Frequently asked question
Will this stay open?
What you have downloaded of the 8B stays yours under Apache 2.0, including for commercial use. The usage policy of the base model, the Apertus LLM Acceptable Use Policy, applies as well. Anyone may build on Walnoot, including a competitor. Openness is our philosophy. Later, larger models may come with different commercial terms. We make that distinction clear from the start.
