What the model leaves out

The plans include 1,000, 2,000, 5,000 and 10,000 credits a month, and add-on credits cost $0.04 each. The free tier has 50 credits. GovCloud pricing is about 20% higher.

Before you commit

A credit is a unit of agent work, not a request: complex prompts and spec tasks use more than one, and pricier models burn credits faster (a task on Sonnet 4.6 costs 1.3x the credits of Auto).
Monthly credits reset each billing month and unused ones don't roll over.
Add-on credits are bought in packs ($5 to $100) and charged immediately; they roll over but expire 12 months after purchase.
Each developer needs their own subscription; one can't be shared across a team.
