You don't need a cloud API to get a great AI coding assistant. The best open-source code models in 2026 run locally via Ollama, produce surprisingly good completions, and keep your proprietary code off someone else's servers. If you're looking to build your own home AI server, check out How to Build a Home AI Server in 2026: The Complete Guide.

Here's the definitive guide to local coding LLMs — what to run, what VRAM you need, and how to set it up with your IDE.

Why Run Coding LLMs Locally?

  • Privacy — Your code never leaves your machine. No telemetry, no training on your data.
  • Speed — No network latency. Completions feel instant on decent hardware.
  • Free — No API bills. Run as much as you want, forever.
  • Offline — Works on planes, in coffee shops, anywhere without internet.
  • Customizable — Fine-tune on your codebase, adjust system prompts, control everything.

Quick Start


# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Pull the best coding model for your VRAM
ollama pull qwen2.5-coder:14b    # 16GB VRAM
ollama pull qwen2.5-coder:32b    # 24GB+ VRAM
ollama pull qwen2.5-coder:7b     # 8GB VRAM

Top Coding Models by VRAM

🏆 Qwen 2.5 Coder — The King of Local Code

The Qwen 2.5 Coder family dominates local coding benchmarks in 2026. Available in 7B, 14B, and 32B variants, there's a size for every GPU. If you're curious about the different quantization methods mentioned, What is Quantization? A Practical Guide for Local LLMs (2026) provides a detailed explanation.

Variant Best Quant VRAM HumanEval Speed Use When
32B Q4_K_M 22GB 92.7% ~15 tok/s You have 24GB+ VRAM
14B Q5_K_M 12.9GB 87.2% ~25 tok/s You have 16GB VRAM
7B Q8_0 10GB 83.5% ~40 tok/s You have 8-12GB VRAM

ollama pull qwen2.5-coder:32b    # Best quality
ollama pull qwen2.5-coder:14b    # Best balance
ollama pull qwen2.5-coder:7b     # Best speed

Why it wins: Highest HumanEval scores of any open-source model at each size class. Excellent at Python, JavaScript, TypeScript, Rust, Go, and 30+ other languages.


💡 DeepSeek R1 Distill — Reasoning-First Coding

Varian
--------- ----------- ------ ---------- -------
14B Q5_K_M 12.9GB Complex logic ~20 tok/s
32B Q4_K_M 22GB Architecture ~12 tok/s
70B Q4_K_M 42GB Everything ~7 tok/s

DeepSeek R1 isn't specifically a code model, but its chain-of-thought reasoning makes it exceptional for:

  • Debugging complex logic
  • Designing system architecture
  • Explaining unfamiliar codebases
  • Writing algorithms from specifications

ollama pull deepseek-r1:14b

Best for: When you need the model to *think* about the problem, not just autocomplete.


⚡ Phi-4 14B — Microsoft's Efficient Coder

Spec Value
Parameters 14B
Best Quant Q5_K_M (12.9GB)
Context Window 128K
License MIT
Speed ~25 tok/s

Phi-4 matches Qwen 2.5 Coder 14B in code quality but offers a 128K context window — 4x larger. This means you can feed entire files, multiple related files, or long specifications into a single prompt.


ollama pull phi4:14b

Best for: Working with large codebases where you need to reference multiple files at once.


🚀 CodeLlama 34B — Meta's Battle-Tested Workhorse

Spec Value
Parameters 34B
Best Quant Q4_K_M (22GB)
Context Window 16K
License Llama 2 Community
Speed ~12 tok/s

CodeLlama was one of the first great open-source code models and remains solid for general-purpose coding. It's been extensively tested and has a massive community of fine-tunes and integrations.


ollama pull codellama:34b

Best for: Stable, well-tested code generation with wide language support.


🎯 StarCoder2 15B — Purpose-Built for Code

Spec Value
Parameters 15B
Best Quant Q5_K_M (13.7GB)
Context Window 16K
License BigCode OpenRAIL-M
Speed ~22 tok/s

Trained on The Stack v2 — one of the largest code datasets ever assembled. StarCoder2 excels at code completion and infilling (predicting code between two existing blocks), making it ideal for IDE integration.


ollama pull starcoder2:15b

Best for: Pure code completion and infilling tasks.


