Model Details

NorwAI-Mistral-7B-instruct is an instruction tuned variant of NorwAI-Mistral-7B using around 9000 self-collected high-quality Norwegian instructions. It belongs to NowAI LLM family developed by NowAI research center at Norwegian University of Science and Technology (NTNU) in collaboration with Schibsted, NRK, VG and the National Library of Norway.

NorwAI LLM includes a collection of pretrained, continue pretrained and instruction tunned generative text models in 7B and 45B sizes with different archtectures. All pretrained and continue pretrained models are on the same dataset and with the same tokenizer. The instruction tuned models are optimized using high-quality Norwegian instructions collected from Norwegian native speakers. The development of these modesl is dedicated to promoting and developing the research and applications of Norwegian language models.

• Developed by: NowAI at NTNU, Schibsted and VG

• Model type: Generative text model
• Language(s) (NLP): Norwegian
• Finetuned from model: NorwAI-Mistral-7B
• Tokenizer: We expanded the Norwegian vocabulary by merging the Llama 2 tokenizer with the vocabulary from our own trained Norwegian tokenizer. The extended vocabulary size is 64000.
• Models release date: May 15, 2024 but are being continuously updated.

NowAI LLM family is based on auto-regressive language model architecture.

Uses

NowAI LLM is intended for both commercial and research use in Nordic countries. To get access to the model, please carefully read the message and complete the required information.

Bias, Risks, and Limitations

The model may have potential risks common to large language models, such as hallucination, factual inconsistency, toxicity, and bias etc.

How to use

We have two prompt templates for instruction tuning:

If we have input data, we use Prompt 1: {instruction}\n\n{inst_input}\nAnswer:

If we do not have iniput data, we use Prompt 2: {instruction}\n\nAnswer:

Let see the following example to load the model:

from transformers import AutoTokenizer, AutoModelForCausalLM

model_and_tokenizer_path = "NorwAI/NorwAI-Mistral-7B-instruct"
access_token = "<your access token>"

# import tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_and_tokenizer_path, token=access_token)
model = AutoModelForCausalLM.from_pretrained(model_and_tokenizer_path, token=access_token, device_map='balanced')

# define your own prompt
prompt = """Hvilket av de følgende alternativene er Norges nordligste punkt?\n\na) Nordkapp b) Alta c) Vardø d) Hammerfest\n
        Svar:"""

# generate response
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, 
                    min_new_tokens=50, 
                    max_new_tokens=100,
                    do_sample=True,
                    temperature=0.3)
outputs = tokenizer.decode(outputs[0], skip_special_tokens=True)

According to our test, replacing Answer with Svar can also achieve the same effect.

Training Details

Training Data

All NorwAI LLM models were (continue-)pretrained on 51.15 Billion tokens, equivalent to 30.33 Billion words, sourced from public datasets and data shared by Schibsted, NRK, and VG partners under agreement. The publicly available datasets were preprocessed to filter out texts with copyright issues, and all datasets were preprocessed to remove sensitive information.

Training Infrastructure

All models were pretrained and fine-tuned using the llm-foundary framework on the IDUN cluster in NTNU.
