Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for coding.
