Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier infrastructure. The one platform every AI dev eventually uses.
