Model Card
Dots3-Note Preview is a multimodal mixture-of-experts model from Dots Studio, the AI lab at Xiaohongshu (RedNote), also behind the dots.llm and dots.ocr models released under the rednote-hilab name. It has 280 billion total parameters, 16 billion active per token, and accepts text, image, video, and audio input.
The model introduces TEMPO, a reinforcement learning method for long-horizon agent tasks. It periodically checks its own progress and updates its memory while working, targeting agents that operate over hours.
Dots Studio reports 78.4% on SWE-bench Verified and 79.1% on MMMU Pro, and says a checkpoint scored a perfect 42/42 on the 2026 International Mathematical Olympiad, matching Huawei's Celia and beating Gemini Deep Think's 35/42 at the same event. These are vendor-reported figures, not yet independently verified.
This free-tier listing is served through OpenRouter, with a 512K-token context window suited to long documents, codebases, and multi-step agent workflows.
