What's New in Version 0.662.0

Released on December 21, 2025

This release brings a redesigned chat experience, revamped orchestrators with API access, model improvements, enhanced agent tools, and a reorganised AI API! 🚀

💬 Chat Improvements​

Switch Agents Mid-Conversation​

You can now seamlessly switch from one agent to another within the same conversation using the # mention syntax.

How It Works:

  • Type "#" followed by the agent name to mention which agent should handle the next turn
  • Continue your conversation flow without starting a new chat
  • Perfect for complex workflows requiring different agent expertise

Optimised Design for Long Conversations​

We've reorganised the chat UI to make better use of screen real estate, especially during extended conversations with agents.

🎯 Orchestrators Revamped​

Enhanced Planning & Orchestration​

All orchestrators have received significant improvements to their planning and orchestration capabilities.

What's New:

  • Better Planning - More intelligent task breakdown and execution strategies
  • Improved Orchestration - Enhanced coordination across all orchestrator types
  • API Access - Now available programmatically via a dedicated SSE endpoint (/planner)
  • New UX - Aligned with the newly released Agentic Tooling animations for a smoother experience

🤖 Model Updates​

Mystica & Mystica 1.5 Enhanced​

Both Mystica and Mystica 1.5 have been upgraded with:

  • Improved Intelligence - Better reasoning and comprehension
  • Enhanced Agentic Capabilities - More effective tool use and task execution
  • Coding Expertise - Significant improvements in code generation and understanding

GLM 4.6 Released​

Introducing GLM 4.6 featuring:

  • Extra Fast Inference - Optimised for speed without compromising quality
  • Reasoning Capabilities - Enhanced logical thinking and problem-solving

🔧 Agent Tools​

Basic Auth Support​

We've introduced Basic Authentication as an authorisation type for agent tools, enabling integration with legacy products in secure environments.

Why This Matters:

  • Legacy System Integration - Connect to older systems that only support Basic Auth
  • Enterprise Compatibility - Work with established enterprise infrastructure

Security Note: Basic Authentication transmits credentials in a reversible format. When using Basic Auth, ensure your network is properly secured!

This ensures credentials remain protected in transit even when using this authentication method.

🔌 API Reorganisation​

Enhanced AI API Capabilities​

We've reorganised the AI API with revamped endpoints for Searcher, Embedder, and Tokenizer utility services.

What's New:

  • Expanded Functionality - More features exposed programmatically
  • Business & Enterprise Focus - Designed for seamless integration into business workflows
  • Better Structure - Cleaner, more intuitive API organisation

📋 Summary​

This update includes:

  • Chat UI - Reorganised layout + agent switching with # mentions
  • Orchestrators - Revamped planning capabilities with API access via "/planner" endpoint
  • Models - Mystica/Mystica 1.5 intelligence upgrades + GLM 4.6 with fast inference
  • Agent Tools - Basic Auth support for legacy integrations
