dots studio, the model lab inside rednote (Xiaohongshu), released weights for dots3-note-preview on Aug 14 and announced it Aug 16 — the first open-weight release in the dots3 family, which includes the model that took a perfect 42 at the 2026 International Mathematical Olympiad. It is a 280B-total / 16B-active MoE with a 512K context window and text, vision and audio understanding, tuned for long-horizon agent tasks. 'note' is the lightest of a planned three-tier series (note, jazz, aria); weights are on Hugging Face at dots-studio/dots3-note-prev.
