Python:

model = 'deepseek-ocr:3b-bf16'
image = sys.argv[1] if len(sys.argv) > 1 else "puppy.jpg"

        'content': '\n<|grounding|>Describe this image.',
        'images': [image]
    }],
    stream=True
)

for r in response:
  print(r['message']['content'], end='')
print("")

The model is completely unstable. It periodically returns complete nonsense on the same file...

The model is very sensitive to variations of input. Recommended prompts can be found here.

@TkachenkoAV I saw the request api just works when we call to chat endpoint. If we call to /generate endpoint does not work. Simple app to consume the model:
