The Invisible Overhead
Most VRAM calculators only show model size at 4-bit quantization. They ignore the reality that your GPU is never 100% available for the model. Here's what actually consumes VRAM:
Operating System
Windows 11: ~2-4GB for desktop composition, DWM, and system processes
macOS: ~1.5-3GB for window server and graphics pipeline
Development Environment
VS Code / JetBrains: ~500MB-2GB depending on extensions and GPU acceleration features
Browser & Applications
Chrome/Edge: ~300-800MB per tab with hardware acceleration
Other apps: Discord, Spotify, and other GPU-accelerated software
Agent Context Growth
KV cache that expands with usage. A 10k token context can add 2-4GB of VRAM during active inference.

| DeepSeek-R1-Distill-Qwen-32B | 32B | ~20 GB | 24GB+ |
| DeepSeek-R1-Distill-Llama-70B | 70B | ~42 GB | 48GB+ |
| DeepSeek-V3 (671B Full) | 671B | ~300 GB | Multi-GPU / Cloud |
* VRAM requirements shown are for 4-bit quantization only. Actual usage varies by context size and KV cache.
Understanding Your Results
RED (Local Setup Not Viable)
Physics limit reached. Your VRAM will cause instability or OOM loops. Consider cloud GPU options for reliable inference.
YELLOW (High Risk Zone)
You're on the razor's edge. Browser tabs or IDE plugins will crash you. Close unnecessary applications before running inference.
READY (Viable)
Hardware looks good. Bookmark this page for updated boundaries as models grow. Monitor VRAM usage during long sessions.
