Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier inside Photoshop (Generative Fill). B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
