DeepSeek VisionPlus: Text goes to DeepSeek, images automatically routed to free vision model pools

When using DeepSeek Harness (DSH), there is an unavoidable limitation: DeepSeek's official models are text-only and cannot process images. When screenshots, charts, or interface photos appear in a message, one must either manually transcribe the content or switch the entire conversation to another multimodal model, resulting in a break in context. DeepSeek VisionPlus takes a different approach: text requests continue to be handled by the DeepSeek official API, while images are automatically routed to a pool of free visual models, with the understanding results returned to the same conversation. DSH's philosophy is that "everything is a plugin," and this capability is implemented as a plugin. Below is an introduction to its features, installation, and daily usage.
