📄 Description

Description

(discussion https://github.com/open-webui/open-webui/discussions/18446)

Currently, it defaults to "pipeline", which has substantially worse performance. It attempts to support using the vlm backend, but the value is not supported. MinerU logs this:

Exception: vlm-vllm-engine backend is not supported in async mode, please use vlm-vllm-async-engine backend

Passing the backend parameter vlm-vllm-async-engine works as expected and produces more accurate markdown files.

Fixed

Change the backend parameter passed to MinerU from vlm-vllm-engine to vlm-vllm-async-engine
