# Apertus EstLLM 8B 0326 Instruct

`Llama-3.1-EstLLM-8B-Instruct-0326` is obtained by applying the chat-vector merge approach
to [tartuNLP/Apertus-EstLLM-8B-Instruct-1125](https://huggingface.co/tartuNLP/Apertus-EstLLM-8B-Instruct-1125).

## Use with transformers

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "tartuNLP/Apertus-EstLLM-8B-Instruct-0326"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    dtype="auto",
    device_map="auto"
)

# to use on apple silicon, load the following way
# model = AutoModelForCausalLM.from_pretrained(
#     model_name,
#     dtype=torch.float16,
#     device_map="mps",
# )

tokenizer = AutoTokenizer.from_pretrained(model_name)

messages = [
    {"role": "user", "content": "Kas sa räägid eesti keelt?"}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

model_inputs = tokenizer(text, return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=128,
    do_sample=True,
    temperature=0.4,
    # specify eos token to stop at the end of the assistant response
    eos_token_id=tokenizer.eos_token_id,
)

# generated_ids include the input tokens as well, so we only decode new tokens
response = tokenizer.decode(
    generated_ids[0][model_inputs["input_ids"].shape[1]:],
    skip_special_tokens=True,
)

print(response)
```

## Evaluation

## Logits-based

Scores for logits-based evaluation benchmarks are available on the [EuroEval](https://euroeval.com/leaderboards/Monolingual/estonian/) leaderboard.

## Generative

Every benchmark in this category is treated as a *generative* problem, and thus the evaluation is performed on the model responses obtained with 0 temperature (not logits).
The top scores are higlighted with **bold**. Second best scores are highlighted with **_italic bold_**. Rows are sorted in descending order based on the number of parameters of models (not scores).
The test set is used for evaluation of each dataset unless noted otherwise.

Note that _all models are evaluated with the same prompt template_ for comparability, meaning that the scores do not necessarily represent each model's best possible
performance. This is especially the case for `deepseek-ai/DeepSeek-V3-0324` on some of the benchmarks.

Only models of comparable size are evaluated on benchmarks in English.
