HiFi-UMI: Learning Deployable Manipulation Policies from High-Fidelity UMI Data Alone
Simple AI (Simple World Lab)HiFi-UMI is a portable, robot-free data-collection rig (head-mounted stereo-inertial SLAM plus synchronized wide-FoV cameras) that raises the fidelity of Universal Manipulation Interface demonstrations enough that policies trained solely on this data deploy directly to real robots, matching in-domain teleoperation across three VLA backbones. The team open-sourced HiFi-UMI-2K, 2,000 hours of microsecond-synchronized demonstrations.

1,100+ Employees at OpenAI, Anthropic, Google, and Meta Sign "Pacing the Frontier" Letter
More than 1,100 employees across OpenAI, Anthropic, Google, and Meta — including Dario Amodei, OpenAI chief scientist Jakub Pachocki, and Google's Anca Dragan — published "Pacing the Frontier," asking the US government to help build international technical and governance tools for a coordinated, verifiable slowdown of automated AI development. OpenAI and Anthropic subsequently endorsed the statement as companies.
Yandex launches "75/75/75" program to push AI-native software development
YandexYandex announced the "75/75/75" initiative: by the end of 2026 it wants at least 75% of its engineers regularly using AI to write code, AI involved in preparing at least 75% of code changes company-wide, and each such change to be at least 75% AI-generated. The push leans on Yandex's internal coding agent GENA, already connected to over a thousand projects, and cites cases like an ~80% AI-generated video-translation rewrite finished in two days instead of two to three weeks.
Google DeepMind Disbands Dedicated AlphaFold Team, Shifts Researchers to Gemini
Google DeepMindThe Financial Times reported on July 29 that Google DeepMind dissolved the dedicated team behind its Nobel Prize-winning AlphaFold protein-structure system over the past year, reassigning most researchers to Gemini and other scientific programs (enzyme design, nuclear fusion, genomics). DeepMind confirmed the personnel moves to press; some AlphaFold co-authors, including lead author John Jumper, have left for Anthropic.
A New Role for Relevance: Guiding Corpus Interaction in Agentic Search
TencentTencent researchers propose RARG (Relevance-Aware RipGrep Search Agent), which uses relevance scores not just to pick top documents but as an execution prior that orders search, seeds entry points, and reranks excerpts during multi-step corpus interaction. It outperforms existing retrieval and interaction-based search agents on QA and reasoning benchmarks.
HumanCLAW: Can Vision-Language Models Act Through a Body?
Meta ResearchMeta introduces HumanCLAW-Bench, 1,218 long-horizon egocentric find-navigate-interact episodes across 41 indoor scenes, and a framework that separates decision-making from motor execution to isolate a VLM's 'action intelligence.' The best of nine tested state-of-the-art models achieved only 16.8% success, with failures traced to lost embodied self-awareness rather than poor target recognition.

Pass the Baton: Trajectory-Relayed On-Policy Distillation
Zhejiang UniversityA new on-policy distillation method where a teacher and student model relay segments of a reasoning trajectory to each other, aiming to keep the student's training distribution closer to what it will see at inference than standard full-trajectory distillation.
GitHub Copilot CLI 1.0.76 adds sessions sidebar, enterprise sandbox floor
GitHubGitHub Copilot CLI v1.0.76 (July 30, 2026) adds a new Sessions sidebar for managing multiple concurrent sessions, lets enterprise administrators enforce a restrictive sandbox floor that managed settings can tighten but never loosen, adds grok-4.5 model support, enforces sandbox denied-path rules for relative and symlinked entries on macOS/Linux, and caps hook output at 10 MiB to prevent a memory-exhaustion vector from unbounded hook responses.
OpenCode 1.18.6-1.18.9 fixes MCP compatibility and desktop stability
SSTAcross four releases from July 27-28, 2026 (v1.18.6 through v1.18.9), OpenCode restored compatibility with legacy MCP SDK clients, fixed MCP servers failing to reconnect after expired SDK sessions (including under concurrent requests), honored configured MCP OAuth callback ports in mcp debug, and fixed several desktop-app issues including branch-specific repository cache corruption and a Solid.js cleanup crash breaking navigation.
