I tested the model using llama server and the response is always in HTML. How do i switch to Markdown or Plain Text output?

./llama-server \
  -m /apps/models/chandra-gguf/chandra-Q8_0.gguf \
  --mmproj /apps/models/chandra-gguf/chandra-mmproj-f16.gguf \
  --device none \
  -ngl 0 \
  --no-mmproj-offload \
  -t 40 \
  -tb 40 \
  --numa distribute \
  -c 8192 \
  -b 1024 \
  -ub 512 \
  -np 1 \
  --mmap \
  --mlock \
  --no-warmup \
  --log-timestamps \
  --verbose \
  --host 0.0.0.0 \
  --port 9000

@lokit2356
In a way like that, Chandra always provides the output in HTML format, such as HTML markdowns, OCR, and JSON, for more accurate reconstruction of the input document page.

Thanks. I just discovered that there is a Markdown parser in their output module of chandra's official Python package. This could imply that the model only outputs HTML, and the Markdown is simply a parsed representation of that HTML.
