Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier infrastructure. The one platform every AI dev eventually uses.
