Exciting new paper! 🚨 Why Do Reasoning Models Lose Coverage? We revisit this open question with a data-centric lens 🔍 , and show how “forks in the road” situations in the post-training data can shape—and shrink—model coverage ⤵️

We are pleased to announce the launch of the TRIDENT Grand Challenge @ ACM Multimedia 2026 in Rio de Janeiro. As generative AI continues to advance, deepfakes are rapidly evolving from simple image manipulations into highly realistic multimodal content spanning images, videos, and cloned audio. The rapid progress raises an important challenge for current detection systems: while many models can successfully identify fake content, they often remain black-box systems, offering limited insight into the evidence or reasoning behind their decisions. TRIDENT is designed to address this gap by encouraging more interpretable and evidence-grounded multimodal deepfake analysis. 🔥 The challenge is now in Phase 2, with test sets released and the online leaderboard open for submissions. 📌Challenge Tracks • Image deepfake analysis • Video deepfake analysis • Audio deepfake analysis Participants may choose to compete in one or multiple tracks, depending on their research interests. 📌Core Capabilities The challenge focuses on three key abilities: • Deepfake detection • Fine-grained artifact perception • Evidence-based reasoning without hallucination Participants will engage with structured and open-ended tasks designed to evaluate both forensic understanding and reasoning quality in multimodal settings. 🏆Top-performing teams from each track will be invited to submit a technical paper to the ACM MM 2026 main conference proceedings. 📅 Important Dates (AOE): • Registration Deadline: June 1, 2026 • Final Submission Deadline: June 10, 2026 • Winner Announcement: June 15, 2026 --- More details and participation information are available here: tridentatmm26mgc.github.io/t… We warmly welcome the research community to join us in advancing trustworthy multimodal AI forensics!

NeurIPS 2026 is accepting submissions for Workshops!

We want to speak directly to the concern many of you have expressed, and we owe you a clear explanation of what happened, why it happened, and where we stand now. We understand this situation caused genuine alarm and we take that seriously. In preparing the NeurIPS 2026 handbook, we included a link to a US government sanctions tool that covers a significantly broader set of restrictions than those NeurIPS is actually required to follow. This error was due to miscommunication between the NeurIPS Foundation and our legal team; there was never an intention to restrict participation beyond our mandatory compliance obligations. The responsibility for that error is ours as an organization, and we deeply apologize for the alarm and impact this miscommunication had on our community. We have updated the link and clarified the text of our policy, which is consistent with that of ACM and IEEE, as well as other international conferences and NeurIPS in the past. As in previous years, NeurIPS welcomes submissions from all compliant institutions and individuals. We want to reiterate that NeurIPS is a community-driven event, created by and for the community, and strives to be inclusive. The NeurIPS 2026 organizing committee was particularly saddened to learn of this institutional miscommunication. The organizing committee has taken on the responsibility of running the conference this year with the goal of fostering open communication, knowledge sharing, and global scientific discourse. We thank the community for bringing this issue to our attention and working with us through this situation.

Official @NeurIPSConf statement (from website): The NeurIPS Foundation, like any entity operating within U.S. legal jurisdiction, is required by law to comply with U.S. sanctions and trade restrictions. Under these regulations, providing 'services' (which would include peer review, editing, and publishing) to Specially Designated Nationals and Blocked Persons, or "SDNs", is strictly prohibited. Consequently, we are unable to accept or publish submissions from any SDN, or any individual or institution that NeurIPS reasonably believes represents or is affiliated with an SDN. The US State Department's Office of Foreign Asset Controls maintains a searchable website that lists all SDNs. NeurIPS will consider submissions from institutions and individuals that the US State Department has categorized as "Non-SDN". sanctionslist.ofac.treas.gov…
