Proactive agents face a calibration problem: acting correctly is not enough if the intervention itself is poorly timed or unwarranted. We introduce HALO, a human-grounded benchmark for evaluating proactive agents across everyday environments. 📄 arxiv.org/abs/2610.39086 🧵 (1/5)

(5/5) HALO-8K contains 8,000 responses from 10 models, annotated by 20 experts for action level, acceptability, timing, intervention intensity, and rejection reasons. The evaluation is designed to capture not only what an agent does, but whether it should have acted at all.

ENCORE (Oral, NeurIPS 2026 Robot Learning Workshop; CoRL 2026 Agentic Robotics Workshop): a coding agent reads a few robot demos, writes a policy program, refines it, then freezes it. 96.3% on LIBERO-PRO, vs 89.3% for the best prior agent on the same model. arxiv.org/abs/2609.37359 yifank.github.io/encore

3/4 96.3% on LIBERO-PRO vs 89.3% for the strongest prior agent on the same model. When the instruction leaves the goal unstated, no program written without demos succeeds in any of three independent runs.

⚔️ We are pleased to introduce CyberArena, where we benchmark 12 frontier AI agents via letting them combat with each other in live attack-and-defense security contests. 🧵

🙌 This work is built in collaboration with Berkeley RDI, alongside researchers from UC Santa Cruz, UC Santa Barbara, UW-Madison, MIT, the University of Toronto, Johns Hopkins, CMU, Purdue, and Texas A&M. At 2077AI, we build open benchmarks that show both what frontier models can do and where they fall short. In that spirit, CyberArena’s engine, challenges and match replays are all open source.

Can agents organize without centralized control? In EoM, agents bid to act, earn from useful work, and go bankrupt when ineffective. Across 5 domains, specialist workflows emerge. Co-authored by researchers from Harvard, MIT, the Kempner Institute + 2077AI. zhentingqi.github.io/interna…
Leonard Read's pencil story: no one knows how to make a pencil from scratch, yet millions are made without a central manager. Each worker knows only their part. Incentives, not central control, coordinate their efforts. Current multi-agent AI seems to work the opposite way. A central manager does everything: assigns roles, writes the workflow, and decides who acts next. As agents increase and tasks get harder, that manager might become the bottleneck: it should understand every agent and every task, and adaptation becomes inefficient. So how can a group of machine agents organize themselves into something none of them could achieve alone? Further, how can that society of agents keep improving itself over time? In Economy of Minds (EoM), we show that simple local incentives can drive global self-coordination and self-improvement for modern LLM agents. We let agents live in a minimal economy: they compete for work, earn by helping others succeed, and go broke when they don't. Workflows, specialists, and improvement naturally emerge, with no one in charge. Across 5 domains (math reasoning, financial research, scientific research, accelerator design, and distributed-system optimization), limited agents grow into strong societies. The whole idea in a 90-second cartoon👇

What does a robot gain from 500 hours of human touch? On four contact-rich tasks, average success went from 22.5% to 57.5% after a training stage on human touch data, with no action labels. We present TouchScale, the largest human visual-tactile manipulation dataset to date. 🧵

TouchScale is a project co-led by researchers at Texas A&M University and 2077AI together with 14 collaborating institutions. Huge thanks to @EdisonLeeROC, @haohw_, Qianqian Yang, Zihao Zhu, @ZihanWang123, @Neutrino_l, @zhiwen_fan_ and all contributors who helped build it.
