🐛 Describe the bug

Running .gguf files without .gguf extension does not work... renaming these files with .gguf extension and running without any flags (just using "vllm serve granite-code:latest.gguf") works.

Expected behaviour is that we don't require .gguf extension to run .gguf file.

$ vllm serve ~/.local/share/ramalama/models/ollama/granite-code:latest --quantization gguf --load-format gguf

Thanks for reporting! This would be a bit tricky to achieve cleanly since we need to pipe down the information to these places for fetching the config and tokenizer from the file

	model = Path(model).parent

@mgoin I think we can use GGUF magic number to achieve this easily:
