A single-page, MIT-licensed estimator for local LLMs. Enter parameter count, precision/quantisation, context length and memory bandwidth; it shows weight memory plus KV cache and a bandwidth-bound tokens-per-second ceiling, so you can check whether a model fits a 24 GB, 32 GB or 64 GB machine before buying. Runs in the browser, no sign-up, no tracking; it is an estimate for models held fully in memory and says so.
