Borealis 4B Instruct (Preview)

NbAiLab/borealis-4b-instruct-preview is a 4-billion parameter instruction-tuned model, released as a preview for early testing and feedback. It is an experimental model based on the google/gemma-3-4b-it architecture, fine-tuned solely on textual instructions using the NbAiLab/aurora-sft-2512 dataset.

Key Characteristics

• Preview Quality: This is a pre-release model, and its outputs may be unstable or prone to hallucination.
• Norwegian Focus: Specifically intended for tasks requiring Norwegian language understanding and generation.
• No Safety Alignment: Crucially, this model has not undergone safety alignment and may produce harmful, biased, or inappropriate content. It is not suitable for safety-critical applications without additional mitigations.

Intended Use Cases

• Norwegian Assistant Tasks: Ideal for drafting, summarization, question-answering, and light reasoning in Norwegian.
• Writing Style Assessment: Useful for evaluating Norwegian writing style and quality.
• Early Evaluation: Designed for assessing model behavior, language coverage (Bokmål/Nynorsk), and overall quality in a Norwegian context.

Available Formats

The model is available in various formats, including Transformers (safetensors), GGUF quantizations (q8_0, f16, bf16), and MLX for Apple Silicon (32-bit and 8-bit quantized).
