Borealis Open 1B GGUF

Model Summary

NbAiLab/borealis-open-1b-gguf is a GGUF release of 1B-parameter instruction-tuned open release model in the Borealis family from the National Library of Norway (Nasjonalbiblioteket, NB).

This is the first Borealis release to incorporate data made available under the agreement between rights-holder organizations in Norway and the Norwegian government. To date, only a limited subset of the material has been used, specifically to teach the model how to generate news article titles and ingress texts. Models with the suffix -open, do not include any material from the agreement.

All Borealis released models are based on the Gemma 3 family. This GGUF repository is based on the corresponding NbAiLab/borealis-open-1b safetensors release.

Training Data

Supervised fine-tuning (SFT) uses instruction data prepared by the National Library of Norway for Norwegian-centric assistant behavior, writing, summarization, question answering, and related tasks.

The SFT dataset for this model is NbAiLab/aurora-sft-open. NbAiLab/aurora-sft-open is the open version of the SFT dataset. The only difference between NbAiLab/aurora-sft-open and NbAiLab/aurora-sft is the addition of 10k tasks derived from copyright-protected newspapers material.

Evaluation

We evaluate Borealis with NorEval, MMLU-English, and nb-gpt-bench, our own evaluation suite, which will be published and described in an upcoming paper. The full Borealis models include around 10k newspaper-derived tasks from the abovementioned agreement and show a slight performance increase in some key metrics compared with the open variants. We hope to further increase the difference by incorporating proper pre-training on the newspaper material.

Safety and Alignment

The Borealis family of models are aligned for safety using prompt baking and weighted merging of SFT and aligned models. The goal of this process is to balance model quality, usefulness, and safer behavior.

As with all generative models, outputs can still be incorrect, biased, harmful, or inappropriate. Do not use the model for safety-critical or high-stakes applications without additional evaluation and safeguards.

Prompt Baking

To align the Borealis models, we employ prompt baking, a procedure that distills the behavior induced by a system prompt directly into the model weights using bakery. Specifically, we train a LoRA adapter to minimize the KL-divergence between two model distributions: Borealis conditioned on the system prompt, and the same base model augmented with the LoRA adapter but evaluated without the system prompt in context. This objective encourages the adapter to reproduce the behavioral effects of the prompt without requiring the prompt to be present at inference time.

To reduce degradation on downstream tasks and preserve general model utility, we merge the resulting prompt adapter into the base model using a scaling factor of 0.25, which we found to provide the best empirical trade-off.

Intended Use

Norwegian-centric assistant-style tasks, including drafting, summarization, Q&A, and light reasoning (this is not a reasoning model).
Assessment and improvement of Norwegian writing style and quality.
Evaluation of behavior and language coverage for Norwegian, Bokmål, and Nynorsk.

Usage

This repository contains GGUF files for NbAiLab/borealis-open-1b. For Transformers or vLLM serving from safetensors, use the main model repository: NbAiLab/borealis-open-1b.

llama.cpp

Run a GGUF directly from the Hub:

llama-server -hf NbAiLab/borealis-open-1b-gguf --port 8080

Or download a GGUF file and run it locally:

llama-cli -m borealis-open-1b-Q4_K_M.gguf \
  -p "Skriv et kort sammendrag av hva Nasjonalbiblioteket gjør." \
  -n 256

Ollama

Run the GGUF repository from Hugging Face:

ollama run hf.co/NbAiLab/borealis-open-1b-gguf

For a local GGUF file, create a minimal Modelfile:

FROM ./borealis-open-1b-Q4_K_M.gguf

Then create and run the local Ollama model:

ollama create borealis-open-1b -f Modelfile
ollama run borealis-open-1b "Skriv tre korte punkter om norsk språkteknologi."

Limitations

The model may hallucinate or produce incorrect information.
Safety alignment reduces but does not eliminate harmful or inappropriate outputs.
Performance outside Norwegian and English use cases has not been fully characterized.

EU AI Act

The model is a fine-tune of Gemma 3. Using Gemma 3 27B as a conservative upper-bound reference, the original Gemma 3 27B training compute is estimated at approximately 2.1-2.3 x 10^24 FLOPs, based on the disclosed 14T training-token budget and the 27B parameter scale. The fine-tuning run used approximately 3.4 x 10^20 FLOPs, or about 0.015% of the estimated original training compute. This is substantially below the European Commission's indicative one-third threshold for treating a downstream modification as a significant modification that would make the modifier the provider of the modified General Purpose AI (GPAI) model.

On that basis, the fine-tuning activity is preliminarily assessed as not constituting a substantial modification for the purpose of becoming the provider of a new modified GPAI model under the compute-based criterion. However, the resulting model remains derived from a generative general-purpose AI model and may still be subject to downstream AI-system obligations under the EU AI Act.
