It's certainly still improving in many areas - like coding assist, for sure. I think video generation is still improving but it takes a shit ton of resources, so it's a bit slower. Maybe image generation has plateaued, but that could certainly be temporary. There are lots of more niche applications that are still progressing at a slower pace like I just read an article on using image processing AI in fertility clinics to better predict viability of embryos for implantation. Cool stuff that could actually improve people's lives.
