How do scholars of diff backgrounds use and perceive the risks & benefits of LLMs as research tools? Are we willing to disclose to peers and reviewers? We conducted a large-scale survey of *verified authors* of different fields, race, gender, seniority to find out results in🧵

🤔Giving complex tasks to AI agents is easy—getting them to do exactly what you want isn’t. How can human-AI collaboration give us more reliable & steerable agents? 🍫Introducing Cocoa, our new interaction paradigm to balance human & AI agency in complex human-AI workflows. 🧵

How can we collaborate with AI agents on complex tasks (like doing research 👀) that require careful planning and execution? Definitely check out Cocoa where we introduce a novel co-plan and co-execute interaction pattern!

Can AI really help with literature reviews? 🧐 Meet Ai2 ScholarQA, an experimental solution that allows you to ask questions that require multiple scientific papers to answer. It gives more in-depth, detailed, and contextual answers with table comparisons, expandable sections

This is neat! I tried asking for a survey of "ways to steer AI-powered systems", and like the 3-part breakdown (model understanding, diagnostics, steering), seems useful, though the source is unexpected yet sensible (visual analytics). scholarqa.allen.ai/query/5fcf5c94…

New scientific QA system led by Sergey Feldman, Amanpreet Singh, Joseph Chee Chang, Aakanksha Naik and team from AI2 & UW! Following AI2/UW's prior open QA system (x.com/AkariAsai/stat…) by Akari Asai, this adds thematic clustering, tables, and the latest proprietary models.

🔬Research ideation is hard: After the spark of a brilliant initial idea, much work is still needed to further develop it into a well-thoughtout project by iteratively expanding and refining the initial idea and grounding it to relevant literature. How can we better support this?

We took our most efficient model and made an open-source iOS app📱but why? As phones get faster, more AI will happen on device. With OLMoE, researchers, developers, and users can get a feel for this future: fully private LLMs, available anytime. Learn more from Luca Soldaini 🎀👇

working with PDFs for LMs, errors in extracting content can be soul-crushing we need not just clean OCR but also correct reading order and structured info reprsentation our latest in tools for this, olmOCR is incredible! here's page 5 of our tech report as plain text w/ table🤯

AI agents are entering online social spaces, but often their messages feel generic or intrusive. In our #CHI25 paper, we introduce Social-RAG, a workflow that grounds AI generations in the specific group context by retrieving from the group’s interaction history. 🧵(1/9)

I am presenting IdeaSynth in the last paper session at #CHI2025 right now! Feel free to come by G314-315 to learn about how we utilize LLM to provide literature-grounded assistance for research idea development! The talk is happening at around 10:12 AM.

🆕paper: LLMs Get Lost in Multi-Turn Conversation In real life, people don’t speak in perfect prompts. So we simulate multi-turn conversations — less lab-like, more like real use. We find that LLMs get lost in conversation. 👀What does that mean? 🧵1/N 📄arxiv.org/abs/2505.06120
