Lynx 2B (micro)

Model Details

Model Description

This is the first release of a series of Swedish large language models we call "Lynx". Micro is a small model (2 billion params), but punches way above its weight!

Lynx micro is a fine-tune of Google DeepMind Gemma 2B, scores just below GPT-3.5 Turbo on Scandeval. In fact, the only non OpenAI model (currently) topping the Swedish NLG board on scandeval is a fine-tune of Llama-3 by AI Sweden based on our data recipe.

We believe that this is a really good model (for its size), but keep in mind that it is still a small model and hasn't memorized as much as larger models tend to do.

• Funded, Developed and shared by: 42 Labs
• Model type: Auto-regressive transformer
• Language(s) (NLP): Swedish and English
• License: Gemma terms of use
• Finetuned from model: Gemma 2B, 1.1 instruct
