Lean LLMs, Heavy Lifting: When Workflows Beat Bigger Models

Seats are not just seats. For an airline, a seat can be sold as a cheap restricted fare, a flexible economy fare, or not sold at all. A passenger who cannot buy one fare may upgrade, switch flights, or disappear into a competitor’s booking funnel. Multiply that across routes, departure times, fare classes, demand segments, aircraft capacity, and network balance rules, and the innocent phrase “optimize ticket sales” becomes a fairly effective trap for language models. ...

Think Before You Sink: Streaming Hallucinations in Long Reasoning

A bad answer is easy to audit. It sits there, smug and wrong. A bad reasoning process is worse. It looks useful while it is drifting. It explains itself. It produces intermediate steps that sound locally plausible. It may even correct one mistake while preserving another, like a spreadsheet with a broken formula hiding behind tasteful formatting. ...

Talking to Yourself, but Make It Useful: Intrinsic Self‑Critique in LLM Planning

“Please double-check your work” is one of the least expensive quality-control systems ever invented. It is also one of the least dependable. A person who overlooked a constraint the first time may overlook it again. A language model is no different, except that it can produce a longer and more persuasive explanation of why the overlooked constraint was never important. ...

SpatialBench: When AI Meets Messy Biology

A dataset arrives. Not a clean demo dataset. Not a tidy CSV with three columns and a tutorial notebook waiting nearby like a hotel concierge. A real spatial biology dataset arrives: high-dimensional, platform-specific, noisy, partially processed, full of tacit assumptions, and attached to a scientific question that cannot be answered by knowing biology in the abstract. ...

When Actions Need Nuance: Learning to Act Precisely Only When It Matters

A warehouse robot does not always need elegance. In an open aisle, “move forward a bit” is probably good enough. Near a shelf, a wall, or a human ankle, “a bit” becomes an expensive philosophy. That is the practical problem behind Context-Sensitive Abstractions for Reinforcement Learning with Parameterized Actions, the paper introducing PEARL: Parameterized Extended state/action Abstractions for Reinforcement Learning.1 The paper is not really about making reinforcement learning more fashionable. Mercifully. It is about making action precision conditional. ...

AGI by Committee: Why the First General Intelligence Won’t Arrive Alone

The meeting room is already becoming the machine Meeting rooms are underrated metaphors for intelligence. A company can produce a market forecast, negotiate a contract, audit a supplier, design a campaign, and respond to a legal dispute without any single employee understanding the whole operation. The intelligence is distributed. One person knows finance. Another knows regulation. Someone else knows the client. A manager routes the work. A spreadsheet remembers what everyone forgot. Somehow, the organization acts. ...

Delegating to the Almost-Aligned: When Misaligned AI Is Still the Rational Choice

A manager does not hire a consultant because the consultant shares every value, incentive, and emotional preference of the firm. The consultant wants fees. The doctor wants throughput. The lawyer wants billable hours. The cloud provider wants usage. Humanity, somehow, survives this scandal. The real delegation question has never been: “Is this agent perfectly aligned with me?” It is: “Will things go better if I let this agent decide here?” ...

Ports, But Make Them Agentic: When LLMs Start Running the Yard

Ports are already full of automation. Cranes move containers, AGVs follow routes, software coordinates flows, dashboards blink reassuringly at managers who are paid to pretend that blinking equals control. Then one terminal changes its layout, closes a road, adds a vehicle restriction, or introduces a new safety corridor. Suddenly the “automated” dispatching system needs engineers, operations researchers, domain experts, test scripts, model reformulation, solver debugging, and several meetings where everyone discovers that “just adjust the rule” was not, in fact, just. ...

Bits, Bets, and Budgets: When Agents Should Walk Away

Budget is not an afterthought Budget is usually treated as the boring part of agent design. The exciting part is the agent: planning, calling tools, trying strategies, revising itself, and occasionally behaving like a junior analyst who has discovered both confidence and the corporate credit card. But in real automation, budget is not boring. Budget is the boundary between useful autonomy and expensive wandering. ...

Breaking Rules, Not Systems: How Penalties Make Autonomous Agents Behave

Emergency is a terrible product requirement. It sounds simple in a meeting: “The agent should follow policy, except when the situation is urgent.” Wonderful. Very human. Also almost useless. A delivery robot should not enter a restricted zone. Unless the package is critical medicine. A warehouse agent should not skip safety checks. Unless a fire alarm requires rerouting. A self-driving system should obey traffic norms. Unless an emergency trip makes delay costly. But “unless urgent” does not tell the agent which rule can bend, which rule must hold, and which shortcut turns the system from flexible into reckless. ...
