    What AI gets wrong and what failure teaches us

    In a Microsoft Research Podcast conversation with Chad Atalla, Microsoft partner research manager Jennifer Neville discusses how her team uses practical evaluations—multiturn conversations, collaborative environments and long-horizon agentic tasks—to find where current AI systems break down beyond traditional benchmarks. She describes research showing that model performance degrades significantly over multiturn interactions and that errors can accumulate in long workflows, and offers practical guidance such as restarting a chat with a fully specified single turn and checking answers rather than fully delegating work.

    Unlocking Earth AI’s planetary geospatial foundation models for global public health

    Google researchers describe using the Population Dynamics Foundation Model (PDFM), part of Google Earth AI, to turn privacy-preserving search trends, mobility, built-environment and environmental data into monthly location embeddings that can be plugged into existing epidemiological models without task-specific fine-tuning. Independent partner evaluations across five public health challenges — MMR vaccination at the US–Canada border, US cardiovascular disease nowcasting, dengue forecasting in Mexico, postpartum depression risk prediction, and cholera emergence in the DRC — reported matched or improved performance over conventional inputs. The authors note current limitations such as static snapshots and say PDFM embeddings are available in Preview as Population Dynamics Insights, with no-cost access for select academic and public health research.

    Open and Emergent Problems in Agentic Privacy and Security: A Contextual Angle

    Google shares a new workshop report, produced with more than 50 academic and industry leaders at the Contextual Agent Privacy and Security (CAPS) Workshop held in late 2025 in New York City, on foundational privacy and security challenges facing autonomous agents. The report grounds agent privacy and security in the theory of Contextual Integrity, extending it to contextual security, and advocates a contextual policy engine within a supervisor layer alongside system-level sandboxing, model-level reasoning, user-centric controls, multi-agent guardrails, and ecosystem governance. It also calls for standardized multi-agent benchmarks and "Agent Gym" sandboxes, and invites the broader research community to collaborate.

    AI is changing developer work. Here are three skills to strengthen.

    GitHub outlines three skills developers should strengthen as AI reshapes their work: learning to direct AI agents rather than just use them, not trusting AI's first answer and instead having a second model critique it before review, and using time saved on implementation to tackle broader problems like customer needs and architectural tradeoffs. The post illustrates these with examples such as coordinating multiple agents on an authentication flow and a second model critiquing a SQL query. It notes GitHub Copilot's built-in Rubber Duck agent uses a second model to critique plans, code, and tests.

    Forecasting space weather risks on power grids

    A Microsoft Research intern developed a machine learning pipeline that uses forecast-time solar-wind data, AE and Dst index forecasts, local geology and grid data to produce location-specific geomagnetically induced current risk estimates for 66,935 substations in the continental United States, 30 to 60 minutes ahead. During the 2020-2026 evaluation period the pipeline detected nearly 80% of major space-weather events, with detection rates of 76.5% for events ≥10 nT/min, 81.2% for ≥20 nT/min and 64.1% for ≥50 nT/min, and it produced estimates for all substations in about 333 milliseconds. The authors note that further validation with utilities and operational data would be needed before use in grid operations.

    GitHub Copilot app for Beginners: How to build custom workflows with canvases

    GitHub explains canvases in the GitHub Copilot app: customizable, bidirectional interfaces such as kanban boards, checklists, or dashboards that you create by entering the /create-canvas skill in an agent session and describing the workflow in plain English. The agent builds the interface in the right-side panel, and both you and the agent can update its shared state immediately without a separate sync step. Canvases are saved as extensions for reuse or team sharing, and ready-made ones are available through Awesome Copilot.

    Modernizing complex legacy code with AI agents.

    Mistral helped a European energy operator migrate 40,000 lines of Fortran 77 to C++ for a physics-intensive reservoir simulator that had no test suite or centralized documentation. The team built a numerical parity harness before migrating, used agents to document the codebase via a caller-callee tree, and settled on a human-supervised workflow of coder, tester and reviewer agents migrating module by module. The first sprint covered 40,000 of 300,000 lines, and the authors note that migrations depending on external systems or undocumented physics would face additional challenges.