🐬 Dolphin Coder 7B — Uncensored Coding

Spec Value
Parameters 7B
Best Quant Q8_0 (10GB) or FP16 (14GB)
Context Window 33K
License Apache 2.0
Speed ~40 tok/s

Dolphin removes safety filters that sometimes interfere with legitimate code generation — like writing security testing tools, reverse engineering code, or generating code that handles sensitive topics.


ollama pull dolphin3:8b

Best for: When safety filters get in the way of legitimate coding work.


Setting Up Your IDE

The most popular way to use local LLMs for coding:

1. Install Continue.dev extension in VS Code

2. Configure to use your local Ollama:


{
  "models": [{
    "title": "Qwen Coder",
    "provider": "ollama",
    "model": "qwen2.5-coder:14b"
  }],
  "tabAutocompleteModel": {
    "title": "Qwen Coder Fast",
    "provider": "ollama",
    "model": "qwen2.5-coder:7b"
  }
}

Pro tip: Use a smaller model (7B) for tab autocomplete (needs speed) and a larger model (14B/32B) for chat/explain/refactor tasks (needs quality).

Cursor (with local models)

Cursor supports OpenAI-compatible APIs. Point it at Ollama:


# Ollama exposes an OpenAI-compatible API by default
# Use http://localhost:11434/v1 as the API endpoint

Neovim + Avante.nvim

For Neovim users, Avante.nvim provides Cursor-like AI features with local model support.


8GB VRAM (~$200 GPU)


ollama pull qwen2.5-coder:7b     # Chat/refactor
# Use the same model for autocomplete

One model does everything. Surprisingly capable.

16GB VRAM (~$600 used RTX 3090 equivalent)


ollama pull qwen2.5-coder:14b    # Chat/refactor (quality)
ollama pull qwen2.5-coder:7b     # Tab autocomplete (speed)
ollama pull deepseek-r1:14b       # Complex reasoning

The sweet spot. Three specialized models for different tasks.

24GB VRAM (RTX 3090/4090)


ollama pull qwen2.5-coder:32b    # Best code quality available
ollama pull qwen2.5-coder:7b     # Fast autocomplete
ollama pull deepseek-r1:14b       # Reasoning/debugging
ollama pull phi4:14b              # Long context (128K)

Near-cloud-API quality. The 32B Qwen Coder at Q4_K_M is genuinely impressive.

48GB+ VRAM (Mac Studio or dual GPU)


ollama pull qwen2.5-coder:32b    # Primary (Q8_0 for best quality)
ollama pull deepseek-r1:70b       # Maximum reasoning
ollama pull llama3.3:70b          # General purpose

Overkill for most. But if you have it, use it.


Benchmarks: Local vs Cloud

How do local coding models compare to cloud APIs?

Model HumanEval MBPP Cost/month
GPT-4o (cloud) 90.2% 87.8% $20-200
Claude Sonnet 4 (cloud) 93.7% 91.4% $20-100
Qwen 2.5 Coder 32B (local) 92.7% 89.1% $0
Qwen 2.5 Coder 14B (local) 87.2% 84.6% $0
DeepSeek R1 14B (local) 82.1% 79.3% $0
GitHub Copilot (cloud) ~85% ~82% $10-19

Key insight: Qwen 2.5 Coder 32B is within striking distance of GPT-4o on code benchmarks — and it's completely free to run locally. The gap has never been smaller.

Conclusion

Local coding LLMs in 2026 are genuinely good enough for professional development work. Qwen 2.5 Coder 32B on a 24GB GPU matches cloud API quality for most coding tasks, and the 14B variant on 16GB is remarkably capable.

The setup takes 5 minutes: install Ollama, pull a model, connect your IDE. Your code stays private, your API bill stays at zero, and you can code anywhere — even offline.

Start with ollama pull qwen2.5-coder:14b and see for yourself.
