The Chinese Open-Source Model That Draws Pelicans Better Than GPT-4o

The Chinese Open-Source Model That Draws Pelicans Better Than GPT-4o GLM-5.1 just landed from Z.ai - a 754B parameter, 1.51TB, MIT-licensed model that is free on Hugging Face and available via OpenRouter. The model is the same size as their previous GLM-5 release, but something changed in how it handles creative tasks. Simon Willison ran his pelican test (asking models to draw a pelican on a bicycle as SVG). Most models produce static graphics. GLM-5.1 did something unexpected: it generated a full HTML page with CSS animations . The pelican's beak has a wobble animation. The wheels spin. It's not perfect - the animation broke positioning on the first try - but when prompted to fix it, the model correctly diagnosed the problem: "The issue is that CSS transform animations on SVG elements override the SVG transform attribute used for positioning, causing the pelican to lose its placement and fly off to the top-right. The fix is to separate positioning (SVG attribute) from animation (inner
