Florents Tselai has released a HuggingFace repository containing the 'llamafile' and 'gguf' file formats for Meltemi 7B Instruct v1.5, the first Greek Large Language Model developed by Athena Research & Innovation Center. The 'llamafile' combines a web server API, CLI, and chat application in one executable, while the 'gguf' format works with llama.cpp.
