This release is all about making Goose more flexible, secure, and global. By rebuilding how Goose talks to its own desktop app behind the scenes, the developers have made your chat sessions more stable and easier to manage. Whether you are a developer wanting to run AI models locally on your Mac, a student researching with the new "Scholar Sidekick" tool, or someone who prefers using Goose in Spanish or Japanese, this update makes your AI assistant much more capable and customizable.

What's new

  • More AI Brains (Providers): Goose now supports a bunch of new AI services, including Perplexity, Together AI, Databricks, Alibaba's Qwen, and xAI's SuperGrok.
  • Run Models Locally on Mac: Added support for MLX, which lets you run AI models directly on your Apple Silicon Mac without needing an internet connection.
  • Image Reading Tool: Goose can now look at and read images to help you analyze visual data.
  • Scholar Sidekick: A new built-in tool designed to help you find and read academic papers.
  • Deep Links: You can now open or resume Goose sessions directly from web links (using goose:// links).
  • Hugging Face Login: A new settings tab lets you easily log into Hugging Face (a massive library of AI models) using secure login.
  • New Languages: Added official support for Korean, Spanish, Japanese, Hindi, Russian, and Turkish, along with a language selector in the settings.

Improvements

  • Smoother App Communication (ACP): Goose now uses the Agent Connection Protocol (ACP)β€”a standardized way for the app to talk to the AIβ€”to handle tasks like loading chats, changing settings, and managing "recipes" (pre-set instructions for tasks).
  • Better Cost Tracking: Goose now tracks "cache tokens" (saved pieces of memory) so you can see exactly how much your AI queries are costing.
  • New Terminal Commands: If you use the Command Line Interface (CLI), you can now use /status to check on your session and /model to quickly switch AI models.
  • Update Control: You can now turn off automatic update downloads if you prefer to update manually.
  • Prompt Security: Added built-in protection against "prompt injection" (tricking the AI into doing something it shouldn't) for internal users.

Fixes

  • Mac Updates & Tools: Fixed issues with how Goose updates on Mac and made sure background tools can properly find "Node.js" (a software runner) on macOS.
  • Web Image Loading: Fixed a bug where Goose couldn't fetch images from certain websites because it wasn't identifying itself properly (missing "User-Agent" headers).
  • Model Settings: Fixed a bug where sending "temperature" settings (which control how creative the AI is) broke connections to ChatGPT Codex.
  • Search and Directory Fixes: You can now search for unlisted models, and Goose will properly refresh when you change your working folder.
