We describe the development and capabilities of Meltemi 7B, the first open
Large Language Model for the Greek language. Meltemi 7B has 7 billion
parameters and is trained on a 40 billion token Greek corpus. For the
development of Meltemi 7B, we adapt Mistral, by continuous pretraining on the
Greek Corpus. Meltemi 7B contains up-to-date information up to September 2023.
Furthermore, we have translated and curated a Greek instruction corpus, which
has been used for the instruction-tuning of a chat model, named Meltemi 7B
Instruct. Special care has been given to the alignment and the removal of toxic
content for the Meltemi 7B Instruct. The developed models are evaluated on a
broad set of collected evaluation corpora, and examples of prompts and
responses are presented. Both Meltemi 7B and Meltemi 7B Instruct are available
at https://huggingface.co/ilsp under the Apache 2.0 license.
