Cartesia Scale plan accounts. Let me be super clear about what you're getting here.
8,020,000 model credits— this is one-time, sitting in account ready to use.
$300 voice agent balance — this renews EVERY MONTH for 12 months. So you're getting $3,600 worth of agent credits over the year. Not $300 total. $300 per month, 12 times.
That's massive value if you're building anything with voice agents.
12 months subscription included. After that it needs renewal but you've got a full year.
WHY CARTESIA
Fastest voice AI right now. Sub-100ms latency. Other platforms have that awkward delay when AI responds — Cartesia doesn't. Feels like real conversation.
If you're building voice agents, customer service bots, AI calling systems — that speed difference matters. Users notice.
