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 π

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 :)

Nice to see more benchmarks built around research extensions! π¦
π§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:

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 βsmallβ 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.

Harbor Adapters and Harbor-Index (previously named as harbor-mix) accepted at NeurIPS E&D! Congrats and special thanks to all of our contributors, advisors, and funding partners!
Excited to share that "Ask or Assume?" has been accepted to EMNLP 2026 Findings! π
We show that coding agents can be turned into proactive collaborators that independently know when to ask for help on real-world coding tasks.
In the updated version, we also evaluate the open-weight frontier model Kimi K2.6, demonstrating that the findings generalize across model families.

Why do LLMs fail in massive document streams? π
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! π

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)

On my way to San Diego for #acl2026nlp now!
My PhD Student @nedwards99 (along with BU colleagues @yukyunglee_ and @audreymao100
) will present our poster on evaluating Coding agents on novel research tasks on Tuesday at 9:00am.

Excited to share that RExBench has been accepted to ACL main! ππ
RExBench is now available in Terminal Bench (@harborframework)! π
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.
Thanks to @Mike_A_Merrill and @alexgshaw for early discussions, and to @LinShi592021 and the Adapters team for help with integration!
