Lumo-1-Chat is a full fine-tune of Apertus v1.1 1.5B Instruct model.
Update to V2: builds on the original Lumo training, added examples broaden coverage of summarization, information extraction, explanation, rewriting, and instruction following.
V2 is published separately from V1 so the original model remains available.
Responses can be inaccurate, repetitive, or unsafe. Verify important information independently.
