What one pool makes

Code by day.Posters by night.

Most of what members do is real work — GPT, mostly writing software. The rest is play: images and short films with Seedance, Hailuo H3-Max and Wan 3.0, Hong Kong in every frame.

94%

of usage over the last 90 days was GPT text — mostly writing code.
