VRAM Calculator
Estimate AI tokens, costs, and usage with VRAM Calculator on AboveTool. Free browser calculator for developers and teams — no data sent to servers.
VRAM Calculator
estimates GPU VRAM for inference or training from parameters, precision, and context
Illustrative planning math only — vendor prices and tokenizers change. Nothing is uploaded to a server unless a mode explicitly calls a public API (none do here).
About VRAM Calculator
VRAM Calculator is used to calculate how much GPU VRAM is required to load and run an LLM at a specific parameter size, quantization level, and batch size. It works by: it computes VRAM usage as: model parameters × bytes per parameter (based on quantization) + KV cache size + activation memory overhead. INT4 quantization (4-bit) reduces VRAM by ~75% vs FP16 with modest quality loss — it is often the best trade-off for fitting large models on consumer or mid-range GPUs. VRAM Calculator runs free in your browser at abovetool.com — no signup required.
