From IMO gold-medal-level reasoning to real-world agency. 🥇🌍 👇 Read the thread for the model and open-source links. Built by rednote, @dotsstudioai’s dots3-note preview is an open-weight multimodal model designed for long-horizon agency in real life. It proves its reasoning ability by moving beyond just answering questions — helping AI sustain reasoning, adapt through interaction, and execute actions across complex, ever-changing tasks.

2/ 🧠 Train agents for tasks that last hours—not minutes. Say hello to TEMPO. By splitting long trajectories into macro-steps, it helps agents stay on track by switching between Actor and Critic—assessing progress and course-correcting before the task concludes. During a hidden-rule game, two distinct branches secured the exact same reward after 64 rounds. Yet the Critic caught what the raw reward missed entirely: Branch B misunderstood the objective and kept going in the wrong direction. Branch A found the underlying conflict rule and moved toward a feasible solution. Branch A: 3.8 | Branch B: 2.29 Equivalent reward. Very different progress.

4/ 🔁 Learn in unfamiliar environments. Through interaction and feedback, dots3-note preview can: Explore → Form & test hypotheses → Update memory → Reuse what it learns This adaptive capability shines in extended interactive scenarios like ARC-AGI-3.

5/ Open-source the tools. Try the model. 🔎 VibeSearchBench — multi-turn search as user intent unfolds vibebench.github.io/VibeSear… 🌎 VibeLifeBench — long-running tasks where users, plans, and conditions change over time vibebench.github.io/VibeLife… We are releasing two open benchmarks designed to evaluate real-life agents on extended tasks. dots3-note preview is just the first step.