    From CUDA to MLX: How K-Search Brings Decades of Kernel Expertise to Apple Silicon

    IBM Research extended K-Search, an evolutionary LLM-driven kernel search framework from UC Berkeley Sky Lab, with a native MLX backend and a structured CUDA-to-MLX translation layer that maps CUDA primitives, constraints and optimization patterns onto Apple Silicon equivalents. On Apple Silicon the approach reached 0.97x the speed of the native MLX Attention kernel and up to a 20x prefill speedup over the community mlx-lm implementation on the Mamba SSM kernel, attributed largely to adding a parallel scan. The authors say the bottleneck was not the LLM's ability to write Metal code but the quality of context and constraints supplied to it.

    Why it matters: Describes a concrete method for transferring CUDA kernel expertise to non-NVIDIA hardware, with reported benchmark numbers and an open-source reproduction path.

    Teaching LLMs to Update Beliefs for Efficient Long-Horizon Interaction

    The post introduces ABBEL, a framework that replaces full interaction history with periodically updated natural-language "belief states" and supervises their contents through belief grading, including an autoencoding-inspired reconstruction objective. On CollabBench collaborative coding, reconstruction-based belief grading roughly halved the gap to full-context models and trained in 50 steps instead of 100, while using fewer peak tokens; on Combination Lock and multi-objective QA, domain-knowledge grading and a peak belief length penalty further improved efficiency. The authors argue that isolating and supervising summaries addresses the performance cost of recursive summarization in long-horizon tasks.

    Intelligence is Free, Now What? Data Systems for, of, and by Agents

    A Berkeley EPIC Data Lab perspective argues that as inference costs fall toward near-zero, data systems face three challenges: redesigning for agent workloads (e.g., exploiting the 80-90% duplicate sub-queries in agentic speculation), building a substrate for agent swarms (structured memory, concurrent shared-state edits, coordination), and letting agents synthesize custom data systems that can be trusted. It surveys work including Bespoke OLAP, GenDB, and custom key-value store synthesis, and sketches a future where agents and data systems co-evolve and blur together.

    Adaptive Parallel Reasoning: The Next Paradigm in Efficient Inference Scaling

    This post surveys parallel reasoning methods for LLMs, contrasting fixed approaches like self-consistency, Best-of-N, and tree search with adaptive parallel reasoning (APR), where the model itself decides when to parallelize, how many threads to spawn, and how to coordinate them. It describes fork-join inference designs, including engine-modifying KV cache stitching (Multiverse) versus client-side orchestration (ThreadWeaver), and covers training via SFT demonstrations and RL rewards based on critical-path efficiency gated by correctness. It closes with evaluation differences across Multiverse, ThreadWeaver, NPR, and Parallel-R1, plus open questions on stability and whether parallelization mainly helps as a training-time exploration scaffold.

    Gradient-based Planning for World Models at Longer Horizons

    The post introduces GRASP (Gradient Relaxed Stochastic Planner), a gradient-based planner for learned world models that lifts trajectories into virtual states for parallel-in-time optimization, adds Gaussian noise to state iterates for exploration, and stops brittle state-input gradients through the model while retaining action gradients. It argues that long-horizon planning with modern world models is fragile due to ill-conditioned rollouts, non-greedy local minima, and adversarial-robustness-style sensitivity of state Jacobians, and reports Push-T results where GRASP outperforms CEM, GD, and LatCo at horizons from 40 to 80. The work is by Michael Psenka with Mike Rabbat, Aditi Krishnapriyan, Yann LeCun, and Amir Bar (arXiv 2602.00475).

    Identifying Interactions at Scale for LLMs

    This blog post introduces SPEX and ProxySPEX, algorithms that use strategically selected ablations and sparse recovery from signal processing and coding theory to identify influential feature, data, and model-component interactions at scales far beyond prior methods, with ProxySPEX exploiting hierarchy to match SPEX using roughly 10x fewer ablations. The authors demonstrate the framework on sentiment analysis, a modified trolley problem with GPT-4o mini, CIFAR-10 data attribution with ResNet, and attention head pruning on MMLU, where a ProxySPEX-informed pruning strategy improved target-task performance. Code for both algorithms is available in the SHAP-IQ repository.

    Information-Driven Design of Imaging Systems

    Researchers present a framework that estimates mutual information directly from noisy measurements using a known noise model and a learned model of measurement variation, enabling direct evaluation and optimization of imaging systems by information content. In their NeurIPS 2025 paper, information estimates predicted decoder performance across color photography, radio astronomy, lensless imaging, and microscopy, and their IDEAL method optimized encoder parameters via gradient ascent, matching end-to-end optimization on color filter design without requiring a decoder network. The authors suggest the approach could extend to other sensing domains modeled as deterministic encoding with known noise characteristics.
