On October 5th @trsaenger and I will give an oral presentation at @textasdata at @UCBerkeley.

We’re incredibly excited to present "APPEAL: Attributing Persuasive Power to Expert-Specified Actions in LLMs"

This is joint work with @GiladMorad12, @ofraam, and @b_m_stewart

The paper, the code, the model and a summary, in one place:

Tool-using agents do what they are asked. Yet a task often needs information the user never mentions.

What should an agent go after unasked, and can we train it to?

New paper, code and model, with @AsafYehudai @segevshlomov Asaf Adi @LChoshen

[Ido Levy @Idolevy31]

Still open: it learned what to ask more readily than when to stop, and the extra evidence doesn't yet turn into better final answers.

Code, need-graph metrics, 5,000+ tests and both trained seeds are open.

🚨New Paper (ACL-26)
'Efficient Agent Evaluation via Diversity-Guided User Simulation'

We tackle a core pain in agent evaluation:
Current methods aim for coverage (pass@k) but mostly re-run the same conversations → low diversity, high cost.

We're excited to introduce DIVERT 🧵

@langer_han The same here, asked for two more experiments (which are complex and completely out of scope) and still ghosted..

[Ido Levy @Idolevy31]

@lightetal Some of them decided not to rebut and didn't withdraw.

Come by our poster (#1111) tomorrow at 11am to talk about VLMs!

[Dana Arad @dana_arad4]

On my way to @emnlpmeeting! If you’re into interpretability and/or vision–language models, let’s chat 🤩

[Ido Levy @Idolevy31]

@dana_arad4 @emnlpmeeting Great work, have fun!

@DailyMirror The Daily Mirror took Karim Muammer’s photos from Anadolu Agency, but left out an important detail from the original report – he suffers from Fanconi syndrome, a rare genetic condition that affects the kidneys, liver, and intestines, causing poor nutrient absorption.

🚨New paper alert🚨

🧠
Instruction-tuned LLMs show amplified cognitive biases — but are these new behaviors, or pretraining ghosts resurfacing?

Excited to share our new paper, accepted to CoLM 2025🎉!

@Itay_itzhak_ Very interesting! Thanks for sharing!
