Agents

TL;DR Deep Research agents are great at planning over messy data but bad at disciplined execution. Semantic-operator systems are the opposite: they execute efficiently but lack dynamic, cross-file reasoning. The Palimpzest prototype bridges the two with Context, compute/search operators, and materialized context reuse—a credible blueprint for an AI‑native analytics runtime over unstructured data. The Business Problem: Unstructured Data ≠ SQL Most companies still funnel PDFs, emails, HTML, and CSVs into brittle ETL or costly human review. Classic OLAP/SaaS BI stacks excel at structured aggregates, but stumble when a question spans dozens of noisy files (e.g., “What’s the 2024 vs 2001 identity‑theft ratio?”) or requires nuanced judgments (e.g., “Which Enron emails contain firsthand discussion of Raptor?”). Two current approaches each miss: ...

TL;DR Pair a classic mixed‑integer inventory redistribution model with an LLM-driven context layer and you get explainable optimization: the math still finds near‑optimal transfers, while the LLM translates them into role‑aware narratives, KPIs, and visuals. The result is faster buy‑in, fewer “why this plan?” debates, and tighter execution. Why this paper matters for operators Most planners don’t read constraint matrices. They read stockout risks, truck rolls, and WOS. The study demonstrates a working system where: ...

TL;DR — A new framework (EconAgentic) models DePIN growth stages, token/agent interactions, and macro goals (efficiency, inclusion, stability). Its key finding: more patient LLM agents (i.e., slower to exit) can increase inclusion and stability with little efficiency penalty. Sensible—but only if token price formation, data integrity, and geospatial participation are measured rigorously. Why this paper matters DePIN (Decentralized Physical Infrastructure Networks) turns physical capacity—wireless hotspots, sensors, compute, even energy—into token‑incentivized networks. The promise is Uber/Airbnb’s distribution without the platform as rent‑extractor. EconAgentic contributes a general model that: ...

Large models are passing tests, but they’re not yet passing life. A new paper proposes Experience‑driven Lifelong Learning (ELL) and introduces StuLife, a collegiate “life sim” that forces agents to remember, reuse, and self‑start across weeks of interdependent tasks. The punchline: today’s best models stumble, not because they’re too small, but because they don’t live with their own memories, skills, and goals. Why this matters now Enterprise buyers don’t want parlor tricks; they want agents that schedule, follow through, and improve. The current stack—stateless calls, long prompts—fakes continuity. ELL reframes the problem: build agents that accumulate experience, organize it as memory + skills, and act proactively when the clock or context demands it. This aligns with what we’ve seen in real deployments: token context ≠ memory; chain‑of‑thought ≠ skill; cron jobs ≠ initiative. ...

The pitch: a unified plug—and a tougher test The Model Context Protocol (MCP) is often described as the “USB‑C of AI tools”: one standardized way for agents to talk to external services (maps, finance data, browsers, repos, etc.). MCP‑Universe, a new benchmark from Salesforce AI Research, finally stress‑tests that idea with real MCP servers rather than toy mocks. It derives success from execution outcomes, not multiple‑choice guesswork—exactly what enterprises need to trust automation. ...

TL;DR Today’s long-context and RAG systems scale storage, not thinking. Cognitive Workspace (CW) reframes memory as an active, metacognitive process: curate, plan, reuse, and consolidate. In tests, CW reports ~55–60% memory reuse and 17–18% net efficiency gains despite a 3.3× operation overhead—precisely because it thinks about what to remember and why. The Setup: Context ≠ Cognition Over the past 18 months we’ve cheered >1M-token windows and slicker attention kernels. But piling tokens into a context is like dumping files on a desk; it’s storage without stewardship. In knowledge work, what moves the needle is not how much you can “see” but how well you organize, recall, and reuse—with intent. ...

What if the AI didn’t just answer a question—it ordered the right tests, asked for the right observations, and stopped when it had enough to call the case? A new paper introduces DxDirector-7B, a 7B-parameter medical LLM trained to act as the director of care, not the assistant. Instead of waiting for a physician to assemble clean inputs, the model starts from the patient’s vague chief complaint (e.g., “tummy pain and tired”) and then plans the diagnostic pathway, requesting only those clinician actions that software cannot perform (physical exams, labs, imaging). The goal is twofold: maximize diagnostic accuracy and minimize human workload. ...

In the AI race to make large language models both factual and reasoned, two camps have emerged: one focused on retrieval-augmented generation (RAG) to fight hallucination, the other on long-chain reasoning to mimic logic. But neither wins alone. This week’s survey by Li et al. (2025), Towards Agentic RAG with Deep Reasoning, delivers the most comprehensive synthesis yet of the field’s convergence point: synergized RAG–Reasoning. It’s no longer a question of whether retrieval helps generation or reasoning helps retrieval—but how tightly the two can co-evolve, often under the coordination of autonomous agents. ...

The financial industry has always prided itself on cold precision. For decades, quantitative models and spreadsheets dominated boardrooms and trading desks. But that orthodoxy is now under siege. Not from another statistical breakthrough, but from something surprisingly human-like: Large Language Models (LLMs). Recent research shows a dramatic shift in how AI—particularly LLMs like GPT-4 and LLaMA—is being integrated across financial workflows. Far from just summarizing news or answering earnings call questions, LLMs are now organizing entire investment pipelines, fine-tuning themselves on proprietary data, and even collaborating as autonomous financial agents. A recent survey by Mahdavi et al. (2025) categorized over 70 state-of-the-art systems into four distinct architectural frameworks, offering us a lens through which to assess the future of financial AI. ...
