This model has been superseded by a newer version (v1.5) here
🚨 HOWEVER, CONSIDER USING Krikri 8B Instruct, OUR NEWEST INSTRUCT MODEL WHICH OUTPERFORMS MELTEMI BY +34.8% ON GREEK IFEval! 🚨
Meltemi Instruct Large Language Model for the Greek language
We present Meltemi-7B-Instruct-v1 Large Language Model (LLM), an instruct fine-tuned version of Meltemi-7B-v1.
Model Information
- Vocabulary extension of the Mistral-7b tokenizer with Greek tokens
- 8192 context length
- Fine-tuned with 100k Greek machine translated instructions extracted from:
- Open-Platypus (only subsets with permissive licenses)
- Evol-Instruct
- Capybara
- A hand-crafted Greek dataset with multi-turn examples steering the instruction-tuned model towards safe and harmless responses
- Our SFT procedure is based on the Hugging Face finetuning recipes
Instruction format
The prompt format is the same as the Zephyr format and can be utilized through the tokenizer's chat template functionality as follows:
from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda" # the device to load the model onto
model = AutoModelForCausalLM.from_pretrained("ilsp/Meltemi-7B-Instruct-v1")
tokenizer = AutoTokenizer.from_pretrained("ilsp/Meltemi-7B-Instruct-v1")
model.to(device)

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. The suite is integrated with lm-eval-harness.
Our evaluation suite includes:
- Four machine-translated versions (ARC Greek, Truthful QA Greek, HellaSwag Greek, MMLU Greek) of established English benchmarks for language understanding and reasoning (ARC Challenge, Truthful QA, Hellaswag, MMLU).
- An existing benchmark for question answering in Greek (Belebele)
- A novel benchmark created by the ILSP team for medical question answering based on the medical exams of DOATAP (Medical MCQA).
Our evaluation for Meltemi-7b is performed in a few-shot setting, consistent with the settings in the Open LLM leaderboard. We can see that our training enhances performance across all Greek test sets by a +14.9% average improvement. 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 | 41.0% | 63.6% | 61.6% | 43.2% | 52.1% | 47% | 51.4% |
Ethical Considerations
This model has not been aligned with human preferences, and therefore might generate misleading, harmful, and toxic content.
