CHINA EXPANDS TRAVEL CURBS TO TOP AI TALENT AT PRIVATE FIRMS

China has restricted overseas travel for top AI professionals in private firms. These individuals will need approval from relevant authorities before embarking on overseas travel. The restricted individuals include a mix of startup founders, researchers, and executives. China has previously restricted travel for key personnel, from prominent researchers to nuclear scientists and executives at state firms, but it is unusual for the travel restrictions to be extended to private firms.

HOW WE CONTAIN CLAUDE ACROSS PRODUCTS

Agents are a new category of software, but their system-level interactions are not. Design for containment at the environment layer first, then steer behavior at the model layer. Match isolation strength to the user's capacity for oversight, and use battle-tested components. AI deployment can be risky, but placing a hard limit on the potential damage often shifts the balance in the right direction.

EXTRACT MORE KERNEL PERFORMANCE WITH NVIDIA COMPILEIQ AUTO-TUNING

NVIDIA's CompileIQ, integrated into CUDA 13.3, uses AI-driven evolutionary algorithms to auto-tune GPU compiler settings, optimizing performance for specific workloads beyond standard heuristics. It provides fine-tuned compiler configurations for individual kernels, offering up to 15% performance improvements on already-optimized AI inference and training tasks. With CompileIQ, developers define optimization objectives, allowing for multi-objective tuning, including trade-offs between runtime, power, and compile time, making it suitable for high-impact applications like LLM inference.

DEEPSWE

DeepSWE introduces a sophisticated benchmark for long-horizon software engineering, with tasks spanning 91 repositories in 5 languages and ensuring no model has pre-seen the solution. It delivers four key improvements: tasks are contamination-free, reflect real-world complexity, cover diverse repositories, and employ reliable verification processes. DeepSWE provides sharper separation metrics for coding agents, contrasting with the clustering seen in existing benchmarks like SWE-Bench Pro.

SPACEX HAS TWO AI COMPUTE STORIES; ONLY ONE GENERATES REVENUE

SpaceX's S-1 tells two stories. The first is that the company is spending billions building terrestrial data centers and has signed one disclosed external customer, Anthropic, with a deal worth $1.25 billion per month through to May 2029. The second is that the future of AI inference belongs in orbit and that SpaceX is the only company that has already accomplished the key technical challenges associated with evolving connectivity satellites into AI compute satellites. Both stories are presented with conviction, and neither is contingent on the other being wrong.

INITIAL RESULTS ON LEGAL AGENT BENCHMARK

Harvey baselined frontier models on its Legal Agent Benchmark holdout under an "all-pass" standard requiring every rubric criterion to pass, and Claude Opus 4.7 led at just 7.1% with Sonnet 4.6 at 5.4%, Opus 4.6 at 4.2%, GPT-5.5 at 2.1%, and Gemini 3.5 Flash at 0.8%, signaling legal work is far from saturated by frontier intelligence.
