Anvisha's take
Grok Imagine Video 1.5 is quick, cheap enough and unpredictable. Every clip came back in under 50 seconds, the market and harbour are good, and the title card is clean once a stray 'MME' clears off the first frame. But it burned a subtitle caption into the speaking woman's clip, which nobody asked for, and the pour-over turned into a kettle dripping into a bowl from a height. The self-portrait is a chrome robot holding a glowing X on a rooftop, so it knows whose model it is.
