Sommerfugl-31B-v2 — GGUF

GGUF builds of Sommerfugl-31B-v2, a Norwegian language model by oolabs.no, for local use with llama.cpp, Ollama and LM Studio.

Built with Gemma. Sommerfugl-31B-v2 is a finetune of google/gemma-4-31B-it, modified by oolabs.no. Use is governed by the Gemma Terms of Use.

Results, known limitations and intended use are on the main model card. The chat template is embedded in every file.

Thinking mode is not supported. Sommerfugl is trained for direct answers; the embedded chat template always runs in non-thinking mode, so no extra flags are needed.

Files

file	quant	size	notes
`sommerfugl-31b-v2-Q4_K_M.gguf`	Q4_K_M	~19 GB	default; fits a 24 GB GPU or a 32 GB Mac
`sommerfugl-31b-v2-Q5_K_M.gguf`	Q5_K_M	~22 GB	a little closer to full quality
`sommerfugl-31b-v2-Q8_0.gguf`	Q8_0	~33 GB	near full quality

Quantization changes outputs slightly; the benchmark numbers on the main card are for the full-precision weights.
