ModelVRAM — Know if an LLM fits your GPU before you download it

About ModelVRAM

Free, in-browser VRAM calculators for running LLMs and image models locally: per-model memory (weights + KV cache), llama.cpp --n-cpu-moe offload planner for MoE models, Qwen-Image 2.1 VRAM calculator, "Can I run X on Y" pages and an open CC BY 4.0 dataset. No signup, no ads.

Who it is for
People running LLMs and image models locally (llama.cpp, Ollama, ComfyUI) who need a model, quant and context that fit their GPU.
Problem it solves
Model downloads are tens of gigabytes, and it is hard to tell in advance whether weights plus KV cache will fit in VRAM, or how much of a MoE model to offload to the CPU.
The solution
Free in-browser calculators estimate per-model memory (weights + KV cache), plan llama.cpp --n-cpu-moe offload for MoE models, estimate Qwen-Image 2.1 VRAM, and answer Can I run X on Y questions before you download anything.
What makes it unique
No signup, no ads, runs entirely in the browser, and the underlying model dataset is open under CC BY 4.0 with source code on GitHub.
