Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for open-source model APIs. The default in this space.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier infrastructure. The one platform every AI dev eventually uses.
