Arc 1.6.0
Arc 1.6.0 lets you drop files directly onto a specific agent in the composer and keeps longer Local AI work moving when context fills.
Previous release
Files go straight to the work
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon.
Highlights
- Drop one or more files onto the composer, review removable attachment chips, then send them to the selected agent’s managed workspace inbox.
- Arc fits each local model’s context window to live device and model evidence, up to the 65,536-token ceiling, and shows the fitted result in Settings.
- Long Local AI turns compact older exchanges and page through large files in bounded reads while keeping the active task and recent work intact.
Fixes and refinements
- File delivery is bound to the selected room seat and rechecked against the workspace, authorized readers, and exact running daemon before anything is published.
- Model checks and runtime-path changes preserve your label, fitted context, compaction, overcommit, and step settings.
System requirements
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon.
