AI PhD student at @univienna with @sebschu Interested in LLM Agent Evaluation, Human-Agent Interaction

Joined October 2023
Excited to be presenting this paper tomorrow at #EMNLP2026! Feel free to stop by and say hi, happy to chat about agents and human-agent collaboration 😊 πŸ“ Poster Session C (Hall H) πŸ—“οΈ Oct 26th, 9:00–10:30 AM w/ @sebschu xitter.cf/nedwards99/status/2098…
Excited to share that "Ask or Assume?" has been accepted to EMNLP 2026 Findings! πŸŽ‰ We show that coding agents can be turned into proactive collaborators that independently know when to ask for help on real-world coding tasks.

was excited to see RExBench shoutout by Lillian Lee during the #EMNLP2026 plenary panel! we also think it's undercited and i suspect we might already be in the "harder to spot implicit errors" zone of model capabilities. Give it a read if you haven't already :) (link in thread)

Nice to see more benchmarks built around research extensions! πŸ¦–
πŸ§ͺCan AI agents take a scientific paper and write a meaningful follow-up to it? We introduce Into the Unknown, an AI agent benchmark of 15 open scientific research problems. Each problem comes from a scientist currently or formerly at US DOE National Labs: @LosAlamosNatLab @SandiaLabs @BerkeleyLab @AmesNatLab @PPPLab @Livermore_Lab

Our rookie mistake was to not attach a vibe probability to this claim. (Quote from: arxiv.org/abs/2506.22598)
Congrats to everyone with papers accepted to #NeurIPS. I am thrilled to share that we successfully withdrew one of our #ICLR submissions, because we caught a serious evaluation error before submitting the #slop. Story: We used Codex/Claude Code to help design and debug LLM evaluations on modest GPUs. When we hit OOM errors, Claude Code suggested several fixes, including reducing the max output-token budget. Tired of auditing every suggestion, we approved it. Two months later, while analyzing the results, we discovered that this β€œsmall” change substantially altered the evaluation outcomes. The reduced generation budget became a major confound and made our method look much better than it actually was. We thought we had made significant progress. BUT it was, to a large extent, an evaluation artifact. AI can accelerate research. It can also accelerate confounding. And thanks to AI who helped us confirmed the error... NOTE: Image is AI-generated for illustration only; all numbers are made up but the story is true.

In the updated version, we also evaluate the open-weight frontier model Kimi K2.6, demonstrating that the findings generalize across model families.

🧡 Do coding agents know when to ask for help? Real-world coding tasks are rarely fully specified, yet most agents are optimized to execute autonomously rather than clarify.

Why do LLMs fail in massive document streams? 🌊 Do they fail to find the right information, or fail to reason over it? Excited to share that our paper answering this question has been accepted to KDD 2026! πŸŽ‰

We finally found the @ViennaNLP account details again πŸ˜… Here’s a photo of some of the group at #ACL in San Diego a few weeks ago! (missing here is @sebschu, who'd already headed off for lunch!) #ACL2026 #nlproc

Introducing Harbor-Index, a compact, diverse, and high-quality benchmark built to challenge frontier agents. We carefully select, audit and fix 82 high-signal tasks out of 6,627 candidates spanning 54 benchmarks. No agent gets above 30%. (1/5)

RExBench is now available in Terminal Bench (@harborframework)! πŸŽ‰ We integrate 2 tasks (cogs, othello) along with a local testing framework so you can test if your agents can autonomously implement novel AI research extensions.

Can coding agents autonomously implement AI research extensions? We introduce RExBench, a benchmark that tests if a coding agent can implement a novel experiment based on existing research and code. Finding: Most agents we tested had a low success rate, but there is promise!
