Xiaohongshu's (RedNote's) in-house AI lab, launched in early 2025 out of its LLM team and formerly known as Hi Lab.
First open-weight release was dots.llm1 (June 2025), a 142B-total / 14B-active MoE; dots.ocr (July 2025) is a 1.7B multilingual document parser.
Promoted to a first-level 'Dots' AI department inside Xiaohongshu in April 2026.
A dots-note-3.0 branch inside a bespoke proof harness posted a perfect 42/42 at IMO 2026; the published dots3-note Preview checkpoint is not that system.
