How we ran it<br>Every model received the identical prompt in a single turn: no tools, no retries, no human edits. The first SVG returned is the one shown, rendered exactly as returned. The frontier round ran via each vendor’s raw API (latency is wall-clock for the full response, including any reasoning); the Claude family round ran via our agent harness, whose latencies include a small overhead.
