# Claude Sonnet 5.5 · xhigh SVG

Simon Willison tested Claude Sonnet 5.5: the xhigh run took 41 seconds and cost about 5.74 cents, producing an SVG with a mostly correct frame, legs, pedals and chain, but a misshapen blue bicycle helmet. The max run spent 128,000 tokens thinking and failed to return an SVG.
