New preprint: arxiv.org/abs/2603.20133 Does performance on reasoning benchmarks transfer to real-world settings such as task-oriented dialogue? Not necessarily: our new benchmark tests LLMs on problems framed in both standalone and dialogue settings, and shows that dialogue makes reasoning harder.

If you think labeling text spans with LLMs is easy, you probably have not tried it yourself (we have! 🙃). Any method you can think of – be it tagging, matching, or indexing – has flaws. In our new preprint, we tested them all 💪We also proposed how to improve one of them. arxiv.org/abs/2601.16946
