Microsoft's preview model parachuted straight to third, but with only 5k+ battles, the score isn't stable yet—just take a look. Highest domestic rank is ByteDance's Seedream 5.0 Pro at sixth. For image editing, it's still American companies' turf. Section Highlights Pander Score New Benchmark | When users express strong opinions, does AI stick to facts or pander to the user? This new benchmark aims to quantify this. "AI pandering to users" finally has a ruler. Assistants that love marketing hype should be pulled out and tested.
