For me it is very much hit or miss. I use claude sonnet with Cline. Sometimes I'm blown away that it can create a new page with CRUD functionality, nice UI etc. in one go. Another time it struggles to create a simple web page. Yesterday I needed a very simple landing page. My prompt was something along `Very dark grainy background with centered "name of the page" text.`. It couldn't get neither the background, nor the centering right. Later when it got one right, it screwed up the second. I had to give up after consuming ~$1.5 because we were not getting closer to the result.
Grok3 has been amazing, but it keeps on wanting me to do dark mode for an app I’m creating. When I finally said yes, it wasn’t able to get dark ode to work, despite multiple tries. Was funny tbh.
