Kai's verdictS-tier for open-source model APIs. The default in this space.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier infrastructure. The one platform every AI dev eventually uses.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
