Google Open-Sources XProf Kernel: A Deep Hardware Performance Analysis Suite for Custom TPU Kernels ↗

Google has open-sourced XProf Kernel, a low-level hardware debugging tool designed specifically for optimizing custom TPU kernels written in frameworks such as Pallas. It supports inspection at the HLO graph and MLIR levels, visualization of Low-Level Operation (LLO) dynamic execution traces, microsecond-level performance counter sampling on TPU v7 (Ironwood), and introduces an event-triggered sampling mode that allows configuring up to 28 hardware counters per SparseCore.

Google DeepMind Releases Results from Randomized Controlled Trial of AI-Assisted Teaching in Sierra Leone ↗

Google DeepMind reported on a pre-registered randomized controlled trial conducted in Sierra Leone, showing that its Guided Learning (based on Gemini) improved students' math scores by +0.258 standard deviations, equivalent to 1.2–1.7 years of regular learning progress; under teacher-led interventions, students who used it for approximately 12 hours showed progress equivalent to 1.8–2.5 years.

SocioHack: First Benchmark for Reward Hacking in Social Institutions Released ↗

King's College London, Fudan University, and The Alan Turing Institute jointly released the SocioHack benchmark, which includes 72 sandbox environments simulating the reward structures of social institutions, categorized into three types: historical (32), synthetic (20), and fictional (20). RL-trained models reproduced historical vulnerabilities within these environments with a recall rate of 61.25% and a precision rate of 90.85%. The study points out that when social institutions are encoded as reward rule systems, reward hacking is equivalent to hacking the rules governing social operations themselves.

Google Research Releases PHRM, a Passive Heart Health Monitoring System Based on Smartphone Front Cameras ↗

Google Research published a paper in Nature introducing PHRM, a passive heart rate monitoring system. Using front-camera videos captured during users' routine face-unlock interactions, PHRM estimates heart rate (MAPE < 10%) and daily average resting heart rate (MAE < 5 bpm) via a lightweight temporal convolutional network. It achieves wearable-device-level accuracy in both laboratory and real-world settings and covers the full spectrum of skin tones. Concurrently, it releases the largest and most diverse smartphone facial video research dataset to date, along with the pre-trained model PHRM-mini.

ElevenLabs Launches Flows Agent in ElevenCreative ↗

ElevenLabs has launched the Flows Agent within ElevenCreative, a conversational AI assistant integrated into a node-based creative canvas. It supports describing needs in natural language (e.g., "create a podcast intro with custom music and voiceover") and automatically builds and executes multimodal pipelines involving images, video, speech, lip-syncing, and background music. It offers clarifying questions, real-time iterative modifications, an Assist mode to confirm expensive operations, and background execution capabilities.

DharmaOCR Paper: A Direct Preference Optimization Method Using the Model's Own Degraded Outputs as Rejections ↗

Dharma AI and Hugging Face collaborated to release the DharmaOCR study, proposing a method that uses the model's own degraded text outputs (such as repetition loops) generated after Supervised Fine-Tuning (SFT) as rejected samples to construct DPO training pairs for structured OCR tasks. This approach reduced degradation rates by an average of 59.4% across 5 open-source model families, reaching up to 87.6%, without compromising extraction quality. The paper indicates that DPO effectiveness requires three structural conditions: failure modes must be clearly classifiable, distinguishable by automated scoring mechanisms, and have sufficient output volume.
