OPT_GaMS-1B-Chat

Model Card for OPT_GaMS-1B-Chat

We proudly present the family of GaMS (Generative Model for Slovene) models. The 1B version is based on Facebook's OPT model and is adapted for Slovene. OPT_GaMS models use the original OPT tokenizer. This is the instruction-tuned version of the model.

Acknowledgment

The model was developed within the PoVeJMo research program (Adaptive Natural Language Processing with Large Language Models), particularly within the research project titled SloLLaMai -- Open-access computationally efficient models for Slovenian. The program is funded within the Recovery and Resilience Plan by the Slovenian Research and Innovation Agency (ARIS) and NextGenerationEU. The authors also acknowledge the financial support from the Slovenian Research and Innovation Agency (research core funding No. P6-0411 -- Language Resources and Technologies for Slovene).

We thank everyone who worked on data collection and preparation, enabling us to train our model. Special thanks go to Nikola Ljubešić, Tjaša Arčon, Jaka Čibej, Simon Krek, Tomaž Erjavec and Iztok Kosem.

Intended usage

This version of the model is quite small and lacks safety tuning. Hence, using it as a general-purpose model is STRONGLY DISCOURAGED! The model might also contain certain biases. We do not recommend the usage of this model in any other language than Slovene.

The model can be efficiently tuned for specific use cases as suggested by promising results of fine-tuned models on SuperGLUE and SI-NLI benchmarks

How to get started with the model

The inference can be done using the following snippet of code:

from transformers import pipeline

model_id = ("cjvt/OPT_GaMS-1B-Chat")

pipeline = transformers.pipeline(
        "text-generation",
        model=model_id,
        device_map="auto"
    )

# Example of response generation
message = [{"role": "user", "content": "Kateri je najpomembnejši dogodek v slovenski zgodovini?"}]
response = pipeline(message, max_length=100)
print("Model's response:", response[0]["generated_text"][-1]["content"])

# Example of conversation chain
new_message = response[0]["generated_text"]
new_message.append({"role": "user", "content": "Lahko bolj podrobno opišeš ta dogodek?"})
response = pipeline(new_message, max_length=500)
print("Model's response:", response[0]["generated_text"][-1]["content"])

Training details

Training data

The model was additionally pretrained on the following Slovene, English, and Croatian-Bosnian-Serbian (CBS) corpora:

The total size of additional training data is 47.44 B tokens.

Training Procedure

The model was trained using the NeMo framework on Slovene HPC Vega, utilizing 64 A100 GPUs simultaneously. Training took approximately 16 hours. The model was trained with batch size 1024 (2 million tokens) using Adam optimizer and cosine learning rate scheduler with 1000 warmup and constant steps.

Supervised Finetuning (SFT)

The model was trained on GaMS-Instruct dataset (20.000 examples). The curated version of the dataset (7.000 examples) is publicly available. 19.050 examples were used as a training set and 950 examples were used as a validation set.

The model was LoRA tuned on 7 epochs with rank 1024. The model was trained with batch size 64 using Adam optimizer and cosine learning rate scheduler with 300 warmup steps.

Evaluation

The models were evaluated using Slovene SuperGLUE and SI-NLI tasks on SloBench. Additionally, the models were evaluated on an improved version of the Slovenian-LLM-eval introduced by Aleksa Gordić. All decoder-type models were evaluated using few-shot prompts and were not finetuned on the benchmark (except for the versions with finetuned in the name).
