Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for model-shopping. I use this for every prototype before committing.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier inside Photoshop (Generative Fill). B-tier standalone.
