Baton Desktop 0.1.9 — macOS (Apple Silicon)
0.1.9 is an upgrade release: Claude Code can now use Anthropic's latest Fable 5.1, every built-in agent runtime is updated to its current version, and the user message bubble and reading size in AI conversations are refined.
Fable 5.1 in Claude Code
The model picker now offers Fable 5.1 (claude-fable-5-1), Anthropic's most capable publicly available model. It ships with a native 1M context, so there is no separate 1M variant to pick, and it supports the full reasoning ladder including the top ultracode tier.
Built-in agent runtime updates
- Claude Code 2.1.257 (Agent SDK 0.3.257)
- Codex 0.152.0
- OpenCode 1.18.26
- Cline 3.0.60
- Grok CLI 1.0.15
- Cursor SDK 1.0.30
Managed runtimes (Codex, OpenCode, Cline, Grok) are downloaded and verified by Baton. After upgrading, the new version is fetched automatically the next time you use that agent; nothing needs to be installed by hand.
Conversation polish
- User messages are now right-aligned rounded bubbles with their own fill color, no longer sharing the button hover color, tuned separately for light and dark themes.
- Conversation prose (answers and thinking) moves from 15px to 14px; the rest of the app keeps its existing sizes.
Baton will update automatically the next time you launch it, or you can download the latest version at hecara.com.
