⚠️Different models. Same thoughts.⚠️ Today’s AI models converge into an 𝐀𝐫𝐭𝐢𝐟𝐢𝐜𝐢𝐚𝐥 𝐇𝐢𝐯𝐞𝐦𝐢𝐧𝐝 🐝, a striking case of mode collapse that persists even across heterogeneous ensembles. Our #neurips2025 𝐃&𝐁 𝐎𝐫𝐚𝐥 𝐩𝐚𝐩𝐞𝐫 (✨𝐭𝐨𝐩 𝟎.𝟑𝟓%✨) dives deep into this phenomenon, introducing 𝐈𝐧𝐟𝐢𝐧𝐢𝐭𝐲-𝐂𝐡𝐚𝐭, a real-world dataset of 26K real-world open-ended user queries spanning 17 open-ended categories + 31K dense human annotations (𝟐𝟓 𝐢𝐧𝐝𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐭 𝐚𝐧𝐧𝐨𝐭𝐚𝐭𝐨𝐫𝐬 𝐩𝐞𝐫 𝐞𝐱𝐚𝐦𝐩𝐥𝐞) to push AI’s creative and discovery potential forward. Now you can build your favorite models to be truly original, diverse, and impactful in the open-ended real world. 📍Paper: arxiv.org/abs/2510.22954 📍Data: huggingface.co/collections/l… We also systematically reveal Artificial Hivemind across: 💥 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐚𝐛𝐢𝐥𝐢𝐭𝐢𝐞𝐬: not only do individual LLMs repeat themselves, but different models produce strikingly similar content, even when asked fully open-ended questions. 💥 𝐃𝐢𝐬𝐜𝐫𝐢𝐦𝐢𝐧𝐚𝐭𝐢𝐯𝐞 𝐚𝐛𝐢𝐥𝐢𝐭𝐢𝐞𝐬: LLMs, LM judges, and reward models are systematically miscalibrated when rating alternative responses to open-ended queries.

With nearly 30,000 registrants (including virtual), 64% increase since last year, they're saying that #NeurIPS2025 is the largest conference at San Diego Convention Center

Very cool resource by @davidbau: NDIF. Hosted models larger than 50B dedicated to explainability research, both through web and API. See layer activation, run traces, change weights, all through NDIF. Neat! David said this really well: most interpability research is done on far from SoTA models, and this could solve that. docs.google.com/presentation…

This is exactly why it will be the decade of agents, not the year of agents. Getting reliability in tasks that take 10h or 10 days will require environments and tasks with increasing complexity to get those needed nines of reliability. Exactly like self-driving cars.
Why can AIs code for 1h but not 10h? A simple explanation: if there's a 10% chance of error per 10min step (say), the success rate is: 1h: 53% 4h: 8% 10h: 0.002% @tobyordoxford has tested this 'constant error rate' theory and shown it's a good fit for the data chance of success declines exponentially

Saddened to learn of the death of Lila Gleitman, giant in language acquisition & dear friend. "Her depth of analysis is matched by experimental ingenuity, & her intellectual fierceness is expressed with wit, charm, & respect for those she disagrees with." en.wikipedia.org/wiki/Lila_R…

Let’s look at how flu actually spreads, day by day during an outbreak, in a defined population, such as a college. While many transmissions are cryptic (and nowadays identified via phylogenetic methods, eg by @trvrb), many transmissions occur via observed social network ties. 1/
