LLM VRAM calculator
A model download is only part of its memory cost. Choose a concrete build and conversation length to estimate weights, KV cache, runtime overhead and compute buffers. No hardware profile or download is required.

The KV cache is calculated from the stored architecture; runtime overhead and compute buffers are still estimates. These are working-memory estimates, not a VRAM-capacity guarantee. Your display and operating system need headroom. On Apple Silicon, CPU and GPU share the same memory pool.

How to use the number
Compare quantizations of the same build at the same context. A lower-bit build often uses less memory but can change output quality. Longer context grows the KV cache for autoregressive models. Encoder-only models can have different cache behavior. This calculator describes inference, not training or fine-tuning.
The engine estimates one loaded model. Parallel requests, vision inputs, other applications and runtime settings can raise actual use. A fit does not predict tokens per second.
