BlackboxNLP is back once again at EMNLP'26! Very happy to be part of the team again, and excited for our new reproducibility track! Check it out ⬇️

BlackboxNLP will be co-located with EMNLP 2026 in 🇭🇺 Budapest 🇭🇺 this October!

This edition will feature a special reproducibility track, investigating generalization and robustness of established results from interpretability research 👷‍♂️

Stay tuned for more details!

Nicolò & Mingyang: Can we understand which circuits emerge in small models and reasoning-tuned systems, and how do they compare with default systems? Are there methods that generalize better across all tasks?

Q: What's next for interpretability benchmarks? Michal: People sitting together and planning how to extend tests to multimodal, diverse contexts. @michaelwhanna.bsky.social: For circuit finding, integrating sparse features circuits could help us better understand our models.

Nicolò & Mingyang: Starting to explore notebooks and public libraries can be very helpful in gaining early intuitions about what's promising.

@michaelwhanna.bsky.social: Don't try to read everything. Find Qs you really care about, and go a level deeper to answer meaningful questions.

Q: How would one go about approaching interpretability research these days? Michal: "When things don't work out of the box, it's a sign to double down and find out why. Negative results are important!"

@danaarad.bsky.social: As deep learning research converges on similar architectures for different modalities, it will be interesting to determine which interpretability method will remain useful across various models and tasks.

@michaelwhanna.bsky.social, Nicolò & Mingyang: Counterfactuals in minimal settings can be helpful, but they do not capture the whole story. Extending current methods to long contexts, and finding practical applications in safety-related areas are exciting challenges ahead.

Michal: Mechanistic interpretability has heavily focused on toy tasks and text-only models. The next step is scaling to more complex tasks that involve real-world reasoning.

Our panel moderated by @danaarad.bsky.social
"Evaluating Interpretability Methods: Challenges and Future Directions" just started! 🎉 Come to learn more about the MIB benchmark and hear the takes of @michaelwhanna.bsky.social, Michal Golovanevsky, Nicolò Brunello and Mingyang Wang!

Next up: Kentaro Ozeki presenting "Normative Reasoning in Large Language Models: A Comparative Benchmark from Logical and Modal Perspectives" aclanthology.org/2025.blackbo...

After a productive poster session, BlackboxNLP returns with the second keynote "Memorization: Myth or Mystery?" by @vernadankers.bsky.social!

Nadav Shani is giving the first oral presentation of the day: Language Dominance in Multilingual Large Language Models. Find the paper here: aclanthology.org/2025.blackbo...

Next up: Circuit-Tracer: A New Library for Finding Feature Circuits presented by @michaelwhanna.bsky.social! Paper: aclanthology.org/2025.blackbo...

I'll be presenting this work at @blackboxnlp.bsky.social in Suzhou, happy to chat there or here if you are interested !
