Berkeley Introduces GRASP for Robust Planning with World Models
In brief
- Berkeley's BAIR lab has developed GRASP, a new method for gradient-based planning using learned world models.
- This breakthrough addresses the challenges of long-horizon planning, making it more practical and robust.
- Unlike traditional approaches, GRASP lifts trajectories into virtual states, allowing parallel optimization across time and adding stochasticity for better exploration.
- It reshapes gradients to avoid brittle state-input issues, especially in high-dimensional vision tasks.
- The significance lies in its ability to handle large, learned world models that predict future observations effectively.
- While these models are powerful, using them for control or planning has been fragile due to optimization instability and high-dimensional failures.
- GRASP makes gradient-based planning more robust by addressing these technical hurdles, paving the way for more reliable applications across robotics and autonomous systems.
- Looking ahead, researchers will focus on integrating GRASP into real-world systems and exploring its potential in complex environments with dynamic uncertainties.
- This advancement could lead to more efficient and effective control strategies in various industries relying on advanced planning and decision-making.

AI Must Respect Indigenous Knowledges
Researchers partnered with the Amah Mutsun Tribal Band to record native plant knowledge. This project aims to preserve Indigenous Knowledge and language. The concern is that artificial intelligence will become another extractive force that takes Indigenous Knowledges without consent. Our research found that AI can entrench existing biases and harm communities. However, AI can also be a tool to preserve knowledge and design solutions for community benefit. AI can help revitalize endangered languages and document oral traditions. Researchers are using AI to map culturally significant land and identify wildflowers. Next, AI developers will work to build technology that respects Indigenous Knowledges.
New Model Predicts Cancer Treatment Response
Scientists created a new model to predict how cancer patients respond to a type of treatment. The model is called COMPASS. It looks at the genes in a tumor to make predictions. The COMPASS model is better at making predictions than other methods. It was tested on 10,184 tumors from 33 types of cancer. The model improved accuracy by 8.5 percent. This matters because it can help doctors choose the right treatment for each patient. The model can also help patients live longer. Patients who were predicted to respond to the treatment did live longer. Next, the model will be used to design new trials and studies to help more patients.
11 Language Models Compared on Code Reorganization Task
A recent experiment compared 11 language models on a code reorganization task. The models were asked to propose how to untangle a complex node in a LangGraph agent. This matters because the node had 350 lines of logic, making it hard to explain, debug, and test. The results will help developers decide which model to use for generating and evaluating code proposals.
AI Helps Identify At-Risk Teens
Researchers are using AI to help doctors identify teens at risk of mental health crises. More than 40 percent of high school students feel persistently sad or hopeless. Nearly one in five teens seriously consider suicide. The AI model analyzes data from over 11 thousand children, including family conflict and health data. It can identify at-risk teens with 75 percent accuracy, up to a year before symptoms appear. This tool could help doctors spot trouble early and change lives. The Duke research team is now testing the AI tool in clinics to see how well it works outside the lab. The AI tool will be used to automate the process and analyze data in real-time, flagging which teens may be at risk during a routine checkup. Doctors will use this tool to help teens sooner.
Students Show Low 'Epistemic AI Literacy' When Using Generative AI for Coding
A new study reveals that most students lack "epistemic AI literacy" when using generative AI tools for programming. Researchers analyzed over 10,000 interactions between students and AI systems during coding tasks. They found that 78.8% of these interactions relied on non-mastery-oriented goals, with students often outsourcing work or seeking simple explanations rather than deeply understanding the AI's processes. The study highlights a significant gap in how students engage with generative AI. Only 11.1% demonstrated high epistemic engagement, combining mastery goals with advanced strategies like justifying their reasoning and carefully monitoring prompts. This suggests that most students are not effectively developing the critical thinking skills needed to work alongside AI systems. Looking ahead, educators will need to focus on teaching these advanced epistemic strategies to better prepare students for collaboration with generative AI tools in programming and other fields.
