A dot is green when the detector's human-likelihood score for that run was 0.50 or higher. The detector rate is the mean of that detector's scores across the runs, the same number the detector pages rank by; it is not the count of green dots, which the Runs passed row shows. Hover a dot for the score.

How to read these scores

Each detector returns a human-likelihood on a common 0 to 1 scale, where 1 means it judged the text human-written and 0 means it flagged it as AI. On these pages a verdict counts as passed when that score is at least 0.50, the midpoint of the detector's own scale. That threshold exists only to draw the chips: the bypass rate on the leaderboard is the mean of each test's scores from the 6 detectors, a continuous number, so a tool's pass count and its bypass rate will not be the same figure.

Communities should not treat public art and infrastructure as automatic rivals. Roads, water systems, sidewalks, and transit keep people safe and connected; public art can make those shared spaces more welcoming, memorable, and representative of the people who use them. The challenge is to fund both without asking residents to choose between a mural and a working water main.

Essential repairs and safety needs should come first. A city should not delay fixing a dangerous bridge to commission a sculpture. But “infrastructure first” need not mean “art never.” Communities can set aside a modest, transparent portion of capital-project budgets for art when projects create public spaces. A transit station, for example, can incorporate locally designed tilework during construction, often more efficiently than adding it later.

Decisions should reflect local priorities, not just the preferences of officials or major donors. Public meetings, accessible surveys, and paid input from neighborhood artists can help identify projects residents value. Budgets should also include maintenance: neglected art, like neglected infrastructure, can become an eyesore and an expense.

Finally, cities should evaluate funding over time. Are basic services improving? Is art reaching underserved neighborhoods? Are projects creating opportunities for local artists and encouraging people to use public spaces? These questions help communities adjust their spending rather than defend a fixed formula.

A sound balance protects essential services while recognizing that a community needs more than functioning pipes and pavement. Public art can strengthen belonging and civic pride, especially when residents help shape it and its costs remain clear.

However, there is no need to assume that communities should consider public art and infrastructure to be opponents of each other. Infrastructure provides security and connection for people. Public art can enhance the feeling of community and represent its identity better. The problem is that communities must provide both infrastructure and art without making people sacrifice one of them.

Obviously, the community should take care of its needs to fix critical issues before investing in art. However, "infrastructure first" does not necessarily imply "art never". In some cases, cities and states may allocate a small amount of the budget to implement art in capital projects of developing public spaces. For example, the construction of the transport station can be combined with installing local tile designs.

The community should determine the list of projects considering local priorities and not only opinions of the officials or major donors. Surveys, open public meetings, paid consultations with neighborhood artists can help to identify valuable projects. In addition, it is important to allocate funds for maintenance because it prevents neglecting of art and makes it expensive for the community.

Finally, it is necessary to evaluate the allocation of budget periodically. How has the situation with infrastructure changed? Does art develop in underfunded areas? Have projects provided enough opportunities to involve local artists and attract people to the public space?

If these questions have positive answers, the community will be able to modify its expenses on the basis of evaluation and not according to some formula.
