Kai's verdictS-tier for open-source model APIs. The default in this space.S-tier inside Photoshop (Generative Fill). B-tier standalone.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for model-shopping. I use this for every prototype before committing.
