Cosmo Studio v1.1.2 Release Hero

We are thrilled to announce the release of Cosmo Studio v1.1.2. This update brings a massive leap forward in how you interact with AI, introducing highly requested features like Personas, MCP support, and a dramatically improved messaging experience.

Whether you're a developer, a power user, or just getting started with AI, v1.1.2 is designed to make your workflow faster, smarter, and more intuitive.

✨ What's New in 1.1.2?​

👥 Personas​

Custom tailored AI experiences are now here! Create and switch between specialized Personas to give your AI assistants unique contexts, instructions, and behaviors. Whether you need a code reviewer, a creative writer, or a technical guide, Personas have you covered.

🧩 MCP (Model Context Protocol)​

Expanding the horizons of what your AI can do! v1.1.2 introduces support for the Model Context Protocol, allowing for deeper integration and richer context sharing between models and external data sources.

⌨️ Commands​

Efficiency is at the heart of Cosmo Studio. Use a suite of Commands to quickly navigate through frequently used prompts and actions.

🌐 Expanded Provider Universe​

We've added support for a wide array of new providers, giving you the freedom to choose the best model for ogni task:

  • xAI / Groq / Mistral
  • Moonshot / DeepSeek / Perplexity
  • Cohere / LMStudio / HuggingFace

💬 Improved Chat & Messaging UX​

We've improved the messaging experience to make it more transparent and controllable:

  • 🧠 Thinking First: Models that support "thinking" will now show their reasoning process before displaying the final message.
  • 🏷️ Model Labels: Each message now clearly displays the name of the model that generated it.
  • 🛑 Stop Streaming: Take control! You can now stop a model's response mid-stream.
  • 📊 Token Usage: Get detailed insights into the token consumption of each model directly in the chat.

🛠️ Performance & Quality​

Under the hood, we've been working hard to make Cosmo Studio more stable and reliable:

  • General Fixes: Improvements to Personas, Provider pages, and UI formatting.
  • Message Handling: Enhanced encryption fallbacks and fixes for local chat history updates.
  • Refactoring: Upgraded dependencies and improved testing across core, main, and renderer modules.
  • macOS Signing: Fully signed builds for macOS for a smoother installation experience.
