Astral - Gemma 3 with Tool Calling

A customized version of Gemma 3 with native tool calling support, optimized for n8n and workflow automation platforms.

Overview

Astral extends Google’s Gemma 3 model with built-in tool calling capabilities, making it seamlessly compatible with automation platforms like n8n that require structured function execution.

Why This Exists

Ollama’s base Gemma 3 implementation doesn’t include a tool-calling template out of the box. When attempting to integrate it with n8n’s AI Agent nodes or similar workflow tools, you’ll encounter compatibility issues due to the missing function calling interface.

Astral solves this by adding a properly formatted tool calling layer that enables:

  • Native function execution - Call external tools and APIs directly from the model
  • Workflow integration - Seamless compatibility with n8n, LangChain, and other automation frameworks
  • Structured outputs - Reliable JSON responses for programmatic consumption

Use Cases

  • Building AI agents in n8n workflows
  • Automating complex multi-step processes
  • Creating chatbots with access to external data sources
  • Integrating LLMs into existing business automation pipelines
