> Live prices and model-fit estimates for the GPUs and desktop boxes used to run AI models locally. Prices are tracked on eBay, with Amazon links on every product page, and every price carries the time it was observed.

Pages are plain HTML and carry the numbers an assistant needs: memory, bandwidth, the current lowest price with vendor and timestamp, and which models fit at which quantisation with estimated decode and prefill tokens per second. Estimates follow the formulas on the methodology page and are labelled as estimates. Product URLs are stable: /gpus/{slug} and /boxes/{slug}. Each product also has /ebay with every active listing that passes the filters.
