Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier in its niche. The only one that actually gets emotion right.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
