OpenEuroLLM-Czech-vLLM-GGUF

OpenEuroLLM-Czech vLLM GGUF

This repository is a deployment-focused package for serving the Czech-flavored OpenEuroLLM-Czech experience with vLLM.

It uses a vLLM-compatible split Gemma 3 GGUF layout:

• gemma-3-12b-it-Q4_K_M.gguf: language model weights
• mmproj-model-f16.gguf: vision encoder and projector weights

The Czech behavior is provided by the default system prompt in czech-system-prompt.txt, adapted from the original Ollama package jobautomation/OpenEuroLLM-Czech.

Important Notes

• This is not a separately fine-tuned Czech checkpoint.
• The underlying weights are Gemma 3 12B GGUF weights packaged for vLLM deployment.
• To reproduce the Czech assistant behavior, send the system prompt from czech-system-prompt.txt with your requests.

Recommended Deployment

The safest path is to download the repository locally first so vLLM can resolve the sidecar mmproj file in the same directory.

hf download vishinvents/OpenEuroLLM-Czech-vLLM-GGUF --local-dir ./OpenEuroLLM-Czech-vLLM-GGUF

Then serve the local GGUF file:

vllm serve ./OpenEuroLLM-Czech-vLLM-GGUF/gemma-3-12b-it-Q4_K_M.gguf \
  --tokenizer unsloth/gemma-3-12b-it \
  --served-model-name OpenEuroLLM-Czech

If you are using images, keep mmproj-model-f16.gguf in the same directory as the main GGUF.

Using the Czech Prompt

Send the contents of czech-system-prompt.txt as the system message in your chat requests.
