Bridging the divide: how AI scientists unite despite growing geopolitical rifts

Pak-Sun Ting, co-founder and CEO of Votee AI, described scientific collaboration as a "small undercurrent" countering geopolitical tensions at a Hong Kong gathering of AI innovators. While US-China rivalry frames AI as a zero-sum competition, developers argue its potential lies in expanding global capabilities. Ting emphasized that despite government disagreements, civilian and technological cooperation remains viable when permitted.

AI's most important protocol is getting a little bit easier to use

Arcade founder Nate Barbettini explained that the Model Context Protocol is receiving an update to adopt a "stateless" approach to session IDs on the server side. The current system requires individual servers to track session IDs across load-balanced deployments, creating difficulties for companies running MCP servers at scale. The upcoming change, with the spec public since May, aims to make the protocol easier to maintain and cheaper to operate, addressing infrastructure barriers that have limited large-scale MCP integrations.

LLMrPro is a self-hosted LLM router exposing one OpenAI-compatible API that routes requests to user-owned machines running local inference engines including LM Studio, Ollama, vLLM, llama.cpp, and MLX. When local workers cannot serve a request, it falls back to configured cloud providers such as OpenAI, Anthropic, Google, or Azure OpenAI. The system is single-tenant, with encrypted provider keys and per-source rate limiting. A balancer and desktop agent comprise the two installable components.

The ad follows a marketing playbook where a brand owns industry harms to position itself as responsible, but critics, including tech industry workers, called it poorly executed. Anthropic previously ran humorous Super Bowl ads targeting OpenAI.

Sharp Optimal Algorithm for Derivative-Free Stochastic Convex Optimization in One Dimension

The paper presents an algorithm achieving the optimal convergence rate for one-dimensional derivative-free stochastic convex optimization. The proposed method closes a persistent logarithmic gap between known upper bounds and the lower bound, delivering the first sharp rate guarantee in this setting. The algorithm is computationally efficient and matches the lower bound, addressing a problem where prior approaches fell short even in the simplest one-dimensional case.

Accelerated Mixing Time of Randomized Hamiltonian Monte Carlo

The paper proves that Randomized Hamiltonian Monte Carlo achieves "accelerated mixing time guarantees" for sampling from log-concave probability distributions. For targets satisfying an α-Talagrand inequality, using random integration times from triangular or exponential distributions yields convergence in KL divergence with total integration time scaling as O(α^{-1/2} log(ε^{-1})). For general log-concave distributions, triangular integration times with exponentially increasing means achieve O(ε^{-1/2}) total integration time. The analysis builds on bounds for average KL divergence along Hamiltonian dynamics.

The work proposes a "Representation-as-a-Judge" paradigm using INSPECTOR, a probing-based framework that predicts aspect-level evaluation scores from small model representations without decoding. Experiments on GSM8K, MATH, and GPQA show INSPECTOR outperforms prompting-based small LMs and closely approximates full LLM judges, offering a more efficient and interpretable alternative for scalable evaluation.

Validity of LLMs as data annotators: AMALIA on authority

AMALIA, a 9B-parameter European Portuguese model, agrees with human coders within six F1 points of models eight to thirteen times larger. However, researcher Manuel Pita found that when holistic prompts were decomposed into atomic clauses, AMALIA recovered only about half its performance, suggesting reliance on surface correlates. A calibrated English instrument did not transfer to AMALIA. The study argues sovereign-LLM benchmarks should test not only agreement with human coders but the evidential route warranting that agreement.

Group Invariant Spectral Embedding

Researchers Paulina Hoyos and Yeari Vigder propose incorporating symmetries directly into affinity kernels for spectral embedding, addressing a limitation of standard methods that treat symmetry-related data points as unrelated.

Validation on datasets with SO(2) or SO(3) symmetry confirms the approach recovers intrinsic geometry where standard methods fail.

A New Framework for Evaluating Voice Agents (EVA)

ServiceNow-AI researchers introduced EVA, a framework for evaluating conversational voice agents that jointly scores task accuracy and conversational experience across multi-turn spoken interactions. Developed by Tara Bogavelli, Gabrielle Gauthier Melancon, Katrina Stankiewicz, Nifemi Bamgbose, Hoang Nguyen, Raghav Mehndiratta, Hari Subramani, and Fanny Riols, EVA uses a bot-to-bot audio architecture with an initial airline dataset of 50 scenarios. Benchmarking 20 systems revealed a "consistent Accuracy-Experience tradeoff" between task completion and user experience.

Build a Domain-Specific Embedding Model in Under a Day

NVIDIA published a tutorial demonstrating how to fine-tune a general-purpose embedding model for domain-specific retrieval using a single GPU in under a day. The pipeline uses synthetic data generation, hard negative mining, and contrastive learning, requiring no manual labeling. Atlassian applied the recipe to its JIRA dataset, improving Recall@60 from 0.751 to 0.951, a 26% increase. NVIDIA reported over 10% improvement in Recall@10 and NDCG@10 on its own documentation dataset.

Measuring Progress Towards AGI: A Cognitive Framework

Google introduced a framework to measure progress toward AGI using cognitive science, detailed in a paper titled "Measuring Progress Toward AGI: A Cognitive Taxonomy." The framework aims to assess AI systems' cognitive capabilities through structured evaluation. Google also launched a Kaggle hackathon inviting participants to design evaluations for key cognitive abilities. The work involves Google DeepMind researchers Ryan Burnell and Oran Kelly.

AlphaGo at 10: How AI Innovation Is Paving the Path to AGI — Google DeepMind

Google DeepMind's AlphaGo became the first program to defeat a world champion at Go ten years ago, marking a milestone many experts thought was a decade away. The system's famous "Move 37" demonstrated AI's potential to find novel strategies beyond mimicking human expertise. AlphaGo used deep neural networks with advanced search and reinforcement learning. Google DeepMind states this breakthrough continues to inform its work toward artificial general intelligence.

Introducing Storage Buckets on the Hugging Face Hub

Hugging Face introduced Storage Buckets, non-versioned, S3-like object storage on the Hub designed for intermediate ML artifacts like checkpoints and logs. Backed by Xet, the chunk-based storage backend deduplicates content across files, reducing bandwidth and storage costs. A pre-warming feature partners with AWS and GCP to bring data closer to compute regions. Users can manage Buckets via the hf CLI or the huggingface_hub Python library.

Keep the Tokens Flowing: Lessons from 16 Open-Source RL Libraries

Hugging Face researchers surveyed sixteen open-source reinforcement learning libraries to guide the development of a new asynchronous trainer for TRL. The study compares these libraries across seven axes, including orchestration primitives, rollout buffer design, weight synchronization protocols, and staleness management. The team identifies GPU underutilization in synchronous training loops as a key motivation, noting that disaggregating inference from training onto separate GPU pools enables concurrent generation and gradient computation.

Ulysses Sequence Parallelism: Training with Million-Token Contexts

Hugging Face announced integration of Ulysses Sequence Parallelism across its ecosystem, including Accelerate, Transformers Trainer, and TRL's SFTTrainer. The method, part of Snowflake's Arctic Long Sequence Training protocol, distributes attention computation across multiple GPUs by partitioning attention heads. Kashif Rasul and Stas Bekman authored the announcement, which covers configuration, best practices, and benchmarks. The approach targets training with sequences extending to millions of tokens, addressing memory challenges that exceed single-GPU capacity.
