Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for builders. The right primitives. What Kai is built on under the hood.
