MemCtrl: Teaching Small Models What *Not* to Remember

MemCtrl: Teaching Small Models What Not to Remember A robot assistant walks through a room. It sees a chair from the front. Then from the side. Then from a slightly worse angle. Then the same chair again, because the camera moved while the robot hesitated. In theory, all of this is “context.” In practice, it is mostly noise wearing a productivity badge. ...

Sequential Beats Parallel: When Deep Research Agents Learn to Reflect

A research request usually begins with a deceptively harmless sentence: “Can you give me the full picture?” Then comes the usual enterprise ritual. Someone breaks the topic into pieces. One person checks competitors. Another checks regulation. Another reads technical reports. Another searches recent news. Everyone works quickly. Everyone returns with fragments. Then one unlucky analyst stitches the fragments into a report and pretends the seams are a design choice. ...

CAR-bench: When Agents Don’t Know What They Don’t Know

A car assistant sounds simple until it touches the car. “Turn on the fan.” “Open the sunroof.” “Change my destination to Barcelona.” “Send an email before I arrive.” None of these requests looks philosophically difficult. They are not graduate-level math problems. They do not require poetic reasoning, legal interpretation, or a 128k-token context window stuffed with PDFs. They require the assistant to do something much less glamorous: check the state of the world, follow a few policies, use the right tools, and avoid pretending when something is missing. ...

Optimizing Agentic Workflows: When Agents Learn to Stop Thinking So Much

The most expensive sentence in agentic AI is “Let me think” Every enterprise agent has a little theatre inside it. A user asks for something routine: find a customer record, check a document, submit a form, update a profile, send a message. The agent pauses, reasons, chooses a tool, receives an observation, reasons again, chooses another tool, receives another observation, and continues until the task is finished or the budget is quietly set on fire. ...

When Rewards Learn to Think: Teaching Agents *How* They’re Wrong

An agent fails a task. It searched the web twice, opened the wrong page, trusted a noisy snippet, wrote a plausible final answer, and lost the point. Traditional reinforcement learning sees one thing: wrong. That is brutally clean, and also rather unhelpful. The agent may have performed three useful steps before collapsing at the fourth. Or it may have wandered confidently through nonsense from the beginning. Sparse final-answer rewards flatten these cases into the same training signal. The scoreboard says “0.” Very educational, in the same way a fire alarm teaches architecture. ...

World Models Meet the Office From Hell

Office software has a special talent: it says “success” at the exact moment something has gone wrong somewhere else. A ticket is updated. A role is assigned. An asset is transferred. The API returns a cheerful confirmation. The agent, bless its silicon heart, declares victory. Then a background workflow fires. A user’s clearance changes. Another workflow reacts to that clearance change. A different record is silently updated. A constraint is now violated. The agent does not notice, because the agent saw the office equivalent of a green checkmark and mistook it for reality. ...

Learning to Discover at Test Time: When Search Learns Back

A leaderboard usually treats an AI model like a very fast intern: give it a problem, let it try many times, keep the best answer, and politely ignore the graveyard of failed attempts. That is useful. It is also a little strange. A human engineer does not merely try 25,600 variations of a GPU kernel while keeping the same brain. After the first few failures, she learns which bottlenecks matter. After a lucky partial success, she changes how she thinks about the problem. After enough attempts, the search process is no longer just sampling. It has become learning. ...

Skeletons in the Proof Closet: When Lean Provers Need Hints, Not More Compute

Compute is a very convenient alibi. When an AI system fails, the modern reflex is to ask for more of it: more samples, more tokens, more search, more GPUs, more patience from whoever is paying the invoice. This habit is not always wrong. Sometimes the model really does need another attempt. Sometimes the winning answer is hiding in sample number 47. ...

From Talking to Living: Why AI Needs Human Simulation Computation

The chatbot that cannot check the door A useful AI assistant can write an email, summarize a meeting, explain a regulation, or generate a plan for fixing a server problem. Then something inconvenient happens: the real world disagrees. The meeting transcript missed one speaker. The regulation changed in one jurisdiction. The server error was not caused by the code but by two services fighting over the same port. The customer sounded satisfied in the chat log but cancelled the contract two days later. The model can still talk. Beautifully, even. But it cannot always live inside the situation long enough to notice that its first answer has become stale, incomplete, or simply wrong. ...

Lost Without a Map: Why Intelligence Is Really About Navigation

Lost Without a Map: Why Intelligence Is Really About Navigation Map. That is the word most AI product teams should probably put above their dashboards, agent logs, evaluation suites, and occasionally their office coffee machine. Not because maps are poetic. Because when an AI system fails in a live workflow, the failure often does not look like “the model forgot a fact.” It looks like the system was navigating the wrong space. ...
