What it does best
Every line here comes from our own runs of Grok Imagine 1.5.
Signs you can read
On our night street, the red LIQUORS sign was sharp and spelled right, with BAR at the edge. On the same prompt, the other six each gave us a blurred, made-up or misspelled sign.
Every sign right; 6 other models each got one wrong
Holds the drift
Our rally car slid through the bend toward the camera and held the slide. It kept the same number 7 roundel on the door from start to end.
Same car and number for the whole 5 s clip
