🧵1/ Excited to share our #NAACL2025 work! 🎉 "Assessing LLMs for Zero-Shot Abstractive Summarization Through the Lens of Relevance Paraphrasing" We study how robust LLM summarization is to our relevance paraphrasing method? 🧠📝 More details below:👇 arxiv.org/abs/2406.03993

Can LLM guardrails think twice before deciding? ✨ Check out our #ACL2025 paper: THINKGUARD — a critique-augmented safety guardrail! ✅ Structured critiques ✅ Interpretable decisions ✅ Robust against adversarial prompts 📑 arxiv.org/abs/2502.13458 🧵[1/n]

😴 Extending modality based on an LLM has been a common practice when we are talking about multimodal LLMs. ❓ Can it generalize to omni-modality? We study the effects of extending modality and ask three questions: arxiv.org/abs/2506.01872 #LLM #MLLM #OmniModality
