First, given the rendered web page and the evaluation rubrics, an action planner generates a complete action list in a single pass, specifying the sequence of user interactions needed to exercise the target functionality. Second, a Playwright-based render server executes these actions in a live browser environment and records the resulting interaction trace, including screen recordings and state changes at each step. Third, a judge model evaluates sampled frames from the recordings together with the source code against the rubric criteria, producing the final score.

However, deploying a fully autonomous visual agent loop for judging is impractical under current constraints: multi-turn agent interactions incur high inference cost (He et al., 2026), and sequential decision-making introduces compounding errors that degrade evaluation stability. We therefore design a semi-automated agentic interactive judge that balances interaction coverage with efficiency and reliability.

Based on current trends Europeans could end up putting more fresh equity into American AI and satellite capabilities than European ones this year.

Because the actor and critic operate on this compact representation, they can be represented with small networks that are trained directly on the robot, with hundreds of updates per second. This makes RL training responsive enough to improve the behavior after each attempt.

The training dynamics show why this separation matters. In the single-agent baseline, solve rates quickly saturate to near-perfect performance. This is not evidence of a strong curriculum. It means the proposer has found tasks its own solver can reliably solve. In PopuLoRA, solve rates oscillate instead of monotonically increasing.

End-to-End User Story Execution: I still prefer to define the user stories myself. As an architect, I feel I have a better sense of what I’m building and how I’d like to build it. However, the delivery of a perfect execution is something I believe AI can handle increasingly well. Today, I still have to spend a fair amount of time steering the AI — telling it to continue when it pauses, suggesting refactoring, reviewing test coverage, and suggesting additional tests. I would prefer the AI take more autonomy to drive this end-to-end. Automated Contract Workflows: The flow of applying contracts s…

In my organization, there are no formal job descriptions or organizational charts. Responsibilities are defined in a general way, so that people are not circumscribed. All are permitted to do as they think best and to go to anyone and anywhere for help.

Weaknesses overlooked in oral discussion become painfully obvious on the written page.

I insist they report the problems they have found directly to me—and in plain English. This provides them unlimited flexibility in subject matter—something that often is not accommodated in highly structured management systems—and a way to communicate their problems and recommendations to me without having them filtered through others. The Defense Department, with its excessive layers of management, suffers because those at the top who make decisions are generally isolated from their subordinates, who have the first-hand knowledge.

The man in charge must concern himself with details. If he does not consider them important, neither will his subordinates. Yet “the devil is in the details.” It is hard and monotonous to pay attention to seemingly minor matters. In my work, I probably spend about ninety-nine percent of my time on what others may call petty details.

We still use our mouse to navigate and tell our computers what to do next, but routine actions are typically communicated in form of quick-fire keyboard presses: ⌘b to format text as bold, ⌘t to open a new tab, ⌘c/v to quickly copy things from one place to another, etc.
