You Can Use ANY Local LLM in Antigravity!
6 min read
Summary
This video tutorial demonstrates how to significantly expand your large language model (LLM) catalog in the antigraphy platform by integrating and running open-source LLMs locally using LM Studio. The presenter guides viewers through the setup process, from downloading LM Studio to configuring a custom server in antigraphy, enabling the use of models beyond the default offerings.
Key Steps and Insights
- Downloading and Installing LM Studio:
- Visit the LM Studio website, select your platform, download, and install the software.
- LM Studio provides access to many free, open-source models hosted on Hugging Face.
- Examples of downloadable models include JM 4.7 flash and Google Gemini 34B.
- Once installed, you can load your chosen model and run it locally by switching the status from off to on, effectively turning your machine into a local server hosting the model.
- Creating a Custom Model Router in Antigraphy:
- After setting up LM Studio, return to antigraphy and create a model router script (e.g.,
model_router.py). - This script is written using FastAPI and MCP frameworks to handle the server requests and model interaction.
- The video emphasizes that no expert coding skills are needed because AI tools can generate this code.
- The script includes:
- Import statements for FastAPI, HPX, MCP, and related tools.
- Configuration settings such as system prompts and temperature parameters.
- Server setup details that can be left mostly unchanged.
- The presenter offers to share this code upon request.
- Configuring MCP Server in Antigraphy:
- Navigate to MCP servers via the menu in antigraphy.
- Since the server is custom, use Manage MCP to find and configure it.
- Configuration involves editing a JSON file with server parameters.
- This JSON file and related code are available upon request from the presenter.
- Testing the Setup:
- Once the server is running, test it by sending a query (e.g., "Hello, who are you?") through the LM Studio router.
- The local model responds instantly; in the example, Gemini 3 flash replies with "Hi there, I'm Gemma."
- The presenter notes that the response speed depends on the model size and PC capability.
- The setup allows flexibility including chaining multiple models or having one model call another, enhancing antigraphy’s native model catalog.
Core Concepts and Definitions
| Term | Description |
|---|---|
| LM Studio | A downloadable application to run open-source LLMs locally on your PC, turning it into a server. |
| Antigraphy | The platform being extended with additional LLMs via custom model routing and MCP configuration. |
| MCP (Model Communication Protocol) | A protocol for server communication enabling interaction with local LLMs in antigraphy. |
| FastAPI | A Python web framework used to create the model router API for server-client communication. |
| Model Router | A custom Python script that routes requests from antigraphy to the local LLM server. |
Highlights
- No advanced coding required: AI-assisted code generation simplifies creating the model router.
- Use of free/open-source models: Enables access to a larger variety of LLMs from Hugging Face.
- Local hosting of LLMs: Avoids dependency on cloud APIs, reducing latency and potential costs.
- Customizability: Users can tweak prompts, temperature, and even chain models for complex workflows.
- PC requirements: Larger models require more capable hardware, but smaller/light models respond quickly on average PCs.
