Baton Desktop 0.1.15 — macOS (Apple Silicon)

0.1.15 adds Claude Opus 5.5 and GPT-6-Sol / GPT-6-Luna, upgrades every bundled Agent SDK, and reworks provider settings: model pickers become dialogs, and the auth header now follows the API protocol by default.

Models and Agents

  • Claude Code: adds Opus 5.5 (1M context). Sonnet 5 and Opus 4.7 gain the xhigh and ultracode effort tiers.
  • Codex: adds GPT-6-Sol and GPT-6-Luna, and new sessions default to GPT-6-Sol. GPT-5.4-Mini is retired and removed from the list; a session that still had it selected switches to the default model the next time it opens. The recommended utility model is now GPT-5.6-Luna.
  • Every bundled SDK and managed CLI moves to its latest version: Claude Agent SDK, Codex, OpenCode, Cursor, Grok, and Cline.

Baton Agent (BYOK)

  • With the Anthropic Messages API, the auth header setting now actually takes effect: chat requests and the connection test send the same header.
  • A custom provider's auth header defaults to Auto, which picks the header that matches the API protocol. To set it by hand, open Advanced.
  • When a custom provider's connection test fails authentication, Baton tries the other header styles; if one works, it is saved automatically and you get a notice.
  • Fetch models opens in its own dialog instead of inside the model card.
  • "Install as terminal command" is removed. Terminal commands can still be created on the Profiles page.

Settings

  • Default model and utility model share one dialog: pick a provider, then a model. The utility model button shows only the model name.
  • In the connected-provider list, each row now has a switch that controls whether the provider is used in Baton AI; the provider page no longer repeats this setting. Provider icons in the list sit on a rounded tile.
  • The "live model discovery is unavailable" banner and the empty model-list hint are gone.
  • The Run Dock drops its shadow in favor of a subtle outline.

Baton will update automatically the next time you launch it, or you can download the latest version at hecara.com.
