Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier inside Photoshop (Generative Fill). B-tier standalone.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
