve 4-bit loaded through Sirius.
• Direct warm replies measured up to 77 tokens per second on the development Mac Studio.
• fx workspace execution and optional macOS Control remain explicit opt-ins.
• Model switching, local chat, project stars, and per-response speed display were exercised in the installed app.

Performance varies with hardware, prompt length, model state, tool use, and memory pressure. Agent-task timing is not the same as raw model decode speed.

Requirements

• Apple Silicon Mac
• macOS 14 or newer
• Adequate storage and unified memory for the selected local model
