We analyzed 250K queries & 430K clickstream interactions from Asta, our AI-powered research assistantโ€”and today we're releasing the full dataset. How do researchers actually use AI science tools? Here's what we found. ๐Ÿงต

๐Ÿ†• New in Asta: multi-turn report generation. You can now have back-and-forth conversations with Asta, our agentic platform for scientific research, to refine long-form, fully cited reports instead of relying on single-shot prompts.

Last year I worked at @Adobe @AdobeResearch and @allen_ai, exploring how we can help users read, organize and understand long documents. This piece covers what we learned on modelling user intent and combining LLMs with principled tools when building complex pipelines for it!
CDS PhD alum Vishakh Padmakumar (@vishakh_pk), now at @Stanford, tackled the hard part of summarization โ€” deciding what matters. At @Adobe, he built diversity-aware summarizers; at AI2 (@allen_ai), intent-based tools for literature review tables. nyudatascience.medium.com/suโ€ฆ

Producing reasoning texts boosts the capabilities of AI models, but do we humans correctly understand these texts? Our latest research suggests that we do not. This highlights a new angle on the "Are they transparent?" debate: they might be, but we misinterpret them. ๐Ÿงต

People at #ACL2025, come drop by our poster today & chat with me about how context matters for reliable language model evaluations! Jul 30, 11:00-12:30 at Hall 4X, board 424.
Excited to share โœจ Contextualized Evaluations โœจ! Benchmarks like Chatbot Arena contain underspecified queries, which can lead to arbitrary eval judgments. What happens if we provide evaluators with context (e.g who's the user, what's their intent) when judging LM outputs? ๐Ÿงตโ†“
