🤔 AI agents can do a lot once you give them a task. Can they also figure out what’s worth doing and get started before being asked? 🏫 That’s the question behind Proactive AI for Superintelligent Agents, our joint survey by researchers from UIUC, Google, Stanford, UC Berkeley, and CMU. Our backgrounds span AI agents, embodied AI, information retrieval, computational biology, economics, and finance. 🕵 As finding papers gets cheaper, we think a survey’s value increasingly comes from hard-earned research intuition: knowing what matters and what to try next. Contributors drafted the sections closest to their own research, then refined them through several rounds of discussion and revision across research backgrounds. 📃 Paper: empathyang.github.io/Proacti… 🌎 Website: empathyang.github.io/Proacti… 💼 Google Research: research.google/pubs/proacti… More in the video below 👇

Proactive AI is undoubtedly the future of AI agents. Exciting to see Anthropic’s Claude moving in this direction with proactive agents! We recently explored proactive AI for superintelligent agents in our latest survey with Google, Stanford, UCB and CMU. Check it out: research.google/pubs/proacti…
We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.

🔥 Excited to share Agent World Model in the Wild (WildAWM)! 🌍 Fully open-source synthesis 🔓: No proprietary models needed! We synthesized 341 high-quality environment–task pairs, addressing 3 challenges in task synthesis: ✅ Solvability: At least one agent can successfully complete each task. 🔥 Difficulty: Challenging even for frontier models, with GPT-6-Astra achieving only ~72.7 pass@8. 🎯 Verifier reliability: 95% agreement between task verifiers and agent-as-a-judge ensemble. 📈 Effective RL training: Trained exclusively in these synthetic worlds, Qwen3.6-35B-A3B achieves an average +10.58-point improvement across 8 OOD benchmarks!

🤩 Introducing Self-HPO: let the coding agent improve its own harness, then train a stronger policy model with the optimized harness, and repeat the process for recursive improvement! 💪 Self-evolving: no external model required 🎯 Harness search targets the policy's evolving failure modes 📈 Avg over SWE-Bench Verified/Multilingual/Pro: 57.8% → 64.8% 🧵[1/n]

SFT erodes backdoors. RL can preserve or even amplify what remains. This means an LLM agent can inherit a backdoor from a third-party model and retain it even after substantial benign post-training. In our new EMNLP 2026 Findings paper, we study how backdoors behave under SFT and RL, identify factors associated with their persistence, and show how an attacker can make them more persistent.

🔥 New: An assistant that knows your goals and keeps working before you ask is becoming a real product category, e.g., Muse/Dots. But asking an agent to act without a new prompt raises a lot of questions. How should it infer what matters? When should it interrupt? What actions can it take without approval? Our recent survey from UIUC, Google, Stanford, UC Berkeley, and CMU puts those lines of proactive AI research next to each other. research.google/pubs/proacti…

Grateful to Microsoft Research for featuring our work, StudentSim! Since its release, we've been amazed by the attention it has received, not only from the education community, where professors have called it "the very first foundational work in this area" and shared that they'd envisioned this direction long before data and training made it possible, but also from researchers and project leads working on user simulation in recommender systems, healthcare, and financial services. It's exciting to see a shared recognition of the importance and potential of user simulation for personalized AI services. Hope StudentSim can be a useful stepping stone for the community!

In 1995, Wooldridge and Jennings listed proactiveness among the basic properties of intelligent agents. 31 years later, our agents can reason, code, and run complex workflows. Yet someone still has to notice the work and tell them to start. We think this is a major gap. 1/7 It's easy to miss the problem when agents are judged on a task they've already been given. A long open-ended project is different. Instructions are incomplete, plans fail, priorities change. Humans still decide what to investigate and when to change course. That won't scale forever. 2/7 There's also a product shift underway. Meta's Muse and OpenAI's dots both point toward proactive agents that keep track of goals, anticipate needs, and work beyond a single chat session. We expect users to ask less often for individual tasks and more often for continuing progress. 3/7 Proactiveness isn't a new idea. Relevant work spans agent theory, planning, HCI, robotics, ubiquitous computing, and LLM agents. Communities have developed different terms and benchmarks for related problems. It's surprisingly hard to get a clear picture of the field. 4/7 We felt this was a good moment to put those threads together. 23 of us from UIUC, Google, Stanford, UC Berkeley, and CMU worked on a survey, with backgrounds spanning agents, robotics, retrieval, computational biology, and finance. 5/7 We tried to write it differently from a bibliography dump. Chapters were drafted by people closest to the topic, then discussed and revised across backgrounds. When searching for papers is becoming cheap, the harder work is deciding which connections are meaningful. 6/7 The resulting survey organizes proactive agents around 6 capacities: awareness, anticipation, agenda formation, arbitration, action, and adaptation. We also review evaluation at three levels and compare initiative with action authority across 13 domains. 7/7 We don't expect this to be the final map of the area. We'd be happy if it helps people find a question worth working on, or shows them where to disagree with us.

Happy to share that the full version of EvoHarness-RL from @Meta, UIUC, and CMU is now out, together with our code and project page! We substantially expanded the study across 3 long-horizon benchmarks: ALFWorld, WebShop, and WebArena. EvoHarness-RL consistently improves over strong trainable baselines, with +8.5 pts average success. Our unified BPE harness also improves frontier models by +10.0 pts on average, without any training. One interesting insight is that as RL progresses, agents gradually internalize recurring harness-use patterns and learn to selectively retain the external state that is actually useful, resulting in different harness behaviors across environments. Feel free to repost, and if you find the code useful, we’d really appreciate a GitHub star ⭐️ We’ll share more findings in follow-up posts soon! We’re also presenting EvoHarness-RL at the @COLM2026 LLA Workshop this afternoon. Feel free to stop by and check out our poster! 🌐 Webpage: evoharnessrl.github.io/ 📄 Paper: arxiv.org/pdf/2608.05446 💻 GitHub: github.com/EvoHarnessRL/EvoH…
New research from Meta. Agent harnesses are still mostly authored by hand. This makes it hard to tune robust agent harnesses for long-horizon tasks. In this new work, agents learn harness policies offline and deploy them to construct and update external harness state online during runtime task execution. EvoHarness-RL learns that policy instead. Belief, Progress, and Experience are exposed as harness state the policy can act on. Supervised harness fine-tuning teaches the action space, then cost-aware GRPO explores when to read, update, and consolidate during a long run. Qwen3-8B reaches 96.9% on ALFWorld. Two dynamics come out of the training. > Harness annealing means recurring harness-use patterns get absorbed into the model policy, and the agent shifts from frequent calls toward selective access. > Harness evolution means progress updates and experience consolidation compress the workspace into a compact task-adaptive state. This shows that long-horizon agents get more from a trainable coordination policy than from bigger tools or larger memories.

16/17 Future work on agent proactiveness spans capabilities, governance, and applications. Capabilities improve how agents anticipate needs, choose work, decide when to act, and learn from feedback. This includes broader evaluation and studying how initiative supports long-horizon tasks and agent self-improvement. Governance builds safeguards throughout reasoning, execution, and learning, with understandable decisions, clear consent, and accountability. Users need practical ways to inspect, correct, or stop unwanted initiative. Applications explore personal agents, embodied agents, and networks of agents that can initiate and coordinate work. The survey also considers how institutions and everyday practices may need to adapt.
