Borealis 27B Instruct (Preview)

NbAiLab/borealis-27b-instruct-preview is a 27-billion parameter instruction-tuned model from NbAiLab, released as a preview for early testing and feedback. This experimental model is based on the google/gemma-3-27b-it architecture and has been fine-tuned solely on textual instructions using the NbAiLab/aurora-sft-2512 dataset.

Key Characteristics

• Preview Quality: This is an experimental, pre-release model, meaning outputs may be unstable and prone to hallucinations.
• Norwegian Focus: Specifically fine-tuned for Norwegian-centric assistant tasks, including drafting, summarization, Q&A, and light reasoning.
• Safety Disclaimer: The model has not been safety-aligned and may produce harmful, biased, or insensitive content. It is not suitable for safety-critical applications without additional mitigations.

Good for

• Early evaluation of model behavior and language coverage for Norwegian (Bokmål / Nynorsk).
• Assessment of Norwegian writing style and quality.
• Non-safety-critical assistant-style tasks in Norwegian contexts.
• Developers interested in providing feedback on an experimental instruction-tuned model.
