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.
Features
