DoorDash’s new AI chatbot lets you order with prompts and photos
The new chatbot, called Ask DoorDash, allows users to search the app for what they're looking for in their own words instead of having to scroll through restaurants and stores to build a cart.
DiffusionGemma: Google’s Diffusion-Based Open Model for Faster Text Generation
Large language models usually generate text one token at a time. While this autoregressive approach delivers strong quality and instruction following, it can be inefficient for local users because GPUs often spend more time moving weights from memory than doing parallel compute. Google DeepMind’s Di...
Text classification typically boils down to scenarios where a product review is "positive" or "negative", or a customer inquiry belongs to one category or another.
The benchmark gap, explained: What AI leaderboards measure and what they miss
Every frontier model now scores above 88% on MMLU. So why does a 37% gap still exist between lab benchmark scores and real-world AI deployment performance? We explain why the tests keep lying, and what rigorous evaluation actually looks like.
Google DeepMind is worried about what happens when millions of agents start to interact
Google DeepMind is funding research into the potential dangers of millions of different AI agents interacting with each other online. According to Rohin Shah, who directs the company’s AGI safety and alignment research, the mass-market arrival of agents that can carry out tasks without human oversig...

Restless bandits with imperfect binary feedback: PCL-indexability analysis and computation
arXiv:2606.11192v1 Announce Type: new
Abstract: We study restless bandits with binary latent states and imperfect binary feedback, motivated by opportunistic spectrum access with sensing errors. For the associated belief-state model, we develop a partial conservation laws (PCL)-based analytical and...
To Intervene or Not: Guiding Inference-time Alignment with Probabilistic Model Blending
arXiv:2606.11201v1 Announce Type: new
Abstract: The wide deployment of LLMs has made model alignment necessary to make newly trained models safely and effectively respond to user instructions. Among different methods, inference-time alignment is often cheaper as it intervenes (i.e., offers guidance...
Dual-Stance Evaluation of Sycophancy: The Structure of Agreement and the Limits of Intervention
arXiv:2606.11205v1 Announce Type: new
Abstract: Activation steering can shift LLM behaviour, but standard evaluations do not typically test whether a sycophancy-reduction direction also suppresses agreement with factually correct statements. We introduce dual-stance evaluation, which tests both sta...
ProHiFlo: Hierarchical Flow Matching with Functional Guidance for De Novo Protein Generation
arXiv:2606.11243v1 Announce Type: new
Abstract: De novo protein generation has transformative potential in therapeutic design, enzyme engineering, and synthetic biology. While diffusion-based and flow matching approaches have achieved progress, they typically operate at single resolution and lack m...
