What's New in Version 0.674.0

Released on March 16, 2026

This release brings enhanced agentic capabilities to Mystica models, a powerful new MagicWand API for training data generation, native fine-tuning support for specialised use cases, and seamless Twilio mobile phone integration for voice agents! 🚀

🤖 Enhanced Mystica Models and Tool Calling capability​

Improved Agentic Skills for Mystica Family Models​

The Mystica family of models has received significant upgrades to their tool calling capabilities and overall agentic skills, making them more capable and reliable for complex task execution.

Key Improvements:

  • Enhanced Tool Selection - More accurate identification of the right tools for specific tasks
  • Improved Parameter Extraction - Better understanding and extraction of parameters from natural language context
  • Robust Error Handling - More graceful recovery when tool calls fail or return unexpected results
  • Multi-Step Reasoning - Superior ability to chain multiple tool calls together for complex workflows
  • JSON Output Precision - Enhanced reliability when generating structured JSON outputs from tool results

These improvements make Mystica models even more effective for building sophisticated agentic applications that require precise tool interactions.

🪄 MagicWand API Endpoint​

Transform Conversations into Training Data​

We're excited to introduce MagicWand, a revolutionary new AI API endpoint that enables seamless conversion of agent conversations into curated training datasets.

Key Capabilities:

  • Conversation to Dataset - Automatically convert existing agent conversations into structured training data
  • SFT & DPO Support - Generate data formatted for both Supervised Fine-Tuning (SFT) and Direct Preference Optimisation (DPO)
  • Curated Quality - Intelligent filtering and quality assurance to ensure high-value training examples
  • Seamless Integration - Simple API interface that works with existing conversation histories
  • Customisable Extraction - Configure what types of interactions to extract based on your training goals

Availability: MagicWand is available exclusively for Business and Enterprise subscriptions.

This powerful capability allows organisations to continuously improve their models by leveraging real-world agent interactions as training material, creating a virtuous cycle of improvement.

🔧 Tool Calling Native Fine-Tuning Capabilities​

Specialised SFT & DPO for Tool Calling and JSON Outputs​

We're introducing native tool calling fine-tuning capabilities specifically designed to enhance agent performance on critical enterprise use cases.

New Capabilities:

  • Tool Calling Optimisation - Fine-tune models specifically for improved function calling accuracy and reliability
  • JSON Output Fine-Tuning - Specialised training for consistent, schema-compliant JSON generation
  • Custom Model Variants - Create specialised versions of models optimised for your specific use cases

These fine-tuning capabilities enable organisations to build highly specialised agents that excel at specific tasks, from precise API integrations to reliable structured data extraction.

📞 Twilio Mobile Phone Integration​

Connect Any Phone Number to ToothFairyAI Agents​

We've introduced native Twilio integration with mobile phones, enabling businesses to connect their existing phone numbers directly to ToothFairyAI voice agents through a seamless self-service setup.

Key Features:
