Microsoft Research has unveiled SkillOpt, a new method for optimizing AI agent skills without changing model weights. SkillOpt treats skills as trainable parameters, turning skill editing into a controlled optimization process. This approach has shown consistent performance improvements across multiple benchmarks and models, indicating that optimized skills capture reusable knowledge. The ability to transfer these skills across different models and tasks suggests a significant advancement in creating adaptable AI agents.

© MIT Technology Review AIAnthropic has introduced a novel technique to peer into the inner workings of large language models (LLMs) with their new tool, the Jacobian lens, revealing a hidden area called J-space. This space provides insights into the words and concepts an LLM like Claude Opus 4.6 might consider before generating a response. By monitoring this J-space, Anthropic aims to better understand and control model behavior, offering a glimpse into the decision-making processes of LLMs. While not foolproof, this approach marks a significant step in mechanistic interpretability, potentially enhancing model transparency and reliability.
© MIT News AIMIT's FloatForm project introduces a swarm of small robotic boats capable of assembling into larger structures on water, offering a glimpse into a future where floating infrastructure is adaptive and responsive. These robots, each the size of a dinner plate, can autonomously form bridges, platforms, and other structures, potentially transforming urban waterfronts into programmable spaces. Inspired by the self-organizing behavior of fire ants, the system minimizes central control, allowing the robots to coordinate locally and move collectively. This innovation could revolutionize how cities utilize water spaces, providing flexible solutions for mobility, emergency response, and public space expansion.
OpenAI's recent analysis raises questions about the reliability of SWE-Bench Pro, a popular coding benchmark used to evaluate AI models. The findings suggest that there may be inaccuracies in how AI coding capabilities are currently assessed, which could misrepresent the performance of AI systems. This revelation points to the necessity for more robust and precise benchmarking tools within the AI development community. As a result, there may be a push to reevaluate existing benchmarks and enhance the methods used to test and validate AI models.
