Quick note about the linked project: it’s an experimental, unofficial pure-Rust inference implementation of DeepSeek-OCR-2 using Burn (v0.20.1). It loads the HF safetensors weights and supports Vulkan (wgpu) and NdArray backends. This PR only adds the README link; no code is added to this repo. Happy to tweak the wording/format if you prefer.

Cool stuff. Thanks!

Like you're doing interesting things with store adapter in https://github.com/huahuadeliaoliao/DeepSeek-OCR-2-burn/blob/main/src/store_adapters.rs

Feedback or PR is welcome in Burn. I worked on burn-store.
