Privacy

Catalogue lookup still runs in your browser. When the site’s ask endpoint is available, submitting a question sends the question and the retrieved catalogue records through /api/ask on Cloudflare to a local model in Dongli’s workshop. The endpoint caps input length, applies a per-IP rate limit, and answers only from those records; it does not promise stock, interchange, OEM authorisation or price. If the endpoint is unreachable, the page falls back to catalogue cards. The inquiry form only tries to open an email draft addressed to Wales@oildrillingpump.com.

The optional secondary on-device model is Qwen2.5-0.5B-Instruct (Apache 2.0), run on your device through WebLLM. Only after you click “Load on-device model” does the browser download about 276 MB of weights from the public Hugging Face / jsDelivr addresses, and cache them locally. It is used only if the workshop model is unavailable and you have already loaded it. Dongli does not collect those weights. If WebGPU is missing, nothing is downloaded.

This site does not expose the workshop model’s raw interface to the public internet.

This local preview does not include analytics or advertising tracking. If a published version later adds analytics, this page will be updated.
