Prem Natarajan, a former Amazon Alexa AI leader, became Chief Scientist at Capital One to advance AI research tailored to banking's complex constraints rather than deploying off-the-shelf models. Capital One filed 38 percent of AI patents among the top 50 financial institutions and was recognized as the only bank among top U.S. patent leaders in agentic and generative AI in 2025. The bank is developing domain-specific AI systems like fully agentic customer service tools and fraud detection across billions of transactions, requiring original research that adapts general models to real-world financial problems serving over 100 million customers.

Microsoft Research and collaborators developed generative causal testing (GCT), a method that distills opaque language model predictions of brain activity into readable explanations by having LLMs generate targeted stories to confirm which concepts specific brain regions respond to. The approach was published in Nature Neuroscience and successfully identified known selectivity patterns, separated three place-processing regions previously thought similar, and discovered unmapped prefrontal micro-regions tuned to specific concepts like dialogue and clock times. GCT demonstrates that black-box predictive models can be converted into testable scientific hypotheses that can be verified through real experiments.

Anthropic introduced Claude Tag, enabling users to mention and delegate tasks to a shared instance of Claude Code within Slack while maintaining conversation context. The feature allows Claude Code to access Slack messages and manage workflows without losing context from previous discussions. This change enables team-based agent collaboration and task delegation through Slack's interface.

AI systems have progressed from basic mathematical computation to solving unsolved problems and producing publishable research, with Google DeepMind's Aletheia achieving Ph.D.-level results and OpenAI's system disproving a conjecture in combinatorial geometry. Large language models combined with proof assistants are automating the formalization of mathematical proofs, removing a bottleneck that previously required mathematicians to manually translate informal proofs into machine-readable code. As AI increasingly handles mathematical problem-solving, mathematicians must reconsider whether their value lies primarily in obtaining answers or in the deeper satisfaction found in the struggle to understand complex ideas.

Researchers released a report measuring the generative AI economy at $110 billion in revenue over the past 12 months with an annualized run rate of $175 billion, using a deduplicated model that tracks end-customer spending rather than double-counting supply chain flows. The analysis found that AI revenues are growing roughly three times faster than previous technology waves like mobile and internet, and that hyperscaler revenues are approximately covering depreciation expenses on AI infrastructure capital spending. As token prices fall, demand elasticity shows a 10% price cut generates 12-18% more token usage, suggesting the market will expand further as models improve and become cheaper.

Alibaba's Qwen team released three new robotics models—Qwen-RobotNav, Qwen-RobotManip, and Qwen-RobotWorld—designed to translate visual understanding into robotic actions. The models address the gap between perception and physical execution, with the main bottleneck identified as converting visual understanding into motor commands rather than general intelligence. This shift enables Qwen's language models to move beyond text and image tasks into controlling physical robotic systems.

Google researchers developed linear elastic caching that dynamically adjusts cache size using lightweight machine learning to optimize the trade-off between memory costs and cache misses. In production testing on Spanner, the approach reduced memory usage by 15.5% and total cost of ownership by approximately 5% while increasing cache misses by only 5.5%. The system frames cache eviction as a ski rental problem where data can be kept in expensive RAM or evicted to slower storage, with a shallow decision tree predicting optimal retention times for each data page.

IBM announced 0.7 nanometer transistor chips, the smallest in the world, using a new three-dimensional nanostack architecture with innovations in wafer bonding and memory scaling. The chips are 70% more efficient than IBM's previous 2 nanometer chips from 2021, and could theoretically enable AI accelerators to deliver 9,000 TOPS compared to current accelerators' 1,500 TOPS, potentially reducing training time for large language models from three months to two weeks. The nanostack design could support a decade of further chip innovations by stacking transistors vertically rather than only shrinking them horizontally.

Researchers compared Olmo 3 (a transformer) and Olmo Hybrid (a hybrid architecture) by analyzing how well each predicted different token types, finding that hybrid models excel at predicting content words like nouns and verbs with a loss gap of 0.04 compared to 0.02 on function words, while transformers maintain their advantage on tokens that repeat verbatim from earlier in the passage. The study used regression analysis across passages of prose, code, and structured text to isolate architecture-specific strengths. This fine-grained token-level analysis suggests that hybrid architectures warrant further development and that single overall loss metrics are insufficient for comparing different model architectures.

OpenAI's research paper documents how AI agents are handling longer and more complex tasks, expanding their application across different work roles. The paper demonstrates agents completing multi-step processes that previously required sustained human attention and decision-making. Organizations can now delegate more intricate workflows to AI systems, reducing manual intervention in routine and complex work alike.
