DeepSeek-OCR is a separate document-recognition model, so full DeepSeek-R1 hardware requirements do not apply to it. A GPU test needs the exact version, page-processing mode and expected output. Start with one authorised image before expanding input size or batching.

The useful result is a documented recognition profile, not a claim that one successful page validates every document in an archive.

## Use the correct model documentation

The official DeepSeek-OCR model card includes implementation examples, while the authors' repository provides launch instructions and processing modes. Preserve the chosen revision and software versions rather than combining steps from unrelated guides.

Confirm the supported execution path before downloading a large collection. Record the input processor and any page preparation settings. The same source image can create a different workload under a different preprocessing configuration.

## Fix the page-processing conditions

| Condition | Evidence to preserve |
| --- | --- |
| Source page | Authorised sample identifier |
| Image preparation | Dimensions and processing mode |
| Model artifact | Revision and format |
| Execution | Engine and device |
| Expected result | Text or fields checked |
| Saved output | Location and completion status |

These fields make a comparison reproducible. They do not establish universal minimum VRAM or a throughput promise for a particular GPU.

## Check the result element by element

Prepare pages containing ordinary text, numbers, layout changes and other features relevant to the intended dataset. Define correct output for a subset before testing. Record omissions, invented characters and incorrect ordering rather than relying only on visual plausibility.

If the task requires document structure, state what must be preserved. A readable text fragment may still be unsuitable when table relationships or field values are wrong. Compare settings on the same pages before treating lower memory use as an improvement.

## Observe RAM, VRAM and the complete path

Measure file preparation, model execution and output saving separately, plus total duration. CPU memory and temporary disk use can matter before GPU inference starts. Keep system RAM distinct from device-local memory.

Begin with one page and increase one factor at a time. Test recovery after an unsuccessful request and confirm temporary resources are accounted for. Successful loading does not establish sustained archive processing or arbitrary parallelism.

A bounded recognition pilot can identify useful hardware work while leaving untested formats, data restrictions and scaling questions explicit.
