Learn how to build a blazing fast and fully private AI coding assistant using Qwen3, Ollama, and Continue.dev to enhance your development workflow.

Introduction

In the rapidly evolving landscape of software development, efficiency and privacy are paramount. Building a local AI coding assistant leverages advancements in artificial intelligence to streamline your workflow, enhance productivity, and maintain complete control over your data. This guide explores integrating Qwen3, Ollama, and Continue.dev to create a robust AI coding assistant tailored to your development needs.

Why Choose a Local AI Coding Assistant?

Opting for a local AI coding assistant offers numerous benefits:

Privacy and Security: Keep your codebase private without relying on external APIs.
Speed and Efficiency: Experience faster response times by running models locally.
Customization: Tailor the assistant to understand your specific codebase and development practices.
Cost-Effective: Avoid recurring subscription fees associated with cloud-based AI services.

Key Components for Building Your AI Coding Assistant

Qwen3: The Performance Powerhouse

Qwen3 stands out with its 30b-a3b variant, offering a balance between performance and resource efficiency. Utilizing distillation and Mixture-of-Experts (MoE) techniques, Qwen3 delivers swift inference times, making it ideal for real-time coding assistance. Despite its extensive capabilities, it operates smoothly on standard laptops, ensuring accessibility without compromising power.

Ollama: Local Model Hosting

Ollama facilitates the local hosting of large language models (LLMs), enabling you to run sophisticated AI models like Qwen3 without the need for cloud-based services. This ensures that your development environment remains fully private and under your control.

Continue.dev: Seamless Integration with VS Code

Continue.dev offers a seamless experience by integrating your local AI models with Visual Studio Code. This extension transforms VS Code into a smart development environment, leveraging the power of your AI coding assistant to provide context-aware suggestions, autocompletions, and edits.

Step-by-Step Guide to Setting Up Your AI Coding Assistant

Step 1: Install Ollama

Begin by installing Ollama, which will host your AI models locally.

For Mac:

brew install ollama

For Windows:
Download the installer from ollama.com/download and follow the installation prompts.

Step 2: Pull Qwen3 and Embedding Model

Once Ollama is installed, pull the necessary models.

Open your terminal or PowerShell and execute:

ollama pull qwen3:30b-a3b
ollama pull nomic-embed-text

Qwen3-30b-a3b: Serves as the main AI brain handling chat, autocomplete, edits, and more.
Nomic-embed-text: Enhances the AI’s understanding of your entire codebase, ensuring context-aware assistance.

Step 3: Install Continue.dev Extension in VS Code

Enhance your VS Code with the Continue.dev extension:

Open Visual Studio Code.
Navigate to the Extensions panel by clicking the 🔍 icon on the left sidebar.
Search for “Continue” and click Install.

Step 4: Configure Continue.dev to Use Qwen3

Customize the extension to utilize your locally hosted Qwen3 model:

In VS Code, go to the Continue tab (🧠 icon).
Click the gear ⚙️ icon and select Open Config.
Replace the default configuration with the following YAML configuration:

name: Local Assistant
version: 1.0.0
schema: v1
models:
  - name: Qwen3-30b
    provider: ollama
    model: qwen3:30b-a3b
    roles:
      - chat
      - edit
      - autocomplete
      - apply
      - summarize
  - name: embeddingsProvider
    provider: ollama
    model: nomic-embed-text
    roles:
      - embed
context:
  - provider: code
  - provider: docs
  - provider: diff
  - provider: terminal
  - provider: problems
  - provider: folder
  - provider: codebase

Configuration Breakdown:

Models: Defines the AI models used by the assistant.
Context: Specifies the data sources the assistant can access, such as the current file, documentation, Git changes, terminal output, and the entire codebase.

Step 5: Finalize the Setup

With the configuration in place, your local AI coding assistant is ready to use. Enjoy a private, fast, and powerful development experience directly within VS Code.

Enhancing Your Workflow with CodeAI

Integrating your AI coding assistant with CodeAI can further revolutionize your frontend development. CodeAI’s Agentic Context Engine (ACE) understands your specific codebase, enabling the AI to generate production-grade code based on simple descriptions. This synergy allows teams to build user interfaces up to ten times faster while maintaining high standards for code quality and design consistency.

Benefits of Combining Qwen3, Ollama, Continue.dev, and CodeAI:

Streamlined Workflows: Automate repetitive coding tasks and focus on creative problem-solving.
Collaborative Efficiency: Empower both technical and non-technical team members to contribute effectively.
Consistent Code Quality: Ensure uniformity across your codebase with AI-assisted development.

Conclusion

Building a local AI coding assistant using Qwen3, Ollama, and Continue.dev offers a transformative approach to software development. By maintaining complete control over your data, enhancing development speed, and integrating seamlessly with tools like CodeAI, you can elevate your team’s productivity and maintain high standards in your projects. Embrace the future of AI-driven development and empower your workflow with a bespoke AI coding assistant.
