What this means
At this usage, a Blend subscription ($9/month) covers the providers below without you paying each one separately or managing API keys. If you use far more than this, registering your own keys (BYOKey) bills you at exactly the rates in this table.
How this is calculated
One message is assumed to cost roughly 1:3 input-to-output tokens. Short ≈ 300 output tokens, medium ≈ 800, long ≈ 2,500. Multiplied by 30 days. Real usage varies — treat this as an order of magnitude, not a bill.
