VECTOR, a public prompt-injection filter challenge

○Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content ✦Pretty: notable design, copy, craft, or presentation ◆Pro: polished, finished-feeling, serious, or operationally mature ◇Niche: specific audience, workflow, or unusually focused use case ◉Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

A live prototype asks visitors to test a classifier designed to catch prompt-injection attempts before they reach a downstream language model.

Why it surfaced

VECTOR turns filter-breaking into a public red-team exercise: visitors submit role-play prompts, encoding tricks, and instruction overrides, then can report verified bypasses for public credit and retraining. The site is unusually candid about its limits—the filter logic is simulated client-side and the launch leaderboard is empty by design.
