| # 🚨 **CONSIDER USING [Krikri 8B Instruct](https://huggingface.co/ilsp/Llama-Krikri-8B-Instruct), OUR NEWEST INSTRUCT MODEL WHICH OUTPERFORMS MELTEMI BY +34.8% ON [GREEK IFEval](https://huggingface.co/datasets/ilsp/ifeval_greek)!** 🚨 | |
| # Meltemi Instruct Large Language Model for the Greek language | |
| We present Meltemi 7B Instruct v1.5 Large Language Model (LLM), a new and improved instruction fine-tuned version of [Meltemi 7B v1.5](https://huggingface.co/ilsp/Meltemi-7B-v1.5). | |
|  | |
| # Model Information | |
| - Vocabulary extension of the Mistral 7b tokenizer with Greek tokens for lower costs and faster inference (**1.52** vs. 6.80 tokens/word for Greek) | |
| - 8192 context length | |
| - Fine-tuning has been done with the [Odds Ratio Preference Optimization (ORPO)](https://arxiv.org/abs/2403.07691) algorithm using 97k preference data: | |
| * 89,730 Greek preference data which are mostly translated versions of high-quality datasets on Hugging Face | |
| * 7,342 English preference data | |
| - Our alignment procedure is based on the [TRL - Transformer Reinforcement Learning](https://huggingface.co/docs/trl/index) library and partially on the [Hugging Face finetuning recipes](https://github.com/huggingface/alignment-handbook) | |
| # Instruction format | |
| The prompt format is the same as the [Zephyr](https://huggingface.co/HuggingFaceH4/zephyr-7b-beta) format and can be | |
| utilized through the tokenizer's [chat template](https://huggingface.co/docs/transformers/main/chat_templating) functionality as follows: | |
| ```python | |
| from transformers import AutoModelForCausalLM, AutoTokenizer | |
| device = "cuda" # the device to load the model onto | |
| model = AutoModelForCausalLM.from_pretrained("ilsp/Meltemi-7B-Instruct-v1.5") | |
| tokenizer = AutoTokenizer.from_pretrained("ilsp/Meltemi-7B-Instruct-v1.5") | |
| model.to(device) | |
| messages = [ | |

| Please make sure that the BOS token is always included in the tokenized prompts. This might not be the default setting in all evaluation or fine-tuning frameworks. | |
| # Evaluation | |
| The evaluation suite we created includes 6 test sets and has been implemented based on a [fork](https://github.com/LeonVouk/lighteval) of the [lighteval](https://github.com/huggingface/lighteval) framework. | |
| Our evaluation suite includes: | |
| * Four machine-translated versions ([ARC Greek](https://huggingface.co/datasets/ilsp/arc_greek), [Truthful QA Greek](https://huggingface.co/datasets/ilsp/truthful_qa_greek), [HellaSwag Greek](https://huggingface.co/datasets/ilsp/hellaswag_greek), [MMLU Greek](https://huggingface.co/datasets/ilsp/mmlu_greek)) of established English benchmarks for language understanding and reasoning ([ARC Challenge](https://arxiv.org/abs/1803.05457), [Truthful QA](https://arxiv.org/abs/2109.07958), [Hellaswag](https://arxiv.org/abs/1905.07830), [MMLU](https://arxiv.org/abs/2009.03300)). | |
| * An existing benchmark for question answering in Greek ([Belebele](https://arxiv.org/abs/2308.16884)) | |
| * A novel benchmark created by the ILSP team for medical question answering based on the medical exams of [DOATAP](https://www.doatap.gr) ([Medical MCQA](https://huggingface.co/datasets/ilsp/medical_mcqa_greek)). | |
| Our evaluation is performed in a few-shot setting, consistent with the settings in the [Open LLM leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard). | |
| We can see that our new training and fine-tuning procedure for Meltemi 7B Instruct v1.5 enhances performance across all Greek test sets by a **+7.8%** average improvement compared to the earlier Meltemi Instruct 7B v1 model. The results for the Greek test sets are shown in the following table: | |
| | | Medical MCQA EL (15-shot) | Belebele EL (5-shot) | HellaSwag EL (10-shot) | ARC-Challenge EL (25-shot) | TruthfulQA MC2 EL (0-shot) | MMLU EL (5-shot) | **Average** | | |
| |----------------|----------------|-------------|--------------|------------------|-------------------|---------|---------| | |
| | Mistral 7B | 29.8% | 45.0% | 36.5% | 27.1% | 45.8% | 35% | **36.5%** | | |
| | Meltemi 7B Instruct v1 | 36.1% | 56.0% | 59.0% | 44.4% | 51.1% | 34.1% | **46.8%** | | |
| | Meltemi 7B Instruct v1.5 | 48.0% | 75.5% | 63.7% | 40.8% | 53.8% | 45.9% | **54.6%** | | |
