The Best LOCAL Agentic Coding Workflow (Complete Guide)
TL;DR
This tutorial demonstrates how to set up a complete local agentic coding workflow using free tools, selecting appropriately-sized Qwen models based on your hardware's VRAM constraints to eliminate cloud AI subscription costs while maintaining full coding capabilities offline.
💻 Hardware Requirements & VRAM Constraints 3 insights
VRAM dictates maximum model size
Your graphics card's VRAM (Windows) or unified memory (Mac) determines which models run efficiently, with 8GB fitting 7B parameters, 12-16GB fitting 14B, 24GB fitting 32B, and 64GB+ fitting 70B models.
Memory overflow kills performance
Models must fit entirely within VRAM because overflowing into system RAM or disk storage reduces performance by roughly 100x, making agentic coding impractical.
Mac capacity vs Windows speed tradeoff
Mac M-series allows larger models using 75-80% of unified system RAM, while Windows dedicated GPUs provide faster token generation due to superior memory bandwidth despite typically smaller VRAM capacities.
🤖 Model Selection Strategy 3 insights
Dual model setup for different tasks
Deploy Qwen 2.5 Coder 1.5B for fast autocomplete on any hardware, paired with a larger model for chat and agentic coding based on available VRAM.
Qwen models matched to hardware tiers
Use Qwen 2.5 Coder 7B for 8GB VRAM/16GB Mac, Qwen 3 Coder 14B/30B for 12-24GB VRAM, and Qwen 3 Coder Next for 64GB+ systems, with 1.5B models as CPU-only fallbacks.
Tool use capability is mandatory
The primary chat model must explicitly support 'tool use' to execute bash commands and file operations required for agentic coding, not just generate text responses.
⚙️ Software Configuration 3 insights
LM Studio as the local model hub
Download and serve models through LM Studio, which provides a graphical interface for Hugging Face models and creates a local API server for coding tool integration.
VS Code native local integration
Visual Studio Code now includes built-in features specifically designed for local model integration, making it the preferred editor for connecting to LM Studio's server.
Zero-cost offline operation
Local execution eliminates subscription fees for cloud AI services like Cursor or Claude Code while enabling full agentic coding capabilities without internet connectivity.
Bottom Line
Select Qwen models that fit entirely within your available VRAM (using 75-80% of unified memory on Mac or full GPU VRAM on Windows), configure them through LM Studio with tool-use enabled, and connect to VS Code to achieve free, fully offline agentic coding.
