VRAM Requirements (Q4_K_M Quantization)

Running coding models smoothly requires fitting the entire active weights into high-bandwidth VRAM or unified memory. Here is how much memory each parameter tier occupies at the standard Q4_K_M quantization:

4.5 GB
7B Dense Model
9.0 GB
14B Dense Model
19.2 GB
30B MoE (3.3B Active)
42.5 GB
70B Dense Model
Context Memory Rule: Base weight sizes assume a standard 8K context window. If you plan to ingest large files or multi-file repositories up to 32K or 128K context, add +3GB to +8GB of additional memory buffer for the KV cache.

Top 3 Ollama Coding Models for 2026

1. Best for 8GB VRAM: Qwen2.5-Coder:7B

Budget & Laptop King

Alibaba's Qwen2.5-Coder:7B remains unmatched in the sub-10GB tier. It scores above 82% on HumanEval, rivaling older 33B-parameter models in Python, TypeScript, Rust, and Go.

  • Ideal Hardware: RTX 3060, RTX 4060, Apple M1/M2/M3 (16GB RAM), or Radeon RX 7600 XT.
  • Strengths: Lightning-fast generation (~65+ tokens/sec on modern cards), exceptional FIM (Fill-in-the-Middle) code completions.

2. Best for 16GB VRAM: Qwen3-Coder:30B-A3B

MoE Efficiency Pick

The Qwen3-Coder-30B-A3B uses a sparse Mixture-of-Experts (MoE) architecture. While the model contains 30 billion total parameters for deep multi-file reasoning, it only routes 3.3 billion parameters per token during inference.

  • Ideal Hardware: RTX 4080 (16GB), RTX 5070 Ti, Apple M3/M4 Pro (24GB Unified Memory).
  • Strengths: Solves complex architectural refactoring and tricky edge cases while running at the speed of a tiny 3B model.

3. Best for 24GB+ VRAM: DeepSeek-V4-Flash

Workstation Flagship

For serious autonomous agents and repo-scale workflows, DeepSeek-V4-Flash brings multi-token prediction and advanced chain-of-thought verification. It operates on large contexts without suffering context-drift.

  • Ideal Hardware: RTX 3090, RTX 4090, RTX 5090 (24GB–32GB), or Mac Studio (64GB+).
  • Strengths: Complete test-driven development (TDD), generating comprehensive unit test suites and debugging obscure runtime crashes.

Frequently Asked Questions

Q4_K_M provides the optimum balance between memory footprint and syntactic code correctness. While Q3_K_S saves memory, it tends to introduce subtle syntax errors in whitespace-sensitive languages like Python and YAML.
Only with extreme sub-3-bit quantization (IQ2_M) and severely clipped context windows (sub-4k). In practice, a modern 30B MoE model like Qwen3-Coder:30B will generate significantly better, faster code on a single 24GB GPU than an overly compressed 70B dense model.
Yes. On macOS, Ollama uses Apple's native Metal framework and shared unified memory. On Windows and Linux, modern AMD Radeon GPUs (RDNA2/RDNA3/RDNA4) run efficiently through ROCm and Vulkan runtimes.
